D50C Disc Capsules (50mm diameter) have been specially designed for simple, quick, and efficient filtration of gases. Eight different media options can be placed in an all-polypropylene or polyethylene shell con- struction for excellent chemical, gas compatibility. The small, compact design of the filter capsule allows for su- perior air flow rate and low backpressure. Ideal for vac- uum pump protection from contamination. A hydropho- bic 1um or smaller micron size should be used for the application. It can be used as a hydrophobic barrier to protect from viral and bacterial contamination. PTFE 0.2um and PE 0.2um rated filters can be used in sterile vent applications with extremely low resistance. Gamma sterilization resistant options are available.
