Product Introduction
Many colors are available. The sealed protection device effectively prevents leakage. The bottle body is transparent and smooth, resistant to high and low temperatures. Amber Low Borosilicate Glass Tubing is used in the storage or transportation of reagents and samples. Its design has the characteristics of convenient use, strong sealing, etc., and can be stored and transported according to the actual amount required. Its bottle body is made of borosilicate glass. Compared with ordinary glass, borosilicate glass is characterized by a very low thermal expansion coefficient, is less affected by temperature differences, and does not undergo significant thermal expansion and contraction. Therefore, it has high temperature resistance and shows better stability under high heat and cold conditions.
