Biological research laboratory pure water machine: VE-Ds Series
1.Low equipment operation costs.

2.The machine use the high quality RO membrane to have a longer service life.

3.Low pyrogen and low TOC, meets the water quality demands for polymer biological experiments and precision equipment. 

4.The operation is simple and convenient, and the consumable is easy to change (Just pull out the plug and replace it with a new one).
Working process:

The pretreatment steps of lab purification machine using PP cotton, sand filter, activated carbon filter. The main purpose is to remove the suspended solids in raw water, including sediment particles ,organic colloids,organic matter,odor,chlorine and other impurities.
Then the water enter the Reverse Osmosis system, most of the dissolved salts, bacteria, hot stream will be filtered out, to ensure production water quality meet the standards.
UV sterilization eliminate the organic matter in water, to ensure the pure water won‘t have any effect on the results of the experiment. 

At last, in order to get high pure water with low conductivity (1 micro Siemens per centimeter), the ultra purification column group is equipped, exchanging the anions and cations with hydroxide ions and hydrogen ions.


1. Detect the high pure water quality online.

2. Automatic cleaning procedure for RO membrane, extended the machine service life.

3. The production rate of an RO system depends on the water temperature (25 °C).

4. Built-in RO membrane anti-scaling program, automatically clean RO membrane.

5. Purification water machine with an integrated reverse osmosis system to transform tap water to high pure water.
