Product features

Straight capillary stopcock is made of high-quality borosilicate glass, it has extremely high chemical and thermal stability.

The glass material is transparent, and users can directly observe the flow of fluid in the capillary tube, changes in liquid level, and whether there are bubbles and other issues, improving the accuracy and efficiency of operations. Glass has good resistance to most chemicals, makes glass Straight capillary stopcock safe for use in a variety of chemical environments. The glass stopcock remain stable, ensure reliability and accuracy of fluid transfer. The straight appearance also facilitates connection and integration with other experimental devices, makes it easy to build complex experimental systems. The inner diameter of the capillary tube is extremely small and can accurately control the passage of small flow rates of fluid. Tight piston fit, the tight fit between the piston and the glass tube can effectively prevent fluid leakage.

Straight capillary 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 protruding feeling,beautiful and elegant, solid workmanship, good light transmittance, high transparency, beautiful and elegant, strong and durable, high strength and high hardness.
