Whatman Autovial Syringless filters replace syringe-coupled filtration devices with a single, convenient disposable unit.

Fill your sample or solution into the barrel, insert plunger, and compress the unit to filter your sample. Ideal for filtering directly into any number of media: beakers, vials, auto-sampler, and the unit has a luer slip port protected by the plastic housing for filtering into tubing as well. Comes in .45 and .2 Nylon membranes, sterile and unsterile units available.
