Borosilicate 3.3 Glass Tube

Borosilicate 3.3 Glass Tube

Borosilicate 3.3 glass tube, which is equivalent with Schott's Duran tube, it is heat resistant Pyrex glass tube.

Borosilicate Glass 3.3 - Engineered for Excellence

Our borosilicate glass 3.3 tube is manufactured to meet the most demanding requirements of laboratory, industrial,

and technical applications. With a low coefficient of thermal expansion, this material exhibits exceptional resistance

to thermal shock and chemical corrosion, making it the ideal choice for applications where reliability and performance

are critical.
