What Bio-Link does

Bio-Link (百林科) is a Shanghai-headquartered, privately-held Chinese bioprocess equipment and consumables supplier founded in 2015, with five production bases across China (Shanghai, Suzhou, Nantong, Lanzhou) totaling 46,000 sqm and 500+ employees. The company offers an integrated portfolio spanning upstream cell culture (CytoLinX® bioreactors in 50L to 2,000L scales, cell culture bags, Puredex® Cyto-1 microcarriers), fluid management (BioHub® storage and mixing bags, SynaLinX® platinum-cured silicone tubing, sterile sealers and welders), downstream chromatography purification (Chrom-LinX® columns, VERDOT Ips² InPlace™ industrial columns under distribution, MaXtar® / Chromstar® / ChromaX® chromatography media), process filtration (FiltraLinX® ultrafiltration and Cernolix®/VentiLink®/Puruflon® filters), and hydration products (HydroLinX®). The Lanzhou dual-base chromatography media capacity totals 120,000 liters per year, with Phase II opened in June 2023 at 85-90% automation, and the Nantong base produces up to 2 million single-use consumables and 10 million injection molds annually.

The company's core technology differentiators include proprietary Protein A variants (MaXtar ARPA) with complete IP and freedom-to-operate clearance that retain more than 90% of dynamic binding capacity after more than 200 cycles of 0.5M NaOH clean-in-place, MaXtar S HC high-capacity strong cation exchange resin with 2x dynamic binding capacity versus prior generations, MaXtar COLL multimodal resins for virus and VLP purification in flow-through mode, and ULDPE membrane chemistry for ADC-compatible single-use systems. Bio-Link maintains more than 1,000 validation documents covering ISO 9001:2015, ISO 13485, FDA DMF Type III on BioHub storage bottles, 21 CFR Part 11, USP Class VI, and ISO 10993, supported by a CNAS-certified in-house verification center.

Bio-Link operates a B2B enterprise direct-sales model with quote-based pricing, multi-year contracts, and dedicated sales teams in eight Chinese cities plus subsidiaries in Frankfurt and Singapore. Its customer base spans monoclonal antibody manufacturers, ADC developers, vaccine producers, cell and gene therapy companies, and veterinary vaccine manufacturers, with named adopters including Weikesi Biological (疫苗) and references to Fosun Henlius. The company distributes via direct field sales, major industry exhibitions (CPHI, INTERPHEX, BPD), and a co-organized 'Smart Walk' roadshow series run with 蒲公英 Ouryao. Bio-Link has raised more than RMB 1 billion across 2023-2024 rounds, including a February 2024 Series B with Asymchem Laboratories (Tianjin), Sino Biological, and Cathay Capital participation, and a November 2024 follow-on led by Cathay Capital with Shenzhen Capital Group.

Broad incumbents

• Cytiva: Global market leader in bioprocess equipment and consumables (formerly GE Healthcare Life Sciences), offering bioreactors, single-use systems, chromatography media, and filtration products across the same upstream-midstream-downstream value chain as Bio-Link. The principal international competitor Bio-Link is positioning to displace in China.
• Merck KGaA (MilliporeSigma): Life Science arm of Merck KGaA, offering Mobius bioreactors, chromatography media (Eshmuno, ProSep), single-use assemblies, filters, and buffers. Competes directly with Bio-Link across nearly the entire bioprocess portfolio and is one of the established incumbents Bio-Link is domestic-substituting.
• Thermo Fisher Scientific: Major global supplier of bioprocess products including HyPerforma bioreactors, single-use systems, chromatography resins (POROS), and process filtration. Its broad portfolio and deep pharma customer relationships make it a key international competitor to Bio-Link's full-chain offering.
• Agilent Technologies: Supplies Bio-Monolith, MabPac, and other biocolumns plus CrossLab biopharma services. Overlaps with Bio-Link's chromatography hardware and resin business, particularly in analytical and process chromatography for biologics.
• Sartorius AG: German multinational supplying bioprocess solutions including single-use bioreactors (BIOSTAT), filtration, fluid management, and cell culture media to biopharma manufacturers globally. Direct overlap with Bio-Link's upstream and fluid management portfolios makes it a primary competitor in the China market.
• Asahi Kasei (Bioprocess): Japan conglomerate with a bioprocess division offering Planova virus filters, hollow-fiber TFF systems, and process chromatography media. Comparable as an established Asia-headquartered supplier of process filtration and downstream consumables, competing with Bio-Link's FiltraLinX and Cernolix/VentiLink lines.

Direct peers

• Repligen Corporation: U.S.-based bioprocess specialist focused on single-use systems, chromatography (OPUS pre-packed columns), and filtration (Tangential Flow Filtration, XCell ATF). Highly comparable specialty bioprocess supplier with a similar focus on high-growth biopharma manufacturing workflows.
• Tosoh Bioscience: Japan-based manufacturer of chromatography resins (TOYOPEARL, TSKgel) and process media particularly strong in Protein A affinity and ion exchange. Directly comparable to Bio-Link's MaXtar and Chromstar resin product lines and a key target for displacement in Chinese mAb manufacturing.
• 东富龙 (Tofflon): Leading Chinese biopharma equipment manufacturer providing bioreactors, filling lines, freeze dryers, and increasingly single-use systems. Most direct domestic competitor to Bio-Link in upstream and downstream bioprocess equipment for Chinese biopharma customers.

Regional players

• 楚天科技 (Truking): Chinese biopharma equipment manufacturer focused on sterilization, filling, freeze-drying, and increasingly bioreactor/single-use solutions through its subsidiary Trukcell. Comparable as a domestic peer offering capital equipment into the same Chinese biopharma customer base.
