<p>A vacuum system for use inside of a cryostat to evacuate and collect debris as it is generated during specimen preparation using a microtome (1), also inside of the cryostat. The system includes a vacuum assembly unit (14) containing a vacuum collection nozzle (8) having a suction duct (7). The cold assembly unit (14) is movably positioned adjacent to the microtome knife (6) so that debris is suctioned away and removed concurrent with or immediately after its production during cryotomy, and is captured in a cold primary filter (18). When required, the collection nozzle (8) and attached assembly unit (14) can be movably positioned out of the way of the microtome knife (6). The system may also include a second bacteriological filter (19) inside or outside of the cryostat to entrap any small quantities of the fine debris which may pass through the primary filter (18) after suctioning.</p> |
