  • Depending on their age, chemical boxes differ in equipment and complexity. Classic chemical laboratories are available for ages eight, nine, ten, eleven and twelve years.
  • In addition to classic chemistry kits, there are experiment kits that deal with the growth of crystals or chemical lighting phenomena. Combination boxes that also convey physical and electronic knowledge are also available on the market.

Learning natural sciences in a playful way – this is possible with experiment kits from a wide range of disciplines. One of the classics among them is the chemistry kit, which u. a. is also referred to as a chemistry laboratory or chemistry kit. Such experiment kits for chemistry don’t just convey brittle theory. You are also able to, Inspire children with practical experiments and introduce them to the world of chemistry.

Incidentally, the importance of chemical laboratories for children goes far beyond promoting their sense of discovery or as preparation for school content. Some are lucky to discover his passion through the right experiment kit, who he or she also wants to follow in later professional life.

So that you are well informed and your children Carefree entry into the world of chemical science, we have in our chemistry kit comparison 2019/2020, in which you will hopefully find your personal chemistry kit comparison winner, the best chemical kits compared. In our buying advice we inform you about the different types of chemical kits and tell you what you should pay special attention to when buying.

1. Make chemistry tangible – experiments for children and adolescents

History of the chemistry kit

Chemistry experiment kits for adult hobby chemists and certain professional groups already existed towards the end of the 18th century. The Jena pharmacist Johann Friedrich August Göttling launched a so-called "Probir-Cabinet" in 1790, which u. a. for doctors, mineralogists, technologists, manufacturers and economists. In 1927 the first chemistry laboratory of the Franckh-Kosmos Verlag came onto the market, which is still the market leader in Germany in this field.

Children are curious and hungry to discover the world. If you want to support your little ones in this daring venture, you can consider whether instead of conventional toys, the purchase of a chemical box for children or an experiment system from another scientific area could be considered.

Such kits are always tried and tested pedagogically. Thanks to the exciting chemistry kit experiments, many young people and children can get excited about a scientific area that would otherwise cause frustration and yawning boredom at school due to the high theoretical content.

Chemistry experiments often inspire young students.

With one or the other it can even happen that Such initial contact leads to ongoing interest, which can ultimately even be decisive for the choice of profession. In general, it can be said that the field of chemistry for children is best understood through chemical experiments. So that boredom does not occur after a short time, many chemistry sets advertise with a large variety of experiments, which is explained precisely, easily understandable and step by step in the enclosed instruction booklet.

An interesting concept, which should also help to promote young people interested in chemistry, has been offered by the chemical and pharmaceutical company Merck KgaA and the TU Darmstadt in cooperation with the Hessian Ministry of Culture since 2008 as part of a so-called "Junior Laboratory".

In the following overview we have summarized the advantages and disadvantages that a modular kit for chemistry offers from an educational point of view:

  • introduces young people to chemistry in a playful way
  • can thanks to exciting experiments light excite
  • creates an understanding of scientific phenomena
  • can possibly serve as an early professional orientation
  • is not always harmless
  • should only be used in the presence of adults

2. What types of chemical building blocks are there??

If you are concerned with a chemical kit test or comparison, you will notice that chemical kits can be differentiated in terms of their equipment. This is usually dependent on the age recommendation given by the manufacturer. The higher the recommended age, the more extensive and complex the equipment and test series.

2.1. Differentiation by age

Most chemical laboratories on the market can be divided into five different age groups:

The equipment of the chemical boxes and the complexity of the experiments depend on the age recommendation.

Chemical construction kit from 8 years:
Simple equipment and simple experiments, often without or with only a few (non-hazardous) chemicals supplied, provide initial insights into the world of chemistry.

  • Chemical construction kit from 9 years:
    Simple equipment and simple experiments, mostly with a few chemicals supplied, go beyond first impressions and let young researchers get to know the most important chemical processes.
  • Chemical construction kit from 10 years:
    Medium-sized equipment and simple to moderately difficult experiments, usually with several chemicals supplied, impart basic knowledge of known chemical substances and introduce the basics of chemical work practice.
  • Complex test series are possible with a chemical construction kit for young people from the age of 12.

