Water is a reagent that is often overlooked, but critical. The laboratory has those types? What level can you meet? Different experiments have those requirements for water? To clarify these blurred concepts, forward this post AA7 China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry 1. Type of Water in Lab:

Laboratory A commonly used pure water, although it is cheap, but extremely energy consuming and feeding and slow speed, the application will gradually decrease. Distilled water can remove most of the contaminants in the water, but volatile impurities cannot be removed, such as carbon dioxide, ammonia , Silica and some organic matter. Fresh distilled water is sterile, but the bacteria is easily propagated after storage; in addition, the stored container is also very particular, if it is non-inert substance, the shaping material of ion and containers, the precipitation of secondary Pollution.

The ion exchange resin is applied to remove the anion and cation in water, but there is still a soluble organic substance in the water, which can contaminate the ion exchange column to reduce its efficacy. After the deposit water is stored, it is easy to cause the breeding of bacteria. AA7 China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
Water:

The principle of its generation is that the water molecules are in the action of pressure, and the impurities in the water are discharged by the reverse osmosis membrane. The anti-seepage overcomes distilled water and deionized water. Many disadvantages, using reverse osmosis techniques to remove dissolved salts, colloids, bacteria, viruses, bacterial endotoxins and most organic substances, but the anti-osmosis membrane produced by different manufacturers is very affected.

The standard is 18.2m Omega; CM. However, ultrapure water is different in terms of TOC, bacteria, and endotoxin.To determine according to experimental requirements, such as cell culture requires bacteria and endotoxin requirements, and HPLC requires TOC low.

The concentration of carbon in water, reflects the content of the oxidation of the oxidation, and the unit is ppm or PPB.
