Test kit

If you intend to buy one of our kits Student, Standard or Professional, but still hesitate with the purchase, the Test kit can help you to get acquainted with the most popular experiments contained in the full-featured Student, Standard or Professional kits. The Test kit contains a number of chemicals to perform 6-10 repetitions per experiment, providing sufficient capacity for preliminary demonstrations.

The Test kit contains 4 clearly written instruction cards, including a brief theoretical explanation of the experiments.

Experiments with hydrogels


Everything in one suitcase saving your time

You do not have to look for supplementary chemicals, every chemical you need is included so that you can start experimenting right now and for the most part without the need for a dedicated chemical laboratory.

Attractive chemical experiments

You will obtain all the chemicals you need to do the most attractive experiments that fascinate students and kindle their interest for science. Let them discover the interdisciplinary connections through experiments they fall in love with.

Safe according to the latest standards

We have designed the experiments that poisonous and corrosive substances are completely avoided in student experiments which thus meet the most stringent requirements of the current legislation. Therefore, even student of lower grades can also perform the experiments under the supervision of the teacher. All chemicals are labelled according to the latest CLP guidelines (Classification, Labelling and Packaging) and are provided with the corresponding Material Safety Data Sheets in English.

Methodically linked to the curriculum plans

The context of the experiments is linked to many topics that are commonly contained in curriculum plans of primary and secondary schools.

Instructions manuals for students and teachers

We provide clearly written student instruction cards, teacher´s methodological cards and a teacher's manual.

Possibility to refill the material

We offer to existing customers the possibility to purchase any part of the kits at reasonable prices.

Experiments in the Test kit

Peroxyoxalate chemiluminescence

  • nontoxic chemicals for peroxyoxalate chemiluminescence („motor of the reaction“) 
  • dyes for chemiluminescence

    • a green-yellow dye
    • a red dye
    • a yellow-orange dye

  • catalyst of the chemiluminescent reaction
  • non-toxic and non-flammable solvent
  • hydrogen peroxide source in a safe and highly efficient form
  • auxiliary pipettes and wooden spatulas

Description: Students will prepare in test tubes glowing chemiluminescent solutions with different colours. They will be able to influence the glow intensity (and reaction rate) by heating/cooling, change of pH and by addition of a catalyst.

Curriculum framework: Observation; Experiment; Safety; Chemical changes; Chemical reactions: factors influencing the course of the chemical reaction (temperature, pH, catalyst); Inorganic compounds: Use of acids and bases, neutralisation, pH; Organic compounds: heterocyclic compounds

Experiments with hydrogels

  • fluorescein for hydrogel dyeing
  • ready-made polyvinylalcohol solution (PVAL)
  • crosslinking reagent
  • solid organic acid for hydrogel decomposition
  • pH indicator for studies of pH influence on the hydrogel structure

Description: Students will prepare a crosslinked polymer (hydrogel) and verify its physical and chemical properties, especially its pH-dependent behaviour. As a result, they become acquainted with concepts of polymerization and reaction equilibrium.

Curriculum Framework: Chemical reaction: polymerisation, factors influencing the course of the chemical reaction (pH); Inorganic chemistry: acids and bases, pH, indicator; Organic compounds: hydrocarbon derivatives, use of their important derivatives; Chemistry and the society: plastics


  • pyroluminescence mixture
  • Al cups

Description: The teacher demonstrates the characteristic spectacular evidence of boron compounds - a highly luminous green flame of burning trimethyl borate.

Curriculum framework: Energy and the matter

Experiments with triboluminescence

  • a sample of a manganese complex that emits an intense green glow upon friction

Description: Students get acquainted with complex compounds that have interesting properties.

Curriculum framework: Coordination compounds; Energy and the matter

Photochemical blueprinting – cyanotypes

  • chemicals for preparation of the solutions for cyanotypes 
  • negatives for cyanotype printing

Description: Students will make their own cyanotype photographs with a photosensitive mixture of chemicals in the sunlight and thus get acquainted with an example of a photochemical reaction.

Curriculum framework: Chemical reaction: redox chemical changes, oxidizing and reducing agents; Chemical elements: iron; Inorganic chemistry: coordination compounds; Energy and chemical reactions