    Chemical construction kit from 11 years:
    Medium to complex equipment and medium-heavy experiments, usually with many chemicals and Bunsen burners included, impart basic and advanced knowledge of chemical substances and introduce organic and inorganic chemistry, electrochemistry and the basics of chemical work practice.

  • Chemical construction kit from 12 years:
    Complex equipment and medium to complex experiments and series of tests, mostly with many chemicals and Bunsen burners included, impart in-depth knowledge in organic and inorganic chemistry, deepen diverse working techniques and lead into the world of chemical theory (chemical formulas, atomic structure, periodic table, chemical reactions, element families, etc .) on.
  • 2.2. Differentiation according to thematic focus

    Since there are chemical experiments that deal with organic and inorganic chemistry, there are other experimental systems that deal with specific areas of chemistry or that can be at least partially assigned to chemistry, so a chemistry kit test should also be used to distinguish between such special features.

    Chemistry set type particularities
    Classic chemical construction kit
    • A classic chemistry kit introduces experiments into the sub-areas of inorganic (carbon-free compounds) and organic chemistry (carbon-containing compounds).
    • Depending on the age recommendation, classic chemical kits differ in terms of the equipment and complexity of the experiments and test series.
    Chemical construction kit luminous phenomena
    • A chemical kit for chemical lighting focuses on u. a. also on the so-called physical chemistry (properties of substances and their conversion) and on the investigation of the luminous chemical luminol.
    • The experiments are primarily aimed at mixing different substances with luminol and the resulting fascinating lighting properties.
    Chemical building kit grow crystals
    • A chemical construction kit with which crystals can be grown moves on the border to the mineralogy department (origin, properties and use of minerals).
    • In contrast to classic chemistry kits, there are no typical experiments on organic or inorganic chemistry. Such a laboratory is more suitable for craft fans with mineralogical interest.
    Combination kit

    • A combination kit is often aimed at elementary school students (some of them from the age of six) and contains various experiments on a wide range of subjects (biology, technology, natural phenomena).
    • It should inspire young children to learn, which is why, in addition to experiments, there are also tasks for learning control and documentation that are intended to deepen and consolidate the knowledge learned.

    3. What is a chemistry kit equipped with??

    In our chemical kit comparison, we were able to determine that there are very different models with different chemicals and accessories. However, there are some important ingredients that should be included in any good chemistry experiment kit.

    Chemical laboratory accessories: Not every chemical box contains the same equipment.

    Essential accessories include:
    Test tubes, measuring cups, dropper pipettes, safety glasses, measuring spoons and a corresponding instruction booklet. Larger chemical kits for children and adolescents often also contain a Bunsen burner. A burner is mainly needed for more complex experiments, in which certain substances can only be created or converted under the influence of heat.

    The basic chemical equipment usually includes:
    Calcium carbonate, copper sulfate, sulfur, zinc sheet, iron arrow shavings, citric or tartaric acid as well as quick test strips such as litmus and universal indicator paper.

    Interesting: Since many of the chemicals in chemical boxes are classified as hazardous substances that can be assigned to the categories irritant, oxidizing or harmful to health, chemical boxes have meanwhile come onto the market that do not have to be equipped with chemicals, in whole or in part. In order to be able to carry out all experiments, substances such as acids or alkalis must then also be purchased. This also applies to chemical kits from 8 years of age. However, they are usually limited to simple experiments with non-hazardous everyday chemicals from the household, without the need to purchase substances such as alkalis or acids.

    4. Purchase criteria for chemical kits: You have to pay attention to this

    The age recommendation should be observed when purchasing a chemical kit.

    Chemical kits should be fun and introduce young people to the exciting world of chemical substances. However, since not every chemical box is constructed identically and there are some significant differences, we would like to briefly present the most important purchase criteria in our chemical laboratory comparison:

    4.1. Recommended age

    Of course, the age recommendation plays an important role. Chemical kits are developed with educational support, so that they vary in their equipment and in the complexity of the experiments and test series. So to guarantee your children the greatest possible fun and learning effect, you should use products that are appropriate for the age of your children.

