Abstract
A cap removal device is provided for a cellular sample treatment apparatus. The device avoids the necessity to manually remove a cap and allows an automated sequence of steps to be carried out. The device is utilized in an apparatus for treating samples of cellular materials wherein the samples are contained in a stack of sample holders and fit in a stack holding tube, open at the top with a removable cap. A transfer tube having a bottom opening to fit on the top of the stack holding tube is provided and has a drive system to move the stack from the stack holding tube to the transfer tube. The improvement includes a fork attached to the drive system for the stack removal, and a button or grooved member on the cap for engagement by the fork so that when the drive system moves upwards it lifts the cap with it.
