Product features
Straight two-way stopcock is made of high-quality borosilicate glass, which has extremely high chemical and thermal stability. It can withstand the erosion of various chemical reagents and will not react with most substances, ensure that it will not contaminate experimental samples or affect experimental results during use.
The glass material makes the stopcock extremely transparent, allows users to clearly observe the flow of fluid inside. Glass has good tolerance to most chemicals, and the glass stopcock can remain stable. The two-way stopcock can easily divide and merge fluids or switch between different fluid sources. The operation method is relatively simple and easy to get started and master. The sealing performance between the piston and the glass tube is good, which can effectively prevent fluid leakage and ensure the purity and quality of the fluid. The straight design is simple and elegant, takes up little space, and is easy to install and operate. The straight structure also makes the fluid flow path smoother when passing through the stopcock, reduces fluid resistance and improves the efficiency of fluid transmission.
Straight two-way stopcock has low expansion rate, high temperature resistance, acid and alkali resistance, high strength, high hardness, high transmittance, high chemical stability, flexible piston rotation, no leakage, fine grinding, no leakage, no The protrusion is beautiful and generous, the workmanship is solid, the light transmittance is good, the transparency is high, the surface is beautiful and generous, strong and durable, high strength and high hardness.