    By the way: There are no chemical kits for professionals on the market, nor special experiment kits for adults. Of course, this does not mean that you, as a hobby chemist, cannot benefit from the test series of the chemical boxes. If you want to buy a kit for chemistry for your purposes, we recommend models that are suitable for children and adolescents from the age of 12.

    4.2. Scope – chemicals and accessories

    The number of chemical tests that can be carried out depends on the age recommendation and the scope of the components supplied.

    Depending on the age recommendation, the number of chemicals and the accessories supplied also vary. As the experiments and series of experiments become more complex with increasing age, adequate equipment is of course also required. In principle, the following applies: The more diverse and extensive the experiments in a (classic) chemistry experiment kit, the higher the number of chemicals and everyday items supplied.

    4.3. Number of experiments that can be carried out

    The number of experiments that can be performed depends on both the age recommendation and the scope of the chemical kit. Chemical kits for children aged 8 or 9 often have a significantly smaller repertoire of tests that can be carried out than is the case with chemical kits for 10-, 11- or 12-year-olds. This is not necessarily a disadvantage, but due to the fact that many chemical experiments are simply not yet suitable for younger children.

    Remember: Most chemistry kits do not include all of the ingredients to perform all of the experiments in the instruction booklet. As a rule, some household foods and substances are also required. In addition, you may have to get additional chemicals from the pharmacy or utensils such as batteries, etc..

    4.4. Safety glasses and Bunsen burners

    A chemistry kit with burner is only suitable for older children from 11 or 12 years.

    Safety glasses are important for safety when experimenting and prevents chemicals from getting into the eyes. It should be part of every good chemical kit. However, since there is usually only one pair of safety glasses for children, but the supervisor also needs appropriate eye protection, we recommend that you take a look at our safety glasses comparison at this point.

    Depending on the age recommendation, it may also happen that a chemical kit is equipped with a Bunsen burner. A Bunsen burner is particularly needed for more complex experiments, where chemical reactions can only take place with the addition of heat (endothermic reaction). If experiments with Bunsen burners are planned, you should make sure that it is part of the experiment kit. Otherwise you will incur corresponding extra costs.

    5. Security measures

    If you are experimenting with an experiment kit for chemistry, you should urgently follow some safety rules, which we would like to briefly introduce to you in our chemistry kit comparison:

      Observe age recommendation: Be sure to follow the recommended age. The experiments are tailored to the age of the children. Sometimes, for example, chemical kits from 12 years of age contain more dangerous chemicals than chemical kits from 10 or 8 years of age.

    Safety glasses must always be worn during chemical experiments.

    Use under adult supervision: Although most chemicals in chemical laboratories are not extremely dangerous, some of them pose a health hazard when ingested. To ensure responsible use of such substances, an adult should always be present.

  • Perform experiments as directed: Even if explosions or dangerous reactions of the supplied materials are excluded, the instructions should always be followed (so that the experiments work as described).
  • Do not bring chemicals into contact with the body: Avoid direct physical contact with the chemicals. This applies especially to the mouth and eyes.
  • Wear safety glasses: To adequately protect the eyes, you and your child should always wear eye protection.
  • 6. Approval and quality control

    In an interview with Comparison.org, the expert Sonja Briz informed us about the approval, quality control and the awarding of seals: Chemical building kits would not have to be in Germany or Europe

    “Be approved by a central body. They are subject to the European directive on the safety of toys (2009/48 / EG) and are regulated very precisely in an extra standard part within the EN71 series (toy safety standard). EN71-4 for experiment kits for chemical and similar experiments describes in great detail which chemicals may be contained in chemical kits and how they are handled safely. It contains requirements for the experimental material, e.g. For example, that only heat-resistant glass or child-proof chemical containers may be used, but also precise information for adult supervisors and safety rules for the experimenting child. ”

    Before experiment kits for chemistry can be launched on the market, it must also be ensured that the requirements of both chemicals and toy law are met. Only when the manufacturers have carried out a risk assessment for their product and this conformity assessment procedure has been completed,

    “May the CE mark [as a kind of seal, A. d. R.] on the product. "

    7. Major brands and manufacturers

    The market for chemical kits for children is quite manageable. For decades, the Kosmos publishing house has dominated events in Germany. Although there are occasionally products from other manufacturers, such as Ravensburger or Clementoni, the Kosmos publishing house in particular is always characterized by a variety of innovations and new ideas in this area.

