Review: Excelente producto. - Buen producto, muy recomendable. ## Features - Manufactured from low-potassium 3.3 borosilicate glass, compliant with ASTM E438 Type I, Class A and USP I standards. With a thermal expansion coefficient of 3.3×10⁻⁶/°C, it delivers exceptional thermal stability, chemical resistance, and withstands up to 330°C. The low-potassium formulation minimizes background counts, ensuring accurate, reliable scintillation results for critical research. - Low Background Design for Accurate: CountingLow-potassium 3.3 borosilicate glass reduces background radiation interference during scintillation counting, ensuring higher counting efficiency and more reliable data. Ideal for environmental tritium monitoring, radiocarbon dating, and low-level radiation research. - Leak-Proof Sealing- Ideal for Long-Term Storage & Transport: Equipped with GPI 22 400 white PP solid caps and silver aluminum foil PE liners for superior leak-proof sealing. The foil layer offers extremely low moisture/gas permeability, maintaining sample concentration and composition over time, reducing volatilization, oxidation, leakage, and contamination. Triple-layer (foil/PE) resists acids, bases, and organic solvents. Ensures integrity and stability during long-term storage or transport. Rigid PP caps are chemically resistant and writable for easy identification. - Optimized Wall Design for Sample Recovery: Uniformly thin walls and an ultra-smooth interior minimize sample adhesion, enabling efficient cleaning and maximum recovery. Exceptional clarity allows precise observation while uniform walls reduce light scattering to enhance counting accuracy. - Cellular trays with alphanumeric grids and protective film keep vials clean and organized. Compatible with all standard 20ml counters. Ideal for teaching, pharmaceutical, environmental, and analytical labs. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C3R3W24F | | Best Sellers Rank | #165,832 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #7 in Lab Scintillation Vials | | Bottom Shape | Round | | Brand | ALWSCI | | Brand Name | ALWSCI | | Capacity | 20 ml | | Customer Reviews | 5.0 out of 5 stars 6 Reviews | | Included Components | vials and caps | | Item Highlight | Low-potassium 3.3 borosilicate glass, Excellent light transmittance for liquid scintillation counting Item Highlight Low-potassium 3.3 borosilicate glass, Excellent light transmittance for liquid scintillation counting See more | | Manufacturer | ALWSCI | | Number of Items | 100 | | Part Number | C0002391 | | Shape | Cylinder | | Unit Count | 100 Count | ## Product Details - **Material:** Borosilicate Glass - **Capacity:** 20 Milliliters - **Brand:** ALWSCI - **Bottom Shape:** Round - **Manufacturer:** ALWSCI ## Images ![20mL Scintillation Vials, Low-Background 3.3 Borosilicate Glass, 100-Pack - Image 1](https://m.media-amazon.com/images/I/612mWweeTCL.jpg) ![20mL Scintillation Vials, Low-Background 3.3 Borosilicate Glass, 100-Pack - Image 2](https://m.media-amazon.com/images/I/71brmmv97CL.jpg) ![20mL Scintillation Vials, Low-Background 3.3 Borosilicate Glass, 100-Pack - Image 3](https://m.media-amazon.com/images/I/71MMclt8OGL.jpg) ![20mL Scintillation Vials, Low-Background 3.3 Borosilicate Glass, 100-Pack - Image 4](https://m.media-amazon.com/images/I/71RBgsWLLAL.jpg) ![20mL Scintillation Vials, Low-Background 3.3 Borosilicate Glass, 100-Pack - Image 5](https://m.media-amazon.com/images/I/61B9sIZFAGL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Muy buen producto. *by J***A on April 15, 2026* El producto cumplió con mis expectativas de calidad. ### ⭐⭐⭐⭐⭐ Excelente producto. *by J***A on February 12, 2026* Buen producto, muy recomendable. ## Frequently Bought Together - ALWSCI 20 ml Scintillation Vials Liquid Borosilicate Glass Sample Scintillation Counting Vials, 22-400 White Screw Cap, Silver Aluminum Foil Liner, Pack of 100 - Kashi Scientific 1.5mL Microcentrifuge Tube with Snap Cap [1000/Pack] 1.5 mL Centrifuge Tubes with Flip Cap, Clear Graduation, Polypropylene, Plastic Lab Snap Tubes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/553460358-20ml-scintillation-vials-low-background-3-3-borosilicate-glass-100](https://www.desertcart.sg/products/553460358-20ml-scintillation-vials-low-background-3-3-borosilicate-glass-100) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-09*
