Millex 33 mm syringe filters offer significant performance advantages over traditional 25 mm filters, making them a fast, efficient way to prepare samples between 10 mL and 100 mL for analysis.


  • Faster flow rates with less clogging and higher burst pressure
  • Low extractables
  • Reduced sample hold-up volume
  • Color-coded for easier membrane identification
