Meissner’s Steridyne 50 (PVDF) and Ultradyne 50 (PTFE) are multipurpose 50 mm filters for small volume venting, gas and solvent filtration. The filters are offered with stepped hose barb inlet/outlet connections.

Designed and supported for bi-directional flow, the 0.2 µm-rated filters serve as a cost-effective hydrophobic vent filter.  Additionally, the Steridyne 50 and Ultradyne 50 can be used to filter up to one liter of solvent or solvent-based liquids. When pre-wet with alcohol, the filters can be used to filter aqueous liquids.

Meissner’s 50 mm filters are designed for use in laboratory and research applications.  Steridyne 50 filters can be gamma irradiated and are ideal for venting  TepoFlex biocontainers. Both filters can also be safely autoclaved up to 30 times. Each Steridyne 50 and Ultradyne 50 filter is identified with a part number and heat stamped with a lot number.

Typical applications for the 50mm filters include sterile venting of carboys, filling vessels, fermentation tanks and bioreactors, as well as small volume filtration of aggressive solvents and aqueous solutions, when pre-wet with a low surface tension fluid.
