20 mL Scintillation Vials

20 mL Scintillation Vials Ideal for liquid scintillation counting, beta counting, isotope storage & environmental analysis Volume: 20 mL Material: PP (virgin) Temp: -20°C to 120°C Leak-proof cap 4,000 vials/carton Primary 20 mL Scintillation Vials · Liquid Scintillation Vials for LSC · Isotope Sample Vials High-Value Low Background Scintillation Vials · Beta Counting Vials · Radioactive Sample Containers · LSC Sample Vials · Scintillation Counting Vials Our 20 mL scintillation vials are engineered for precise liquid scintillation counting (LSC), offering low background, excellent photon efficiency, and consistent counting reproducibility. These vials meet the requirements of CLSI, EPA, and ASTM standards for radionuclide analysis and environmental monitoring. Whether you perform beta counting (³H, ¹⁴C) or store radioactive tracers, these vials deliver reliable performance. Why 20 mL Scintillation Vials Are Ideal for Liquid Scintillation Counting Low Background Virgin polypropylene minimizes luminescence and background counts – critical for low-level tritium and ¹⁴C detection. Photon Efficiency White vials enhance light reflection, improving counting efficiency by up to 15% compared to clear glass. Cocktail Compatibility Resistant to organic solvents (toluene, xylene, dioxane) and emulsions – no degradation or leaching. Reproducibility Precision-molded dimensions ensure consistent geometry, reducing variability across replicates. Scintillation Vials vs Glass Vials – Which One for Your LSC Workflow? Feature PP Vials (Hawach) Glass Vials Break resistance High (unbreakable) Fragile Chemical resistance Excellent (acids, bases, organics) Limited (etching by HF, strong alkalis) Background count Low (virgin PP) Very low (but variable) Cost per unit 40-60% lower Higher Disposable / reusable Designed for single use, can be washed Reusable (need thorough cleaning) Safety in radioisotope labs No shards, safe handling Risk of broken glass & contamination Verdict: For routine LSC, environmental samples, and radioactive waste, PP scintillation vials are safer, more cost-effective, and chemically robust. Glass may still be preferred for very low background applications – but Hawach also offers low-background certified PP vials upon request. White vs Transparent – Performance Comparison White vials: Maximize light reflection → higher counting efficiency. Ideal for tritium and ¹⁴C. Transparent vials: Allow visual inspection of sample color, precipitation, or phase separation – best for QC and visual checks. Both have identical chemical resistance. LSC Vial Compatibility – Works with All Major Counters Standard 20 mL dimensions (25.8 mm OD, 57 mm height) fit all liquid scintillation counters without adapters. Our vials are precision-molded to ensure smooth autosampler operation. Application Guide – Which Scintillation Vial for Your Workflow? LSC Experiments (Beta Counting) For ³H, ¹⁴C, ³²P, ³⁵S. Recommendation: White PP for maximum photon efficiency. Radioisotope Storage & Nuclear Medicine Store radiolabeled compounds, waste, or tracers. Leak-proof caps ensure safety. Environmental & EPA Testing Water, soil, air filter analysis. Low background and chemical resistance to digestion acids. Biotech / ADME / Drug Discovery Metabolic studies, receptor binding – transparent vials allow visual inspection.

Virgin polypropylene provides low background. For ultra-low-level tritium or ¹⁴C, we offer certified low-background vials (batch-tested). Contact us for specifications. Are these vials compatible with PerkinElmer Tri-Carb and Hidex counters? Yes – standard dimensions fit all major brands. We can provide compatibility certificates upon request. Can I use organic scintillation cocktails like Ultima Gold or Insta-Gel? Absolutely. PP is resistant to aromatic solvents and emulsifiers. No leaching or swelling observed. How do I clean and reuse the vials? Designed for single use, but can be washed with detergent and deionized water. For radioactive samples, we recommend disposal as per lab safety protocols. Can I get a vial that fits my specific LSC rack? We can supply dimensional drawings. Most racks accept 25.8 mm OD vials. For older instruments, contact our application engineer.
