What is Grade 3 Laboratory Water?

Grade 3 Laboratory Water is a quality type of water that meets government specifications that are laid out by British or International standards. This water is intended for laboratory use only. Grade 3 water is produced either by a single distillation, reverse osmosis or through deionisation.

According to guidelines, Grade 3 lab water should contain no more than the following maximum contaminant levels:



Grade 3


Resistivity at 25 oC [MΩ·cm]


Conductivity at 25 oC [μS·cm−1]



pH at 25oC



Total Organic Carbon/p.p.b.(μg/l)

Total Solids




Sillica (μg/ml)




What is it Used For?

Grade 3 Laboratory Water is used for the preparation of reagents and solutions. It is intended for use in analytical work and testing. It can be used in a laboratory water bath to incubate samples of cell cultures, warm reagents or to melt substrates.

It can also be used in general laboratory applications, such as in buffer and pH solutions. It can also be used to feed other water systems, like laboratory taps.
