DWK Wheaton Liquid Scintillation Vials 20 ml Case of 100 Vials

DWK Life Sciences Wheaton HDPE Liquid Scintillation Vials – 20 mL, High-Density Polyethylene, 22-400 White Polypropylene Cap, Attached Foamed PE Liner, Non-Sterile (MPN: 986700)

The DWK Life Sciences Wheaton 986700 (also cataloged as 986700 / 03-341-72) is a premium, research-grade liquid scintillation vial assembly engineered to provide uniform, high-efficiency beta radiation counting and secure chemical containment. Molded to precise mechanical tolerances from high-purity virgin high-density polyethylene (HDPE), these 20 mL vials feature lightweight, ultra-thin walls that maximize ultraviolet and light transmission while drastically reducing background noise counts. Each vial arrives pre-assembled with a white 22-400 threaded polypropylene screw cap fitted with a resilient, foamed polyethylene (PE) liner. This multi-layer elastomeric lining creates a tight hermetic seal that actively resists chemical attack from aggressive scintillation cocktails, alcohols, acids, and alkalis, preventing hazardous fume escape and concentration drift during high-throughput counting runs.

Technical Performance and Design

• Lightweight High-Efficiency HDPE Matrix: Fabricated from specialty high-density polyethylene characterized by ultra-low background interference and high UV transparency. The engineered thin-wall structural geometry allows beta particle emissions to interact cleanly with counting fluids, boosting signal detection efficiency.

• Foamed PE Lined Polypropylene Closures: Outfitted with a 22-400 threaded white polypropylene screw cap lined with a compressed foamed polyethylene disc. This liner exhibits outstanding environmental immunity, blocking leaks when exposed to organic solvents, aqueous samples, household cosmetics, and household chemical groups.

• Jam-Free Dimensional Engineering: Manufactured to rigid automated tolerances ensuring a highly uniform outer profile (27 mm diameter x 61 mm height with cap attached). This absolute geometric precision prevents the vials from hanging up, jamming, or cracking inside complex robotic beta counter loader lines.

• Contamination-Barred Utility Trays: Shipped pre-arranged in clean cardboard utility trays with individual partitioned cells that securely anchor 100 vials per layer. The entire tray is factory shrink-wrapped in protective plastic film to shield the stock from warehouse dust, grease, and atmospheric particulates before bench introduction.

Key Benefits and Applications

• Liquid Scintillation Counting (LSC): The standard industry consumable selection for conducting routine radioisotope assays, metabolic tracking, environmental radiation screening, and low-energy beta particle quantifications (such as Tritium H-3 and Carbon-14).

• Eco-Forward Laboratory Incineration: Clean-burning HDPE and polypropylene chemical composition allows these vials to be safely incinerated post-assay without emitting hazardous chlorinated gas byproducts or heavy ash residues, slashing biohazard waste overhead.

• Trace Sample Compound Archiving: Naturally hydrophobic plastic walls minimize sample-to-surface protein binding and ion absorption, making them excellent secondary containment choices for dilute biological reagents and analytical standards.

• Dual-Purpose Storage Trays: The included heavy-duty partitioned cardboard trays serve as highly stable benchtop processing racks and organized archival archiving templates inside chemical safety cabinets.
