Cobetter Filtration — Global Source for Lab & Bioprocess Filters

Founded in 2003 and headquartered in Hangzhou, China, Cobetter is a globally recognized manufacturer specializing in filtration, separation, and purification solutions for the biopharmaceutical and laboratory industries. Built on a foundation of membrane material research and development, Cobetter has grown from a seven-person startup into a company with over 5,700 employees and more than 1,500 engineers worldwide.

With over 300 patented technologies and ISO 9001-certified manufacturing facilities, Cobetter serves more than 28,000 customers across 106 countries — from academic research laboratories to large-scale biopharmaceutical production sites. The company maintains subsidiaries in Shanghai, Japan, South Korea, Taiwan (China), and Singapore, enabling responsive local support alongside a globally integrated supply chain.

Cobetter's product scope spans laboratory consumables, process-scale filtration systems, single-use bioprocess technologies, and specialized virus removal filters — making it one of the few manufacturers capable of supporting a research workflow from benchtop to commercial production.

Cobetter Product Categories: From Laboratory Consumables to Large-Scale Bioprocess Filtration

Cobetter offers a comprehensive portfolio organized across laboratory and process filtration applications. Whether you are filtering small sample volumes at the bench or managing sterile filtration at pilot scale, Cobetter provides validated products for every stage.

Laboratory Filtration covers the full range of everyday consumables used in basic and life science research: syringe filters, vacuum filter units, centrifugal filters, capsule filters, vent filters, membrane filter discs, filter plates, and filter funnels. These products are manufactured in ISO Class 8 cleanrooms with consistent pore sizes and low non-specific binding across membrane types, including PES, PVDF, Nylon, PTFE, and PP.

Process Filtration addresses the more demanding requirements of biopharmaceutical manufacturing. This includes sterilizing-grade capsule and cartridge filters, depth filters for clarification and harvest, tangential flow filtration (TFF) systems for concentration and buffer exchange, and ultrafiltration modules for downstream purification. Cobetter's process filtration products are designed for linear scale-up from laboratory to production, with full validation support and regulatory documentation available.

Virus Removal Filtration is one of Cobetter's core technology areas. The Viruclear™ and Corevital® product lines provide validated solutions for viral clearance in biologics manufacturing, covering mAbs, ADCs, recombinant proteins, blood products, and cell and gene therapy applications.

Single-Use Technology includes 2D and 3D single-use bioprocess bags, ultraclean steam bags, fluid transfer assemblies, and single-use connectors — designed for liquid preparation, storage, shipping, and final fill operations with high chemical compatibility and low extractables.

Cobetter Product Brand Lines: Viruclear™, Corevital®, and BriScale®

Cobetter organizes its specialized process filtration products under distinct registered brand names, each targeting a specific application within biopharmaceutical manufacturing.

Viruclear™ — Virus Removal Filters for Biologics Purification

Viruclear is Cobetter's primary virus removal filter line, covering both PES and RC membrane options to address a broad range of protein substrates and process requirements. The Viruclear VF and VF Plus series use an optimized composite PES membrane with asymmetric structure and surface hydrophilic modification, offering high mass capacity and strong virus retention for mAbs, ADCs, bispecific antibodies, and recombinant proteins. The Viruclear RC and RC H series use regenerated cellulose membranes with naturally high hydrophilicity, making them particularly suited for high-concentration, high-viscosity plasma-derived products such as IVIG and coagulation factors — applications where PES membranes face flux limitations. Viruclear syringe filters are used for process development and virus clearance validation at laboratory scale, while cassette and capsule formats support pilot and production-scale operations.

Corevital® — Sterilizing-Grade Prefiltration for Virus Removal Workflows

The Corevital product line provides sterilizing-grade and prefiltration solutions designed to be used upstream of virus-retentive membranes. Corevital SMD and SMDA filters use hydrophilic PVDF membrane with low protein adsorption and high flux, protecting downstream virus removal membranes from premature fouling. These filters are validated for use in blood product manufacturing workflows, including factor IX and IVIG production.

BriScale® — Scalable Bioprocess Filtration Solutions

BriScale is Cobetter's registered brand for scalable single-use filtration assemblies, designed to ensure process consistency and material traceability across scale-up stages from lab to pilot to commercial production.

Cobetter Applications: Biopharmaceutical Manufacturing, Cell Therapy, Blood Products & Laboratory Research

Cobetter products are validated for use across a broad range of research and manufacturing applications.

In biopharmaceutical manufacturing, Cobetter supports the full downstream purification workflow for mAbs and ADCs — from upstream medium filtration and cell harvest clarification through chromatography pre- and post-filtration, virus removal, TFF concentration, and final sterile filtration. For mRNA and vaccine production, Cobetter offers filtration solutions compatible with lipid nanoparticle (LNP) formulations and other sensitive modalities. In cell and gene therapy, the product range addresses the unique requirements of viral vector manufacturing, including clarification, ultrafiltration, and sterile filtration of concentrated viral preparations.

For blood products, the Viruclear RC and RC H filters, used in combination with Corevital prefiltration products, are designed specifically for the high-viscosity, high-concentration protein matrices found in IVIG, albumin, and coagulation factor manufacturing.

In the laboratory, Cobetter's syringe filters, vacuum filter units, and centrifugal filters support routine research tasks including sample clarification before HPLC/GC analysis, sterile filtration of cell culture media and reagents, protein concentration and buffer exchange, and particle removal for analytical assays.
