Glass and aluminum vials are extensively used in the pharmaceutical industry to store medication in liquid or powder form; additionally they find application in labs to store samples. These vial capping machines are hand operated and are specifically meant for crimp type vials which are secured by a rubber stopper and metal cap. Flip-top/snap cap sealers are also available.

Handheld vial cappers are ideal tools for securing aluminum caps on glass/aluminum vials and see wide use in pharmaceutical and microbiology laboratories for testing purposes. They can also be used for small production runs providing an output of approximately 150-250 bottles per hour. The jaws are made out of heat treated steel and provide sufficient hardness to ensure wear resistance for a prolonged period of time. The main body of the vial capper is made of mild steel that is powder coated to prevent corrosion. These vial cappers are meant specifically for standard vial caps having a diameter of 20 mm.
