A syringe filter (or wheel filter) is a single-use, membrane-based device used for the removal of particulate impurities from small (≤ 100 mL) liquid samples ( Figure 1 ). Selected based upon the desired end application, disposable syringe filters are commonly used in labs for fast and efficient filtering, material purification, or even
Sep 28, 2016 · The majority of syringe filters used do not allow you to reclaim the solid. They are often used before analysis to remove any solid, undissolved, material. Other, filter holder (in-line) types allow you to regain your filter (Figure 1). Syringe filters normally use membrane type filters which have a specific particle size cut off (e.g. 0.45 μm).
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
