what is lab grade water
deionised water machine lab grade used in the laboratory can be divided into three levels, with strict standards for first and second level water, suitable for high-precision experimental needs.
First level water: This level of deionized water usually has a water resistance of 18.2 M Ω· cm, which meets the GB/T6682-2008 standard. This type of water quality is suitable for experiments that require extremely high purity, such as certain chemical analysis and biological experiments.
Secondary water: The electrical resistivity of secondary water is relatively low, generally between 0.1 and 0.5 mS/m. It suitable for general chemical analysis experiments.
Third level water: Third level water is mainly used for general laboratory water, with a high conductivity, usually above 0.5 mS/m.
In summary, the selection of a suitable deionized water machine should be based on the specific needs of the laboratory. And the grade standards of experimental water to ensure the accuracy and reliability of experimental results.
