[0106] Next, the case where various tests are actually performed using the cassette 1 of the present invention and a cassette used in the prior art and the test results are compared is described. The cassette 1 of the present invention is made of a polyester-based resin. The printed surface of the formed cassette body is formed with a thin film layer of polyurethane resin, and in conventional embedding cassettes, the printed surface of the cassette body formed of polyacetal (POM) is formed with a thin film layer of polyurethane resin.

[0107] First, each of the cassettes tested will be briefly described.

[0108] As the cassette 1 of the present invention, as shown in the above-mentioned embodiment, PBT, which is a kind of polyester resin, is selected as the material of the cassette. More specifically, PBT having a trade name of VALOX 310 (manufactured by SABIC Polymerland Japan Co., Ltd.), an average molecular weight of 32,500, and a filler content of 0% was used.

[0126] Next, a description will be given of the results of the same test as in the first embodiment in which the film layer is formed of epoxy resin instead of polyurethane resin as the cartridge body of the present invention.

[0127] As the epoxy-based resin, a material having a trade name of 1300HC870 (manufactured by Seiko Advance Co., Ltd.) and containing carbon black (5% to 10%) as a pigment was used. Then, the epoxy-based resin was formed into a film in the following procedure.

[0128] When this epoxy resin is used, the cartridge body has excellent affinity with the resin compared to other materials, and therefore it is not necessary to corona discharge surface treatment particularly on the printing surface. Then, the epoxy resin dissolved in the solvent is directly screen-printed on the printing surface to form a thin film layer. At this time, the thickness of the thin film layer was 10 μm. Then, after film formation, it was visually confirmed that there were no chi...

Abstract

Disclosed is an embedding cassette which is used as a container to perform paraffin substitution of a biological sample and is used as a support base for an embedding block wherein a biological sample which has undergone paraffin substitution is embedded in an embedding agent. The embedding cassette is equipped with a cassette main body formed from a polyester resin and having a flat printing surface and a concave holding part that holds the aforementioned biological sample, a thin-film layer formed on the aforementioned printing surface by means of a resin which is chemically resistant to formic acid, formalin, ethanol, and xylene, with the resin color differing from that of the color of the aforementioned cassette main body at least in its brightness, and an identification code that is displayed on the aforementioned thin-film layer by cutting using laser irradiation.

Description

technical field [0001] The present invention relates to an embedding cassette which is used as a container for accommodating and substituting a sample taken from a human body or an experimental animal, and is also used as a container for embedding the substituting sample. Fixed table for buried blocks. [0002] This application claims priority based on Patent Application No. 2008-221179 filed in Japan on August 29, 2008, the contents of which are incorporated herein by reference. Background technique [0003] Conventionally, a microtome is generally known as an apparatus for preparing thinly sectioned specimens for physical and chemical experiments or microscopic observation. The thin-section specimen is a structure in which a thin section having a thickness of several micrometers (for example, 3 μm to 5 μm) is fixed on a substrate such as a slide glass. Thin sections are produced by cutting an embedding block of a biological sample embedded with an embedding agent into ex...
