Our company designs the small-scale water purification machine of laboratory totally accord with the GB 6682-1992. The laboratory water is divided into three ranks: First class water, second water and tertiary water. The conductivity of corresponding to water quality is 0.1uS/cm, 1uS/cm, 5uS/cm respectively.
The occasion with pure water in the laboratory:
The first class water is used for the analysis with the strict requirement testing, including having test of the requirement to the particle and analyzing the water in high-pressure liquid phase chromatogram.
Second water used in inorganic trace amount analyze, test, atom absorb spectral analysis.
Tertiary water used in general chemical analysis test, including ordinary titration analyze, washing beaker and capacity bottle.

The characteristic of the small-scale water
purification machine:
Make water full-automatically.
The machine is dual-purpose. Produce pure water and ultra pure water,
and measure with the online resistance value appearance.
The machine has the automatic washing program, so it can lengthen RO membrane
service time.
The appearance of the machine is exquisite and in good taste and the design
is rationally distributed. Tt is convenient to overhaul and change the
consumptive material.
