This 11mm air-powered crimper is lightweight and easy-to-use for attaching 11mm aluminum crimp seals. It provides lab-scale or small-production-scale performance at a moderate cost, filling the gap between hand-operated machines and fully automatic equipment. This crimper operates on a standard laboratory air supply of 45 to 60psi. Bottles and aluminum seals are automatically aligned to eliminate partially crimped seals. Exhaust air is passed through the foot-operated valve so the crimper can be used inside a sterile hood. A complete unit consists of a crimper, a foot valve mounted on a base plate, and connecting tubing and fittings, all packed in a polyethylene storage case. A support stand is available separately. Required Air Supply: 45 To 60psi. Crimper Size: 11mm. Wheaton #: 224381.
