STA pyrex 3.3 thinner thickness borosilicate glass tube

Description:

Borosilicate glass tubing and rods made by us are well-known for their stability and pressure resistance, good workability and high thermal shock resistance. We have a very low rate of thermal expansion, which makes it an excellent material for laboratory glassware and for use in large-scale technological plants in the chemical apparatus industry. Our products are resistant to corrosion and remain absolutely neutral, even to aggressive chemicals, in nearly all fields of chemistry. This brings them a great advantage over other materials. Borosilicate glass is extremely resistant to water, acids, salt solutions, organic substances and halogens. Tubing, capillary and rod also have a high alkali resistance for physical and chemical properties.
