Manifolds Vacuum Filtration (With Collection Bottle)
Brand: ZX
Summary of use:
This product is made of high-quality extra hard glass. It is sparkling and crystal-clear. Its thickness is even. The performance of the withstanding voltage and its leakproofness is very good, and its size agrees with the international standard size.
It can be used for sterilization at high temperature and high pressure. It is mainly used in the filtration of the HPLC mobile phase and has the function of outgas to guarantee the clean of mobile phase and avoid the blockage of HPLC liquid flow path.
We have various types of glass holders. M type is connected by the ground glass. Type S is connected by Stopper.
Glass material specification:
