Manipulating tool

A storage and manipulating tool for replacement plunger heads (syringe tips) of the type which include a cylindrical body portion with a socket therein for receiving an attachment end of a cooperating plunger shaft and an annular flange portion of greater diameter than said body portion for sealing engagement with the precision bore of a cylinder of a metering device or the like,

• said manipulating tool having structure defining a plurality of storage cavities, each said storage cavity having a replacement plunger head disposed therein with the socket of the replacement plunger head adjacent to and facing the open end of its cavity, and elongated passage defining structure integral with said storage cavity defining structure, said elongated passage having a cross-sectional dimension that is uniform along its length and less than said annular flange portion of a replacement plunger head stored in a cavity and greater than said body portion of said stored replacement plunger head such that axial movement of a plunger shaft with an attached plunger head disposed in said elongated passage is effective to remove the attached plunger head from said plunger shaft and insertion of the exposed attachment end of the plunger shaft into a storage cavity is effective to attach a replacement plunger head to said plunger shaft for removal from said storage cavity without handling of the flange portion of the replacement plunger head attached to said plunger shaft.
