Abstract: The present invention solves a problem of conventional tissue treating apparatuses: liquid chemicals which have been used given times and have become useless in a tissue specimen infiltration treatment and a cleaning liquid which has been used given times and has decreased in cleaning ability are required to be separately discarded/replaces.

Abstract: The present invention provides a paraffin-penetration treatment method for a tissue preparation, which is capable of enabling sufficient penetration of paraffin even into a tissue preparation, into which paraffin can hardly penetrate by a conventional paraffin-penetration treatment method. When the penetration of the paraffin into the tissue preparation is performed by immersing the tissue preparation in molten paraffin after a dehydrating and a degreasing treatments, the method comprises the steps of: immersing the tissue preparation in the molten paraffin so as to allow the paraffin to penetrate into the tissue preparation; cooling the tissue preparation so as to solidify the paraffin having penetrated thereinto; and immersing the tissue preparation in the molten paraffin again so as to melt the paraffin having penetrated thereinto, and the above described solidification treatment and melting treatment are conducted at least once for one tissue preparation.

Abstract: The present invention provides a staining/covering system comprising a staining apparatus and a covering apparatus arranged in close proximity to each other, in which slide glass attached with a specimen sample stained in the staining apparatus can be transferred to the covering apparatus without using an apparatus for conveying the slide glass in the staining apparatus. The staining/covering system comprises the staining apparatus (10) for staining the specimen sample sliced and pasted to the slide glass, and the covering apparatus (12) being arranged in close proximity to the staining apparatus and covering a cover film or a cover glass onto the specimen sample of the slide glass subjected to desired staining in the staining apparatus (10), and the system is characterized in that means for transferring the slide glass having a specimen sample stained in the staining apparatus (10) from the inside of the staining apparatus to the inside of the covering apparatus is provided in the covering apparatus (12).

Abstract: The cover film sticking device is capable of securely sticking cover film pieces on specimen samples on all slide glasses stored in a basket, which starts to stick the cover film pieces formed, by cutting off long cover film unwound from a film roll to a specified length on the specimen samples on the plurality of slide glasses stored in the basket 26 taken out from a load tank 12 filled with a volatile protective solution. The sticking device is characterized by cover film length securing means for unwinding the long cover film from the film roll and extending the same until reaching cutting means so as to secure the cover film of such a length that can form the cover film pieces to be stuck onto the specimen samples on the maximum number of the slide glasses storable in the basket 26 taken out from the load tank 12.
