Product Description
Keep scintillation samples sealed and clearly identified with a closure designed specifically for counting vials. The flat top accepts marker labels or handwriting, so sample identification stays on the cap even when vials are packed tightly in counter racks, and the cap material holds up to the strong oxidizing mixtures common in sample preparation.
This listing is for Kimble catalog number 74521-15425: White Polypropylene Closures, 15-425, Case of 1,000. Each closure is molded from white polypropylene with a closed top. The 22-400 version carries a pulp-backed aluminum foil liner that provides a barrier between sample and cap. Two thread finishes are offered, 15-425 and 22-400, to match common scintillation vial necks. These closures are not autoclavable and are packed in cases of 1000. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
