Single-use vials are ideal for air shipment of small-volume reagents and for many diagnostic kit applications.

High-purity, low metal-content polypropylene copolymer (PPCO) resin is ideal for PCR reagents. Vials can be centrifuged to 13000 g at room temperature. Precise external dimensions for smooth, jam-free automated filling. Leakproof, threaded screw closures have no O-ring to fall out or contaminate contents. Vials and closures are noncytotoxic and nonpyrogenic. The 11 mm closures fit the 0.5, 1.5, and 2 ml vials. The 13 mm closures fit the 4.5 ml vials. Vials 73521-158 and 73521-160 are sterilized using electron beam irradiation.
