Water source safety, micro-pollution control and drinking water security have increasingly become routine and critical tasks in China's water quality monitoring and testing. Water quality testing is a national and regional water safety initiative that carries important social responsibilities and practical mandates.
The functions of a water quality testing laboratory are determined by the inherent properties of testing items as well as the requirements for water sample collection and preservation. On-site measurement is conducted for parameters including colority, turbidity, water temperature, pH value, electrical conductivity and dissolved oxygen during water sample collection.
A full-scale water quality testing and analysis laboratory is functionally divided into multiple independent rooms: atomic absorption room, atomic fluorescence room, ion chromatography room, liquid chromatography room, high-temperature laboratory, microbial testing room, radiological laboratory, changing room, general laboratory and comprehensive laboratory, as well as reagent storage room and other functional zones.
Laboratory furniture and equipment deployed in such facilities mainly consist of laboratory benches, washing stations, instrument tables, fume hoods, sample storage cabinets, document cabinets, acid-base storage cabinets, gas cylinder cabinets, medical reagent boxes, reagent cabinets, instrument cabinets, glassware cabinets and a full range of supporting laboratory furniture and facilities.
Since water quality testing laboratories are primarily engaged in water sample analysis, the indoor environment tends to be humid. A large quantity of laboratory glassware needs to be cleaned after testing procedures. Therefore, laboratory benches in the washing area shall be made of thermosetting resin material with excellent moisture resistance. This material delivers superior moisture-proof and antibacterial performance, allows easy cleaning and ensures higher operational safety.
In addition, to create an optimal experimental environment, laboratory benches shall be equipped with dry-wet separation modules to achieve moisture and corrosion resistance, and to prevent cross-interference between the washing area and experimental operation area. To meet the laboratory's water, electricity and gas supply demands for testing activities, partitioned central laboratory benches with integrated full-station water, electricity and gas supply modules are recommended for deployment.
