Check Valve(HPLC Pump)

The check valve in liquid chromatography is a key component in the high-pressure infusion system, mainly used to control the unidirectional flow of the mobile phase, prevent backflow, and ensure the stability of flow rate and pressure.

Xinsheng Technology check valves are available in two specifications: ruby (standard) and ceramic ball (Swiss imported). Among them, the ruby check valve features light weight, corrosion resistance, and non-conductivity. The ceramic ball check valve has extremely high hardness, heat resistance, and low density. Moreover, the ceramic ball check valve is more corrosion-resistant than the ruby check valve. For specific requirements, you can choose based on the samples you need to analyze.
