Meissner

What Meissner does

Meissner Filtration Products, Inc., founded in 1984 and headquartered in Camarillo, California, is a privately held manufacturer of advanced microfiltration products and integrated single-use fluid management systems for critical applications. The company's technology portfolio spans proprietary membrane filter chemistries (SteriLUX PVDF, STyLUX and EverLUX PES, Steridyne hydrophobic PVDF, Ultradyne PTFE) covering absolute ratings from 0.04 µm to 99 µm, microfiber and depth filters (Protec, ALpHA, DeltaMax, DeltaDepth, Duraclear), SepraPor hollow-fiber tangential flow filters, and the One-Touch® single-use systems portfolio including TepoFlex/XytoFlex/FlexGro biocontainers, BioFlex/M-Flex/M-Sil tubing, BioLink modular overmolding, and rigid outer containers (FlexStation, QuaDrum). Capital equipment offerings include the CryoVault freeze/thaw platform (deployed at over 20 global sites), Saltus CFD-optimized single-use mixing system, AccuFill aseptic filling systems, and AccuFlux filter integrity testers, all manufactured in automated world-class cleanrooms in California and Ireland.

The company generates revenue primarily through direct technical sales of consumables (filters, single-use assemblies) and capital equipment, supplemented by Meissner Technical Services (MTS) providing validation, SEM/X-ray analysis, and training. Pricing is quote-based and tailored to customer specifications rather than list-published. Meissner serves biopharmaceutical and pharmaceutical manufacturers as its primary segment, with additional exposure to microelectronics (photolithography, CMP, wet etch, gas delivery), food and beverage, general chemical, and printing/graphic arts. The go-to-market model is enterprise field sales with cross-functional engineering teams working directly with clients at multiple organizational levels, supported by wholly-owned subsidiaries in Ireland (manufacturing), Germany, Italy, and Switzerland (sales), plus active participation in industry events including CPHI, INTERPHEX, PDA, ISPE, BPOG, and ASGCT. The company is independently owned with no disclosed parent, venture capital, or private equity investors, and recently committed $250 million to a new Athens, Georgia manufacturing facility announced in June 2024.
