Precision Glass Tube with 0.001 mm Tolerance Used in Laboratory, Hospital
Precision glass tubes ith accurate dimension and 0.001 mm tolerance are made of soda-lime, borosilicate or quartz material. Because of their different sizes, various colors, acid, alkali resistance and low thermal expansion coefficient features, precision glass tubes are widely used with pistons and many precision instruments in laboratory, factory, hospital, and so on.
PGT-01: The short polished percision glass tube has good thermal and chemical properties.
PGT-02: The heavy wall precision glass capillary tubes have strong acid, alkali, high temperature resistance ability.
