Molecular biology, life sciences, genetic research, cell culture, amino acid analysis, protein purification, toxicology research, drug development, medical testing


110-220V/50-60Hz; 120W

Filter function

PP: PP cotton filter, remove impurities (greater than 5 micron) such as suspended solid, rust, sludge, colloid, etc.

AC: Granular activated carbon filter: remove color, odor, residual chlorine and heavy metals

RO: Reverse osmosis membrane: filter out <1nm pollutants, ions, particles

RO: Reverse osmosis membrane: filter out <1nm pollutants, ions, particles

EDI module: Ensure the purity of water and maintain the life of consumables

UV: UV germicidal lamp: sterilization device, decomposition and photo oxidation OC, lower TOC

UP: Ultra-purification column: ion exchange resin bed, H+ and OH- ion removal

TF: 0.2μm terminal filter, final removal for < 0.2μm bacteria
