Abstract: A vial sealing cap opening device comprised of a body member having a channel defined therein, the sides of the channel being spaced apart a distance slightly greater than the diameter of the vial sealing caps to be opened and a blade member disposed within the channel and elevated above the back wall of the channel a distance sufficient so that the blade's tip will enter a perforation in the vial sealing cap when the vial is inserted in the channel perpendicularly to the body member and manually moved against the blade. The device further includes a vial sealing cap lift tab deformer and sealing cap ring remover.
