Unlike standard holders, the Multi-Media Pressure Sealing Filter Holder has a dual sealing system, allowing the use of a broad range of media thickness, including pads.

The unit is made of type 304 stainless steel and is supplied standard with a silicone O-Ring. The support screen is PTFE coated photoetched stainless steel. Sealing is easily achieved by hand-tightening the laterally removable locking wing nuts.

This enhanced pressure sealing system can accomodate media thickess up to 3mm without compromising the seal. Even multiple layers of media can be used in a single holder without lateral wicking.