    A Kosmos chemical box was a must in every child’s room in the 1960s to 1980s. Chemical kits from Kosmos are still very popular today

    The first Kosmos experiment kit came onto the market almost 100 years ago (in 1922). Since then, the company has released more than 140 different experiment kits. The products enjoyed great popularity, particularly in the 1960s to 1980s, when it was possible to speak of a real boom in chemistry and experimentation laboratories.

    Although the wave of enthusiasm has flattened somewhat since the beginning of the 90s and the spectacularity of the chemical boxes has decreased somewhat due to numerous standards and regulations, Kosmos has expanded its position as market leader in recent years. In addition to chemical kits, different kits are currently a. from the fields of physics, electronics, astronomy and renewable energies.

    8. Questions and answers about the subject of chemistry experiment kits

    8.1. Where can you buy a chemistry kit?

    Although a chemical experimentation system is not seen as a conventional toy, it can be used like other construction kits in appropriate toy stores such as Spielemax or Toys’R’Us. In addition, you can Buy chemical laboratories online, which gives you some advantages:

    • greater choice of products
    • Buying advice from online guides
    • Order conveniently from home
    • Delivery directly to your home
    • no personal advice in the shop

    8.2. What does a chemical construction kit cost??

    Kosmos experiments: The Kosmos chemistry laboratory C 3000 is suitable for young people from the age of 12. Of course, it can also be used as a chemistry kit for students or hobby chemists.

    If you are on the search are the best chemical kit, you should always take into account the age of your children. Depending on the age recommendation, the scope of equipment and chemicals as well as the complexity of the experiments and test series increase.

    This also affects the price. A cheap chemistry kit for 8-10 year olds usually costs between 10 and 35 euros. If, on the other hand, you want to buy a chemistry kit that is suitable for 11 or 12 year olds (and older people interested in chemistry), you have to dig deeper. Corresponding premium models usually cost more than 100 euros.

    8.3. A chemical construction kit is dangerous?

    You don’t have to be afraid of a chemical building block explosion thanks to the relatively harmless chemicals it contains.

    In principle, caring parents can be reassured at this point. Because a chemistry lab is chemistry for beginners contain neither strong poisons nor flammable substances. Today, many chemical building kits use household chemicals, such as baking soda, soda or ammonia solution. Most of them are harmless and well suited for home experiments.

    In addition, there are also some chemicals that can be irritating and hazardous to health when taken, so that an adult should always be present during the experiments.

    Did you know? Thanks to the toy standard EN71, the chemical prohibition regulation of the German explosives law and the basic material monitoring law, many chemicals have been largely banished from the chemical kits. Although safety has increased in the course of such measures, the chemical kits have also lost some of their fascination and joy in discovery.

    8.4. Where can I have a chemical construction kit refilled??

    Usually you can used substances can be reordered directly from the manufacturer. For example, Kosmos Verlag, the largest manufacturer of chemical building blocks in Germany, offers the opportunity to buy chemicals and spare parts for every product on its website.

    Important: If you want to dispose of your chemical construction kit, do not pour the remaining chemicals into the sink. Return vials and tubes that still contain chemicals to a toxic substance collection point so that they can be disposed of properly. All other materials can be disposed of in normal household waste.

    8.5. Did the Stiftung Warentest carry out a chemical building block test?

    The Stiftung Warentest has not yet carried out a test on the topic of chemical building kits. However, if you are generally interested in building blocks with a scientific or technical focus and their pedagogical value, then you could take a look at the historical test of the foundation from 1972, issue 12/1972, in which it examined ten different construction building blocks.
