Glass Test Tube – High Temperature & Corrosion Resistance

GTT-01: Glass test tube is widely used in the lab tests.

Glass test tube, also known as culture tube and sample tube, is a common and widely used glassware, which has a finger-like length, open top and closed bottom. It can be made of soda-lime material, borosilicate glass or quartz glass. And borosilicate glass and quartz glass test tube can withstand high temperatures up to several hundred celsuis.

To suit different applications, the glass test tube can be made into multiple lengths and outer diameter. Detailed specs refer to the Table 1: Common Specs of Glass Test Tube.

Glass test tube is commonly supplied in round bottom and some are flat bottom. Besides, the stopper can be plastic, cork, quartz stopper and plastic screw cap.
