Product description

Strongly basic Dowex 1X8 anion-exchange resin, 100-200 mesh beads for efficient laboratory anion separation and purification.

The Acros Organics Dowex 1X8 ion-exchange resin is a strongly basic anion-exchange medium designed for high-efficiency laboratory separation and purification processes. Manufactured from a polystyrene-divinylbenzene matrix, it features quaternary ammonium functional groups that enable rapid exchange kinetics and high surface area for effective ion-exchange performance.

Key technical specifications include:

  • Particle Size: 100-200 mesh, providing optimal surface area for fast ion exchange applications
  • Physical Form: Tan to white beads with typical chloride (Cl⁻) form
  • Total Ion Exchange Capacity: Greater than 1.2 meq/mL, suitable for demanding biochemical purification workflows
  • Water Retention Capacity: 39-45%, ensuring stable hydration and ion accessibility
  • Molecular Formula: C29H34ClN
  • CAS Number: 12627-85-9

This resin is widely employed in analytical ion-exchange chromatography, anion separation protocols, and purification methods crucial in biotechnology, molecular diagnostics, and bioprocessing. Its utility extends to synthetic biology research and biopharmaceutical production pipelines requiring precise ion-exchange performance.

Applications:

  • Separation of diverse anionic species in biochemical samples
  • Purification of biomolecules in molecular cloning and synthetic biology workflows
  • Analytical ion-exchange for clinical diagnostics and biomanufacturing quality control

The Dowex 1X8 resin's bead format and controlled mesh size facilitate consistent flow properties and column packing efficiency, making it a reliable component in laboratory-scale ion exchange systems and preparative bioprocessing operations.

This ion-exchange resin aligns with industry standards for polymer-based ion-exchangers (Harmonized Code 391400) and supports robust, reproducible separations in research and applied biotechnology settings.

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.
