Abstract
A laboratory mixer for mixing a sample and a diluent in a bag. An enclosure defines a mixing chamber, and at least one movable mixing element is retained for mixing the sample and the diluent within the bag. At least one liquid detector is retained relative to the enclosure for detecting liquid leaked from the bag. The sensor can be a capacitive, inductive, or optical sensor. The sensor can be a conductivity sensor with two electrodes shaped like combs and a gap less than or equal to a diameter of a drip of diluent solution. A ledge with a low point can be retained by an access door. The sensor or sensors can be disposed adjacent to the access door, on a mixing element, in direct contact with the bag, or on a tank. An alarm and cessation of operation can be triggered upon a detection of leaked liquid.
