Whatman Klari-Flex™ Bottle-Top Filtration System - VWR ...

GE HealthcareComing Soon:Whatman Klari-Flex Bottle-Top Filtration SystemBringing a new level of productivity to cell culture media sterilization.Streamline your laboratory operations and improve throughputwith the new Whatman Klari-Flex bottle-top filtration system.It’s coming soon from GE Healthcare.Designed for cell culture media sterilization, the Klari-Flexsystem includes a stable, low-profile pedestal base with apermanent vacuum hose connection. This feature eliminatesa time-consuming and inconvenient step in your process –connecting and disconnecting the vacuum to each filter unit.With Klari-Flex, connect the vacuum once to the pedestalbase. Each time a new filtration unit is placed on the base,the vacuum connection is automatic.The flexible Klari-Flex system accommodates allfilter unit sizes: 250, 500 and 1000 ml.ApplicationFilter sterilization of aqueous solutions such as cell culturemedia and biological fluids.Features and benefitsImproves productivity» Permanent vacuum hose connection increases throughput» Fast connection of filter to base decreases setup time» Large 90 mm filter membrane (500 and 1000 ml units)optimizes performanceEasy to use» Drop-Connect technology requires just one handto connect unit to base» Front-facing funnel graduation marks enhance readability» Large bottle cap accommodates labeling informationMinimizes risk of spills and contamination» Weighted pedestal base is built for stability» Tapered nesting feature enables fail-safe unitplacement in base» Low profile funnel/bottle unit with wide base is tip-resistant» Ergonomically designed bottle and bottle capimprove handling
