product description

Product Description

A premium 20 mL scintillation vial, made of low‑potassium borosilicate glass with a standard 22‑400 screw thread. These glass scintillation vials offer high optical clarity and low background counts for precise detection of beta/alpha emitters. Compatible with most of mainstream liquid scintillation counters, they can be supplied plain with a secure white polypropylene cap and foil liner—ideal for leak-free lab workflows. Packaged in trays of 100, these scint vials are essential labware for analytical and radiometric applications.

Features

High-quality borosilicate glass ensures low background radiation and robust chemical resistance
Dimensions: 28 mm Ø × 57–61 mm (with cap), 22‑400 threading
Clear visibility for sample monitoring and precise volume readings
Secure screw-cap options available with polypropylene, urea, or foil-lined liners
Autoclavable for sterilization in clean labs (glass + cap compatibility)

FAQ

Q1: Can these 20 mL scintillation vials be reused?

A1: Yes—after thorough cleaning and confirming no residual radioactivity. Check caps and liners retain full sealing efficacy

Q2: Why choose glass scintillation vials instead of plastic?
A2: Glass offers superior solvent resistance, optical transparency, and consistently low background noise. Plastic vials (HDPE, PET) are lighter, shatter-resistant, and suit field sampling .

Q3: Which cap liners are best for my application?
A3: Use polyethylene cone liners for standard organic solvents, and PTFE or foil-lined caps for aggressive or radioactive cocktails to ensure maximum containment and compatibility .

Q4: Are these vials compatible with standard LSC instruments?
A4: Yes—their 28 × 57 mm dimensions and 22‑400 threading ensure broad compatibility with major liquid scintillation counters .
