Pre-sterilized PES Membrane Syringe Filters

mdi PES membrane type SYPL-S have Polyethersulfone (PES) membrane filter in a poly-propylene housing. These syringe filters are used for filtration and sterilization of protein solutions, culture media and serum. The low protein binding characteristics make these ideal for these applications, particularly where sample size is very small and recovery of protein of interest is sought.

  • Absolute Retention
  • Low protein binding
  • 16 Channels for minimum back pressure
  • High throughputs
  • Sterilization of high value additives such as hormones, vitamins and antibiotics.
  • Sterilization of protein solutions, culture media and buffers
