Move up to the advantages of Millex 33 mm syringe filters

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
