High-capacity sulfonic acid ion exchange resin, 100-200 mesh, 2.5 kg for efficient cation exchange and analytical separations.
The Acros Organics Dowex 50WX8 100-200 mesh ion exchange resin is a high-capacity sulfonic acid-based cation exchange medium ideal for analytical separations, deionization, sample preparation, and various synthetic reaction workflows. This resin consists of moist beads or spheres with a particle size distribution ensuring 15% maximum on 60 mesh and 15% maximum through 170 mesh for consistent performance. It offers a wet volume capacity of at least 1.7 meq/mL in H form and a water retention capacity between 50% to 58%, making it highly effective in ion exchange processes. The resin exhibits insolubility in water, is beige to brown in color, and is conveniently packaged in a 2.5 kg plastic bottle, suitable for laboratory-scale bioprocessing and molecular diagnostics applications.
Key technical features include:
This resin is widely adopted in biotechnology research fields, including molecular biology, synthetic biology, and biopharmaceutical production pipelines, where precise ion exchange is critical. It is essential for molecular cloning workflows, protein purification, and biomedical engineering applications requiring robust, reproducible ion exchange performance.
The resin complies with relevant chemical standards (CAS 11119-67-8) and is produced in the United States, ensuring reliability and quality for demanding laboratory environments. The packaging dimensions and shipping weight support easy integration into routine biochemical workflows and scale-up operations in biomanufacturing contexts.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
