Ultra pure water (Type I) and pure water (Type II) is a vital resource for every scientific application. The CRYSTA Series is a line of lab water purification systems that will deliver the best technical results for your lab water purification needs from general pure lab water use in buffer preparation and high purity glassware rinsing to critical use in High Performance Liquid Chromatography (HPLC) and Polymerase Chain Reactions (PCR). The CRYSTA pure water filtration systems produce highly purified water at a reliable, efficient and robust rate that meets the American Standard for Testing & Materials water purity specifications. The CRYSTA Series also surpasses the Clinical & Laboratory Standards Institute specifications for Type 1 water and Type 2 water resistivity levels. It accomplishes this by using a unique network of filtration mechanisms to maximize water resistivity and yield low total organic carbon concentrations.
