Cytiva : What floorutions for sampling, filtration and purification in the laboratory?

A global reference brand, Cytiva supports research and bioproduction with dependable solutions, from sampling through to purification. Its flagship lines — Whatman (filtration) and Amersham (Western blotting) — deliver reproducible results in R&D, quality control and process development. Traceability, lot-to-lot consistency and comprehensive documentation slot seamlessly into modern lab workflows. Dutscher supplies a carefully curated selection of the most widely used consumables for everyday lab work.

A strong heritage: a brand launched in 2020

Spun out of GE Healthcare Life Sciences in 2020, Cytiva builds on decades of innovation from Amersham and Whatman. With global headquarters in Marlborough, MA (USA) and major sites in Uppsala (Sweden) and Amersham (UK), the brand serves the biopharmaceutical, academic and industrial ecosystem. It has earned its reputation through excellence in biomolecule purification and analytical filtration, underpinned by manufacturing quality, lot-to-lot consistency and hands-on applications support. Its growth is driven by continuous portfolio expansion and by services that de-risk processes from bench to scale-up, with no compromise on compliance or reproducibility.

Expertise and areas of specialisation

Cytiva is recognised for consumables that help demanding laboratories save time and work with confidence. On the Whatman filtration side, the benchmark filter papers (e.g. Grade 1, glass microfiber GF), syringe filters (PTFE, PVDF, RC, PES) and membranes for microbiological testing cover sample preparation, HPLC/UPLC and routine QC. Mini-UniPrep devices and Unifilter microplates streamline high-throughput clarification and cut down on hands-on steps.

For bioanalysis and immunodetection, Amersham provides nitrocellulose and PVDF membranes optimised for Western blotting plus ECL reagents with a high signal-to-noise ratio, enabling reproducible sensitivity. In protein purification, prepacked HiTrap columns (His, IEX, affinity) and PD-10 desalting columns (Sephadex G-25) accelerate critical preparation and polishing steps, with proven compatibility across flow rates and buffers.

This filtration–detection–purification combination puts Cytiva at the heart of R&D, QC and upstream bioprocess workflows. What makes the daily difference: consistent media quality, full traceability (CoA, clear catalogue numbers), extensive application documentation and responsive technical support. Result: less variability, robust methods and decision-ready data sooner, from the first run through to a validated protocol.

Frequently asked questions about the Cytiva brand

Are Whatman syringe filters compatible with solvents and aqueous media?
Yes. PTFE, PVDF, RC or PES membranes cover most solvents, buffers and biological samples. The choice depends on polarity and the target analytes.

Can HiTrap and PD-10 columns be used without an ÄKTA system?
Absolutely. They operate by gravity, syringe or peristaltic pump, with recommended flow rate ranges and detailed user guides.

What do Amersham PVDF membranes offer versus nitrocellulose in Western blotting?
PVDF provides high retention and robustness, useful for low-abundance proteins. Nitrocellulose enables rapid blocking and clean transfers for general use.

How does Cytiva ensure lot to lot consistency and traceability?
Each lot is quality controlled and supplied with a CoA/lot number. Standardised specifications and test methods stabilise performance across supplies.

Are there concrete CSR initiatives for consumables?
The brand is working on eco-design, packaging reduction and clear supply chain documentation, to reduce the footprint without compromising quality.
