Abstract

Apparatus for cooling a biological or medical specimen comprises a cooling bath, an injection device for injecting a specimen into cooling liquid in the bath at a velocity of between 5 and 15 m/sec, and a sleeve. The sleeve is movable between a lower position in the bath and an upper position for limiting the effects of splashing as a specimen enters the bath. The injection device comprises a closure plate for co-operating with the sleeve to further limit the effects of splashing. The sleeve is operatively associated with the injection device in a manner such that movement of a specimen carrier of the device towards the bath to immerse a specimen is initiated when the sleeve is moved from the lower position to the upper position.
