The 4 ml polyethylene scintillation vial uses a full turn polyethylene screw cap.

The 6.5 ml scintillation vial is securely sealed by simply snapping the caps on. The cap is conveniently removed with an easy quarter turn to the left.

The 20 ml scintillation vial has multiple uses in scintillation counting, gamma counting, chromatography, sample storage and culturing. Because of its leak-tight cap, it is also commonly used to store and transport histological specimens in 10% formalin. This scintillation vial provides a high degree of resistance to organic solvents and sufficient translucence, so reagent levels can be easily seen. The unique thread design of the closure permits the vial to be sealed tight with an easy quarter turn and minimum pressure.

This small volume scintillation vial is the most economical size to use because it requires the least amount of solvent.
