Unlike the bi-tube damper, the mono-tube shock has no reservoir tube.

The apparatus (1) has a wand (2) and a reservoir tube (6).

The cap (5) of the wand securely and sealingly fastens to the open end of the reservoir tube (6) with the shaft (3) and the sample collection (4) assembly fitting easily inside the reservoir tube.

Embryos not oriented as desired are directed into a reservoir tube by the flow direction means, after which the flow is directed from the reservoir tube to the outlet thereby having reoriented the embryo.

The device (20) has a thermal buffer tube (44) which extends through the thermally insulating (22) and the other thermal components (14-18).

To dispense material from the tubular member, a first opening (27) is provided on the tubular container, a second opening (40) is provided on a top wall (32) of the closure member, and a third opening (52) is formed on an inner disk member (50).
