Our glass reactors are made of robust borosilicate glass, providing an efficient and versatile choice for performing chemical reactions compared to conventional reactors made of stainless steel or plastic.

Resistant to aggressive chemicals, our glass reactor provides precision and control for all reactions with optimal heat energy transfer for excellent temperature control. Heat and cold loss can be minimized by an optional vacuum jacket, while the transparency of the glass allows direct visual control of the reaction process.

The glass reactor can be used for a range of chemical reactions, including esterifications, hydrolyses, oxidations, polymerizations and more for chemical, pharmaceutical, food and cosmetics industries. Customizable accessories for different stirrer types, lid designs and superstructures can be tailored to your application.
