Product Description
Get a firm, consistent seal on scintillation vials with a rigid urea cap and a cone liner that centers itself into the vial neck. The cone shape presses into the opening as the cap is tightened, helping limit evaporation of counting cocktails, while the white top leaves space for sample identification.
This listing is for Kimble catalog number 74525-22400: White Urea Closures, 22-400, Case of 1,000. The cap body is molded from white urea, a hard thermoset that keeps its shape under torque. A cone-shaped polyethylene liner forms the seal. The 22-400 thread fits standard scintillation vials. These closures are not autoclavable and are designed for room temperature use. They are packed 1000 per case. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
