Description
Millex® filter units 4 mm, non-sterile, are compact syringe filter units featuring a pore size of 0,45 µm and a hydrophilic PTFE membrane. They address laboratory filtration and separation needs where a 0,45 µm pore rating and a small 4 mm format are required. The non-sterile build is appropriate when sterile filter devices are not mandated, while hydrophilic PTFE membrane construction and the defined pore size support clear material choice and protocol recording. A pack contains 100 pc(s), giving a workable quantity for day-to-day small-volume sample handling in research and analytical environments. Offered from manufacturer MERCK MILLIPORE, these Millex® units sit within standard syringe-filter labware for filtration and separation setups. Pack weight is 0,140 kg according to the product data. Laboratories can apply the units in existing filtration sequences and depend on the stated diameter, pore size, membrane type and pack size for consistent specification control.
This article is part of Syringe filters, in Filtration.

Questions about Millex®-filter units 4 mm, non-sterile, pore size 0.45µm, hydrophile PTFE membr.
What is this article?
Millex®-filter units 4 mm, non-sterile, pore size 0.45µm, hydrophile PTFE membr. is the article on this page. Luminix Health distributes MERCK MILLIPORE for laboratory use. It sits in Syringe filters, inside Filtration, in Lab consumables.
A syringe filter is a membrane in a plastic housing on a Luer fitting. Pore size, membrane polymer and diameter are the three choices. 0.2 µm is the sterilising and the HPLC-particle cut. 0.45 µm is the coarser clarification. Aqueous and solvent-resistant membranes are different polymers.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
