Biotech Research Demands Highly Purified Water

Often overlooked, highly purified water is an absolute requirement for successful biotechnology research, and now a new and sophisticated water purification system has become available.

The new purification system, the ELGA LabWater Purelab Pulse, (Marlow, United Kingdom) has been developed to produce consistently highly pure type II level water at economical running costs for a wide range of applications including cell culture and media preparation. Type II water is basic for general laboratory applications requiring higher inorganic purity as well as being suitable for clinical analyzers, electrochemistry, sample dilution, media preparation, and radioimmunoassay.

ELGA's Pulse technology integrates EDI (electrodeionization), which combines ion exchange resins and ion-selective membranes, with direct current to remove ionized impurities from water efficiently. It is complemented by pretreatment, reverse osmosis, and a 254 nm UV lamp to produce type II pure water that the manufacturer says meets and exceeds European, U.S., and Japanese pharmacopeia standards. In addition, the PURELAB Pulse can be fitted with a point-of-use biofilter to reduce bacteria levels to less than one colony-forming unit per 10 mL.

The purification system has been designed to fit into any laboratory environment and is easy to operate and maintain. It can be wall or bench mounted for convenient access and can be fitted with ELGA's unique wrap-around reservoir to save valuable space.
