Critical Process Filtration's Mini-Capsule filters, made with the same high standards and materials as our larger capsule filters deliver the performance you require and protect users from exposure to the process stream and protect fluids from environmental contaminants.
Most CPF Mini-Capsules are available pre-sterilized by gamma irradiation.
CPF Mini-Capsules are designed to provide outstanding performance and ease of use. Depending on fluid volume and application, Mini-Capsules are industrious filters intended for both lab and production environments.
Ease of Use
Mini-Capsules are devised to work in your environment so you don’t need to change your current setup or equipment. Their double-vent design enables them to be positioned in any direction or fit in tight spaces without impacting flow. Simply attach your input and output tubing according to the flow arrow and position the filter in any direction. To release air pressure, use whichever vent is most accessible. Depending on how you position the Mini-Capsule, the vents can also be used to drain the fluid.

Media Discs
Flat disc filters make testing for compatibility and efficiency simpler for researchers in early stage product development. They are well suited for pharmaceuticals, bioprocessing, industrial chemicals, solvents, water and process gases in the following applications:
- Aseptic Sampling of Fluids
- Contamination Analysis
- Particulate & Filterability Testing
- Process Scale-Up Studies
- Validation Studies
- Small Vent Filters
Disc filters are also available in a wide range of sizes for each media to fit your current disc holders.
Disc Holders
The CSH 47 mm Disc Holder is a popular size for laboratory testing.
Made from 316L stainless steel, they are true sanitary housings with no threaded vents or ports. They come with a clamp on twist valve assembly allowing for complete removal and cleaning of all components. The sanitary vent valve facilitates venting, draining, sampling, and integrity testing, and a single clamp closure enables easy disassembly and disc change out.
