How To Use a Syringe Filter. Fill the syringe with the solution to be filtered. Fasten the filled syringe to the FLL inlet of the syringe filter with a twisting motion. With the outlet pointed upward, gradually apply pressure to the syringe plunger to initiate flow. Continue thumb pressure until all the air in the device is displaced with

Syringe filter - Wikipedia

A syringe filter is a single-use filter cartridge. It is attached to the end of a syringe for use. Syringe filters may have Luer lock fittings, though not universally so. The use of a needle is optional; where desired it may be fitted to the end of the syringe filter. A syringe filter generally consists of a plastic housing with a membrane that serves as a filter. The fluid to be purified may be cleaned by drawing it up the syringe through the filter, or by forcing the unfiltered fluid through t
