Apparatus for embedding tissue samples

1. A histology tissue embedding apparatus including a reservoir for an embedding medium and an outlet valve connected to the reservoir through which the embedding medium is dispensable, and including a trigger which control the operation of the outlet valve, the trigger having a rest position in which the outlet valve is closed, wherein the rest position of the trigger in relation to the outlet valve is adjustable, wherein a portion of the trigger is slidably attached to a body of the embedding apparatus and the trigger also includes a lock to retain it so that it is not slidable under normal user operation of the trigger when the lock is locked, but when the lock is unlocked the trigger is slidable so as to adjust its position.

2. An apparatus according to claim 1 , wherein the rest position of the trigger means is adjustable in a direction away from the outlet valve.

3. A histology tissue embedding apparatus including a reservoir for an embedding medium and an outlet valve connected to the reservoir through which the embedding medium is dispensable, and including a trigger which control the operation of the outlet valve, the trigger having a rest position in which the outlet valve is closed, wherein the rest position of the trigger in relation to the outlet valve is adjustable, wherein the outlet valve is a nozzle and the trigger is a paddle, located substantially behind the nozzle, considered from the equipment operator's perspective.

4. An apparatus according to claim 3 , wherein the rest position of the trigger means is adjustable in a direction away from the outlet valve.
