A manual device, with one-handed operation, the Manual Single Tube Picker incorporates an eject button enabling tube pick and place operations whilst avoiding contact between the hand and tube. Minimizes the risk of heat transfer to a frozen sample, as well as minimizing the risk of possible cross contamination. Simple to use, even when wearing laboratory or cryogenic-handling gloves, the tube picker is available in either 96-rack or 48-rack format.
