Production & Package
Each glass test tube is produced by borosilicate heat-resistant glass material. We have flat bottom tubes and round bottom tubes for clients' choosing. We also accept customized glass tubes orders, if clients have any needs. Usually, we pack some pieces of glass tubes per inner box package, then some inner boxes in carton box.
Glass tubes are mainly cylindrical hollow-wares. Their special shape combined with the huge variety of glass types (like borosilicate, flint, aluminosilicate, soda lime, lead or quartz glass), allows the use of glass tubing in many applications. However, all of our glass tubes are made from borosilicate glass material. If you have any needs of cheap glass tubes, please contact us freely.
