Product description

High-capacity Dowex 50WX8 cation exchange resin with 100-200 mesh size, ideal for analytical separations and deionization.

The Acros Organics Dowex 50WX8 ion-exchange resin (model 335340025) is a strong acid cation exchange resin widely used in analytical chemistry, biotechnology, and molecular diagnostics. It features sulfonic acid groups for efficient and selective cation exchange, making it essential for sample preparation, chromatographic separations, and deionization processes.

  • Physical form: Moist beads/spheres, beige to brown color
  • Particle size: 100-200 mesh (max 15% on 60 mesh, max 15% through 170 mesh)
  • Capacity: Total exchange capacity of 1.7 meq/mL (H⁺ form)
  • Water retention: 50-58% moisture content
  • Chemical identifiers: CAS 11119-67-8, MDL MFCD00132726, IUPAC AmberChrom 50WX8
  • Packaging: 2.5 kg in plastic bottle
  • Solubility: Insoluble in water

This resin’s high cation exchange capacity and mesh size enhance its application in bioprocessing workflows, synthetic biology research, and biomanufacturing production pipelines that require precise ion separation and deionization. Dowex 50WX8 resin is critical in preparing samples for molecular cloning, gene editing experiments, and biomedical engineering applications demanding consistent ionic purity.

Its durable polymer matrix ensures longevity and reproducibility in chromatographic applications such as ion-exchange chromatography and water treatment in clinical and research laboratories. This product complies with harmonized code 3914.00.00, confirming its classification as a primary form polymer-based ion-exchanger.

Using Dowex 50WX8 resin supports researchers and lab professionals in obtaining high-purity biological and chemical samples, making it highly sought after in fluorescence analysis, cell imaging sample prep, and other biotechnology-driven research areas.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
