Frequently Asked Questions

What is included in the PureFlow vacuum filter system?

Each system includes a 0.22μm PES bottle top filter, a polystyrene receiver bottle (150mL, 250mL, 500mL, or 1000mL depending on size selected), and a sterile screw cap. Pre-assembled and gamma sterilized, the system connects directly to a vacuum source via the integrated hose barb connector.

Which pore size should I choose for my filtration application?

Select 0.22μm for sterilization-grade filtration that removes bacteria from cell culture media. Choose 0.45μm for general clarification and particle removal from buffers. Use 0.10μm for mycoplasma removal and critical ultra-fine filtration. All three pore sizes are available at LabSupplies.com.
