50 mm Critical Small Scale Filter Device
Ideal filters for removal of microorganisms and particulates from critical small batch liquid volumes from 50 mL to 2 L, and air and gas applications.
Meissner’s 50 mm critical small scale filtration device portfolio, or CB filter model line, delivers excellent performance in venting applications. However, by expanding the media options available in the 50 mm filter size to include a host of both hydrophobic and hydrophilic membranes, and Meissner’s unique gradient density prefilter media, the ideal applications for this filter device have been greatly expanded. For critical liquid or air/gas applications, we offer membrane options including hydrophilic PVDF and hydrophobic PVDF, hydrophilic PES, and hydrophobic PTFE. Our entire portfolio of 50 mm filter devices scales effortlessly into our mini capsule filters, medium capsule filters, standard capsule filters, and large capsule portfolios. Our 50 mm filter devices use the identical materials of construction as our entire capsule filter portfolio to ensure streamlined scaling without requalification or revalidation concerns.
While these filters have traditionally been referred to as “vent filters” or “50 mm filters,” Meissner’s CB product portfolio has been optimized for use in critical small scale or small volume filtration applications, delivering the same high quality, high performance, fully supported solution as larger scale filters common to typical process scale applications. Meissner recognizes that this is required for small batch and point of use filtration applications. Each filter is available 100% integrity tested and individually serialized to offer unparalleled traceability at this scale. Multiple process connection options, including hose barb and sanitary flange fittings, vent and filling bell options deliver maximum flexibility to allow this filter portfolio to cater to specific process needs.
Meissner’s CB filter portfolio is ideal for filtering small scale liquid volumes from 50 mL to 2 L. Applications for both liquids and gases include sterile filtration, sterile venting, sample preparation, process development studies, filterability testing, product compatibility and recovery trials, process screening and scaling, and prefiltration and clarification. Since the materials of construction of these filter devices is identical to our larger capsule filters, the scale-up of a process is seamless as clients transition to larger process volumes. The 50 mm filters are available sterile (gamma irradiated), or non-sterile, and also can be integrated into our One-Touch® portfolio of single-use processing solutions.
Our Steridyne® capsule filters are an industry preferred option for single-use bioreactor venting applications to maintain a closed system. The Steridyne® CB filter device offers the same level of high performance for smaller single-use and multi-use bioreactor venting with the Ultradyne® filter option being available for multi-use bioreactor applications, as well.

Frequently Asked Questions
What is the 50 mm Critical Small Scale Filter Device?
The 50 mm Critical Small Scale Filter Device, part of Meissner’s CB filter portfolio, is a 50 mm filter optimized for critical small scale and small volume filtration. Earlier these filters were often called vent filters or 50 mm filters. They deliver the same quality and support as larger process-scale filters.
What applications is the 50 mm Critical Small Scale Filter Device used for?
The CB filter portfolio is designed for filtering small liquid volumes from 50 mL to 2 L. It is used for sterile filtration, sterile venting, sample preparation, process development studies, filterability testing, product compatibility and recovery trials, process screening and scaling, prefiltration, and clarification.
Can the 50 mm filters be used for bioreactor venting?
Yes. The Steridyne® CB filter provides venting for single-use and multi-use bioreactors and helps maintain a closed system. The Ultradyne® membrane option is also available for multi-use bioreactor venting.
How can I buy 50 mm filters?
To purchase 50 mm filters, visit the online store. For large orders, contact a Meissner representative.
What specifications are available for the 50 mm Critical Small Scale Filter Device?
Membrane options include hydrophilic PVDF (SteriLUX®), hydrophobic PVDF (Steridyne®), hydrophilic PES (EverLUX®), and hydrophobic PTFE (Ultradyne®). Each filter is 100% integrity tested and individually serialized. The filters are available sterile (gamma irradiated) or non-sterile.
What makes the 50 mm Critical Small Scale Filter Device unique?
The CB portfolio includes both hydrophobic and hydrophilic membranes and Meissner’s gradient density prefilter media. The filters use the same materials of construction as Meissner’s capsule filter portfolio, which supports scale-up without requalification or revalidation concerns.
How does the 50 mm Critical Small Scale Filter Device integrate with other systems?
Process connections include hose barb and sanitary flange fittings, and vent and filling bell options are available. The filters can be integrated into Meissner’s One-Touch® portfolio of single-use processing solutions.
Are the 50 mm filters suitable for regulated biopharmaceutical manufacturing?
The 50 mm filters are built from the same materials as Meissner’s capsule filters, and they are available sterile or non-sterile. Confirm the regulatory and validation requirements for your process with Meissner before use.
What other products are commonly used with the 50 mm Critical Small Scale Filter Device?
The 50 mm filters scale directly into mini capsule filters, medium capsule filters, standard capsule filters, and the UltraCap® H.D. large capsule portfolio. For single-use system integration, see the One-Touch® portfolio.
