Filtration of 50 mL Samples in a Few Seconds

The Right Product for Care-Free Filtration of Small Volumes

Sartolab® RF 50 vacuum filtration units are single-use units designed for the filtration of sample volumes of up to 50 mL. They are available either with an asymmetric 0.22 or 0.45 µm polyethersulfone membrane that provides the fastest flow rates and ensures lowest protein binding as well as low extractables. The 0.22 µm version is ideal for sterile filtration of cell cultures, buffers and aqueous solutions; the 0.45 µm for clarification.

Key Benefits:

  • Highest flow rates with a large filtration surface
  • No loss of protein with low protein affinity membrane
  • Low dead volume due to optimized membrane support
  • Minimized risk of contamination with a complete ready-to-use unit
  • Designed as standalone system, or for parallel filtration of up to 6 samples with Sartolab® Multistation
