Description
Hydrophilic PTFE syringe filters with a pore size of 0,22 µm and a diameter of 4 mm are compact membrane devices for laboratory syringe filtration. These non-sterile filters pair a hydrophilic polytetrafluoroethylene membrane with a small-format housing suited to low-volume sample handling. Offered as a pack of 200 pc(s), they support routine workflows in which multiple aliquots must be clarified or particulate-laden solutions prepared before analysis. The hydrophilic PTFE membrane is intended for aqueous media and many solvent systems commonly used in analytical and research laboratories, while the 4 mm format helps limit hold-up when sample quantities are restricted. The complete pack has a weight of 0,200 kg, which is practical for bench storage and inventory control. These syringe filters from manufacturer Membrane Solutions belong to standard labware for filtration and separation tasks, including sample clean-up ahead of chromatographic or spectroscopic work. The non-sterile specification suits applications where sterility is not required or where users apply their own aseptic measures. Clear pore-size and diameter identification supports method documentation and consistent filter selection across experiments and quality-control steps.

Questions about Hydrophilic PTFE syringe filters — 0,22 µm — Ø 4 mm
What is this article?
Hydrophilic PTFE syringe filters — 0,22 µm — Ø 4 mm is the article on this page. Luminix Health distributes Membrane Solutions 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.
