What Masterflex does

Masterflex is a global brand of peristaltic pumps and aseptic single-use fluid transfer technologies serving biomanufacturers. Its portfolio spans pumps, single-use bags, tubing, fittings, fluid measurement and control instrumentation, and custom single-use assemblies, built on an open-architecture design that lets customers mix Masterflex components with parts from other vendors. The brand claims vertical integration across pumps, bags, tubing, stoppers, and fittings, produced in ISO-certified cGMP facilities worldwide with a documented sterility validation program; sales literature cites sub-five-day turnaround on designs and validation packs.

Masterflex is operated as a brand within Avantor, Inc.'s Fluid Management solutions division and distributed exclusively through VWR, part of Avantor. The combined channel reaches more than 300,000 customer locations in 180 countries. Go-to-market is enterprise field-sales-led, pairing local single-use specialists with VWR's catalog, e-commerce, and logistics infrastructure for technical co-design of bioprocess fluid paths.

Revenue is generated through hardware sales of pumps and instruments, recurring consumables revenue from single-use fluid paths (bags, tubing, assemblies), and project-based revenue from custom bioprocess systems and skid solutions. Primary customer segments are biopharmaceutical manufacturers producing monoclonal antibodies and recombinant proteins and advanced therapy developers working on cell and gene therapies, with secondary demand from vaccine/mRNA developers and life sciences research institutions. Pricing is not publicly disclosed and Masterflex is a non-listed brand subsidiary of publicly traded Avantor.

Core offering

Masterflex designs and manufactures peristaltic pumps, tubing, fittings, single-use bioprocessing bags, and fluid transfer assemblies for biopharmaceutical and life sciences manufacturing. The portfolio operates on an open-architecture, vertically integrated model covering pumps, bags, tubing, stoppers, and fittings for upstream, downstream, and fill-finish bioprocess workflows.

Product overview

Masterflex is a brand under Avantor providing comprehensive fluid handling solutions for biomanufacturing. The portfolio is built on an open-architecture model, vertically integrated on pumps, bags, tubing, stoppers, and fittings. The core product line includes Masterflex Peristaltic Pumps and a full range of pump types (piston, gear, syringe, centrifugal, diaphragm, drum/transfer, HPLC/Gel PC, microfluidic, progressive cavity, and rotary lobe pumps). The single-use solutions portfolio comprises bioprocessing bags, fluid transfer assemblies, sampling assemblies, bioprocess filtration, storage and mixing bag assemblies, and fill-finish and drug substance assemblies. Supporting products include fluid measurement and control components (valves, flow indicators, flow switches, flow sensors, level sensors), tubing and fittings, and custom bioprocess systems. This integrated portfolio enables biomanufacturers to scale from lab to production across upstream, downstream, and fill-finish processes.

• Cole-Parmer: Cole-Parmer (an Antylia Scientific brand) sells peristaltic pumps, tubing, and laboratory fluid handling products that closely overlap with Masterflex's product portfolio, particularly for laboratory and lower-scale bioprocess customers.
• Verder Group: Verder's peristaltic pump brands (Verderflex, Verderliquids) target similar industrial and bioprocess fluid handling use cases as Masterflex, making it a directly comparable specialty pump manufacturer.

Broad incumbents

• Sartorius: Sartorius is a leading bioprocess solutions provider whose fluid management portfolio directly overlaps with Masterflex's single-use assemblies and peristaltic pump offerings, while extending into bioreactors and broader upstream/downstream platforms.
• Cytiva: Cytiva (formerly GE Healthcare Life Sciences) offers single-use fluid management solutions alongside its broader bioprocess portfolio, competing with Masterflex for biomanufacturer fluid path share across upstream, downstream, and fill-finish workflows.
• Thermo Fisher Scientific: Thermo Fisher's bioproduction and laboratory products divisions overlap with Masterflex's peristaltic pumps, single-use assemblies, and bioprocess fluid handling, while bringing much larger scale and a global direct sales footprint.
• Merck KGaA (MilliporeSigma): MilliporeSigma is a major single-use bioprocess supplier with Mobius fluid management systems that compete head-to-head with Masterflex's single-use bags, assemblies, and consumables for biomanufacturing.
• IDEX Corporation: IDEX owns multiple specialty pump and fluid handling businesses (e.g., Warren Rupp, Viking Pump) that overlap with Masterflex's broader pump portfolio beyond peristaltic technology, competing for industrial fluid handling accounts.
• Parker Hannifin: Parker's fluid handling and motion control divisions produce tubing, fittings, valves, and pumps used in bioprocess and industrial applications that overlap with parts of Masterflex's portfolio.

Emerging players

• Eppendorf: Eppendorf provides laboratory-scale pumps, bioreactors, and bioprocess consumables that compete with Masterflex's lower-volume and research-grade fluid handling products in cell culture and bioprocess development.
