Syringe Filter PTFE 25mm 0.45µm 100/pack vs Sterile PES Syringe Filters 0.22µm 33mm, Pack of 50

Overall winner: Sterile PES Syringe Filters 0.22µm 33mm, Pack of 50

Key Differences

Biomed Scientific's PTFE 25mm 0.45µm (Pack of 100) is more affordable and uses a chemically compatible PTFE membrane suitable for a wider range of solvents; PEKYBIO's sterile PES 0.22µm 33mm (50pcs) provides finer filtration, higher flow rates, lower protein adsorption and thermal stability but at a higher price tier and smaller pack. Choose Biomed if you need a cost-effective, chemically robust 0.45µm option in larger quantity; choose PEKYBIO if you need sterile, low-protein-binding 0.22µm PES filters and thermal stability in a smaller pack
