Cytiva

Cytiva is a US life-sciences company based in Marlborough, Massachusetts, that builds equipment and consumables for biopharmaceutical research and production, from the lab bench to GMP manufacturing scale. Its line-up includes single-use bioreactors, chromatography systems with their resins, filtration for both laboratory and bioprocess work, cell-culture media and instruments for biomolecular analysis.

ZHIMAI, a China-based supplier, provides Cytiva equipment and spare parts to life-science and biopharma sites worldwide, drawing on direct access to manufacturers across China, Asia and other markets. When a system is discontinued or hard to find, we identify the current successor and handle procurement, logistics and customs, subject to compliance screening.

Typical product lines we supply:

• ÄKTA chromatography systems: liquid chromatography instruments (ÄKTA pure, start, avant, process) for purification of proteins, peptides and nucleic acids from lab to GMP scale.
• Chromatography resins and columns: separation media including Sephadex, MabSelect PrismA affinity, ion-exchange and gel-filtration resins, plus prepacked HiTrap and AxiChrom columns.
• Whatman laboratory filtration: cellulose and glass-microfiber filter papers, membrane filters, syringe and capsule filters for sample preparation and analytical work.
• Bioprocess filtration (TFF and sterile/virus filters): tangential flow filtration cassettes and skids, hollow-fiber and depth filters, sterile/virus/air-gas filters with integrity-testing instruments.
• Single-use bioreactors: Xcellerex stirred-tank (XDR) and Xuri/WAVE rocking bioreactors with mixers and disposable flow paths for upstream cell culture and fermentation.
• Biacore SPR analysis systems: surface plasmon resonance instruments and consumables for label-free analysis of binding affinity and kinetics.

Whether the item is in current production or long discontinued, we can source the Cytiva equipment, subject to compliance screening.
