Sartoclear Dynamics® Lab P15 has been designed for both clarification and sterile filtration of up to 15 mL mammalian cell culture solutions in one step. This convenient kit combines a syringe pre-filled with a filter aid for clarification and an integrated 0.2 µm polyethersulfone filter for sterile filtration. The 20 mL syringe, pre-filled with 0.5 g DE, eliminates the need for an additional centrifugation step for clarifying your cell culture solution at the harvest step prior to sterile filtration. As a result, your clarified cell culture liquid will be available faster for subsequent sample concentration by ultrafiltration and downstream analytics. The sterile filter included in the kit contains a 0.2 µm polyethersulfone membrane and a prefilter made of 100 % high-purity quartz: The choice of these materials, along with the larger surface area of the filter, enables higher flow rates. The filter is individually packaged and sterile. Technical Data
