Product description

High-capacity Dowex 50WX8 sulfonic acid cation-exchange resin with 100-200 mesh for precise analytical separations.

The Acros Organics Dowex 50WX8 is a high-capacity, strong acid cation exchange resin designed specifically for analytical separation and sample preparation applications. It features sulfonic acid functional groups, facilitating efficient cation exchange critical in biochemical and chemical processing workflows. The resin is presented as moist beads or spheres with a particle size distribution of 100-200 mesh, ensuring precision in separation tasks commonly required in molecular diagnostics and bioprocessing.

Key technical specifications include:

  • Total wet volume capacity: minimum 1.7 meq/mL in H form, supporting reliable ion exchange performance.
  • Water retention: 50-58%, maintaining bead stability during use in aqueous solutions.
  • Physical form: moist beads or spheres, beige to brown in color, stable and insoluble in water.
  • Packaging: supplied in a 2.5 kg plastic bottle for ease of handling and storage.
  • Particle size tolerance: maximum 15% through 170 mesh, suitable for fine chemical separations in analytical laboratories.
  • CAS Number: 11119-67-8, facilitating research compliance and chemical cataloging.
  • Country of Origin: United States.

Widely used in biotechnology research fields such as synthetic biology, molecular cloning, and biomanufacturing, this resin plays a critical role in deionization, purification, and separation processes integral to molecular diagnostics and biopharmaceutical production pipelines. The consistency and high capacity of Dowex 50WX8 make it essential for laboratory protocols requiring reproducible ion exchange performance.

This ion-exchange resin is ideal for laboratories specializing in biomedical engineering, clinical diagnostics, and chemical analysis, and it supports applications demanding precise cation separation and high-efficiency resin performance. Its compatibility with aqueous systems and robust ion exchange capacity render it popular among scientists focused on live-cell imaging sample prep, fluorescence analysis, and neurochemistry studies.

Overall, the Dowex 50WX8 resin ensures stable, efficient chemical separation critical for advanced analytical applications and high-throughput bioprocess workflows.

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.
