Product description

High-capacity 8% cross-linked strong acid cation exchange resin (200-400 mesh) for chromatography and biochemical separations.

The Thermo Scientific Dowex 50WX8 is a high-performance strong acid cation exchange resin optimized for ion exchange chromatography and low-pressure liquid chromatography (LPLC) used extensively in molecular diagnostics, biochemical separations, and water deionization applications. This resin is supplied as white to off-white beads with a fine 200-400 mesh size, suitable for small-volume sample purification and high-resolution separations critical in biotechnology workflows including bioprocessing and synthetic biology research.

  • Functional group: Sulfonic acid (-SO3H) enabling efficient proton exchange
  • Matrix: Styrene-divinylbenzene gel with 8% crosslinking for enhanced mechanical stability and chemical durability
  • Exchange Capacity: Approximately 1.1 meq/mL (wetted bed volume) ideal for catalysis and resin-based synthesis
  • Physical form: Beads with 50-58% moisture content, ensuring optimal swelling and ion-exchange efficiency
  • Recommended applications: Ion exchange chromatography, LPLC, biochemical separation, water softening, resin synthesis, molecular biology purification steps
  • Storage: Store sealed in dry conditions at ambient temperature to maintain resin integrity

This resin is a critical reagent for molecular biology researchers, biopharmaceutical production pipelines, and clinical diagnostics requiring reliable, high-capacity ion exchange materials. Its fine mesh enables precise fractionation essential in gene editing workflows and biomanufacturing environments, making it a staple in modern biotechnology laboratories.

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.
