Master S series

FAQ

Master S series: Direct tap water intake, built-in PP cotton, KDF, and activated carbon pre-treatment + Dow RO membrane, complete with a complete water purification process;

Master-D series: Can only be connected to pre-treated pure water/distilled water/deionized water, no RO reverse osmosis module, suitable for laboratories with existing pre-purified water systems.

The end-stage double-layer PES filtration can retain particles >0.1μm; high-end UVF/UF models are equipped with multi-stage purification columns to remove RNase and DNase, suitable for molecular biology experiments such as PCR and protein analysis.

The dual-outlet design simultaneously produces RO pure water + 18.2 MΩ・cm ultrapure water; the Master-D series has a maximum water production rate of 2L/min, and the Master series is available in S15 and S30 flow rate specifications, which can be selected according to needs.

Ultrapure water can stably reach 18.2 MΩ・cm at 25℃; deionized water resistivity ≥5 MΩ・cm. It fully complies with various top-level laboratory water standards such as ASTM, CAP, CLSI, EP, and USP, and is suitable for high-precision experiments such as cell culture, molecular experiments, and physicochemical analysis.
