2, Features

 

Fed tap water,produces ultra-pure water with conductivity of 1-5 μS/cm at 15-20 L/h,even if the source water is of relative poorer quality.Two-stage reverse osmosis system has with dual pumps,dual RO membranes,and a middle tank.Compared with single-stage system,two-stage RO purification system will not only produce purified water with more stable quality,but also reduce the cost of subsequent purification modules.

 

Applications

1) Glassware washing

2) Spectrometry measurements

3) DNA sequence analysis

4) Sample dilution and reagent preparation

5) Microbiological analysis

6) Buffer and media preparation

7) Electrophoresis,gel analysis

8) General Chemistry and Qualitative Analysis

9) TOC analyses,IC

10) HPLC/GC-MS/ICP-AES

11) Mammalian Cell Culture

12)Water analysis and general HPLC
