Sterile filtration for cell culture media
In laboratories, maintaining the sterility of cell culture media and buffers is crucial to prevent microbial contamination, especially when working with sensitive biological samples. Sterile filtration provides a reliable method to avoid degradation caused by heat-labile biological components, eliminating the need for autoclaving.
Prevent microbial contamination in cell culture
The Millipore® Sterile Filters by Merck serve as an effective method for filtering and sterilizing cell culture media, buffers, and other biological samples. These filters offer an alternative to autoclaving, which can degrade sensitive, heat-labile components. Multiple product options are available to fit different application needs, including Stericap™ Bottle-Top Filters for fast vacuum filtration and Sterivex™ filters for pressure-driven filtration. Specific membranes like Millipore® Express® PES, Durapore® PVDF, and nylon mesh are utilized to cater to various filtration needs such as low protein binding, fast flow rates, and large particle removal. Each type of filter is designed for specific volumes, from small (50 mL) to large-scale (up to 20 L) filtration, ensuring flexibility in laboratory applications. Items like the Steripak™ filter units cater to larger-scale tissue culture media filtration without compromise on flow rate or sterility.
