They offer a wide range of flow-rates to suit your needs, advanced purification technologies to provide pure water on demand, plus microprocessor control for consistent quality. Different laboratory applications demand different water purity levels. ELGA offers a choice of general laboratory grade water systems in the PURELAB Option range to cover applications ranging from glassware washing and the feeding of ultra-pure water systems to cell culture and media preparation. The PURELAB Option-S series produces better than single-distilled quality, whilst the PURELAB Option-R and E series produce better than double-distilled quality. The E series is particularly cost-effective for higher volume needs and in areas where the water has a high dissolved solids content. - PURELAB Option-S - PURELAB Option-R - PURELAB Option-E
