The holder has a well supported by a sidewall of the holder and open at a first end thereof for receiving therein a tube body of a micro tube. The mounting sleeve is attached on and along the sidewall of the holder. The lifting bar is slidably mounted by and through the mounting sleeve to undergo movement between a retracted position and an extended position. A first end of the lifting bar in the retracted position is disposed adjacent to the first end of the holder and adjacent to a cap of the micro tube in a closed position interference fitted into the tube body of the micro tube when the tube body of the micro tube is disposed within the well of the holder. The first end of the lifting bar in the extended position is disposed outwardly from the first end of the holder such that the cap of the micro tube is forced into an open position in response to engagement of the lifting bar therewith upon movement of the lifting bar from the retracted to extended position.
