No one laboratory can function without glassware, because reagents, reactants and other chemicals need to be stored somewhere. Conducting various types of analyzes, analytical surveys, studying of chemical and biological reactions, organic and inorganic synthesis – all these processes require the use of quality and safe containers. In this case, chemical glassware made of quartz glass will be extremely useful.

Glassware for laboratories has an exceptionally high resistance to high temperatures and practically does not expand when heated, so experiments can be carried out in this glassware at the temperature up to 1000°C.

Chemical glassware

Quartz chemical glassware is suitable for use at the temperature up to 1200°C. All products are designed for a long operating service life. Glassware for laboratories is characterized by resistance to chemical effect, high temperature conditions and their fluctuations. Furthermore, chemical glassware is characterized by its heat resistance and acid fastness.

Quartz crucibles are an indispensable equipment for metal processing. The requirements for the parameters of these products are very high, and it is quartz that comply with them in full.

In addition, quartz glass products has an excellent optical homogeneity, they are resistant to ionizing and laser radiation and practically do not absorb light. The glassware do not crack when exposed to the temperature of 800±20°C and the further cooled in water even after 20 thermal cyclings.
