Abstract
A testing apparatus in which a vacuum holder mounted on a carrier is used to hold a specimen on the carrier as the carrier is moved from a first location to another location where the specimen is deposited can be modified so that the vacuum supplied to the vacuum holder is used to actuate a pump so as to dispense a predetermined quantity of fluid each time the carrier is in such another location. Such a modified apparatus can be utilized in medical testing in dispensing a reagent into an appropriate receptacle such as a test tube serving as a receiving means for the specimen. Such a structure is advantageous because it utilizes a single vacuum source for both holding a specimen on a carrier and for dispensing a liquid.
