Waters ptfe 0.45 micron filter for sterilization

Jul 28, 2015 · When we perform sterility testing we use 0.45 micron filter but when we prepare and filter the disinfectant solution we use 0.22 micron filter. During batch preparation of SVP, LVP and liquid injections we also use 0.22 micron pore size filter for filtration of batch. The reason behind these questions is the purpose of using these filters.

be performed using a 0.1 µm pore filter. Routine labora tory sterilization of most media, buffers, biological fluids and gases is usually done with 0.2 or 0.22 µm pore filter membranes. Clarification and prefiltration of solutions and solvents is best accomplished with 0.45 µm or larger filter membranes.

Tissue culture media sterilization ; PTFE (Teflon®) PTFE (Teflon®) polytetrafluoroethylene membrane consists of a pure PTFE laminated to a polypropylene support for improved durability and easy handling. These filters are chemically compatible with strong acids and most aggressive solvents such as alcohols.
