These syringe filters have a special hydrophilic PTFE membrane that makes it a versatile filter for aqueous samples as well as for aggressive solvents.
Low level of extractables, high flow rate and total versatility make it the most suitable filter in laboratories with filtration of both aqueous and solvent samples.
They are available in non-sterile format and in 13, 25 and 30 mm diameter.
