Screw threaded glass tubes
Screw-on tubes made of soda-lime glass or borosilicate glass.
Borosilicate glass is a type of glass with very high resistance to sudden temperature changes. This makes it ideal when tubes need to be heated and cooled quickly without risk of breakage. Soda-lime glass is used in most laboratory techniques where the tube is not subjected to significant thermal processes.
Tubes with excellent repeatability and dimensional stability: diameter, height, and wall thickness.
Supplied without a cap.
