Process for preparing biological specimen

Abstract

The invention discloses a biological specimen preparation method as follows: a specimen is pressed, shaped and dried; and then a shallow tray is made with a transparent organic plate and three narrow same organic plates; three surfaces of the shallow tray are enclosed and one surface is vacated; the depth of the tray depends on the thickness of the specimen; and then a layer of transparent unsaturated polyester resin with curing agent added is brushed in the tray; the plant or insect specimen is put into the resin in the shallow tray, and a label is put in together; a transparent organic plate is adhered to the shallow tray to form a flat box with an opening arranged on one side end; after the resin is cured, the opening is upward, transparent resin is poured in to embed the specimen in; after the product is cured, the biological specimen is prepared. The product prepared through the method has high transparency, good aging resistant, corrosion resistant, damp proof, mildew proof and moth proof performance. Because of the technical proposal, the invention has the advantages of simple operation, capability of greatly reducing the production cost and leading an embedding method to be convenient for mass production.

Description

Technical field [0001] The invention belongs to the technical field of biological specimens, and in particular relates to a preparation method of biological specimens. Background technique [0002] In the traditional production and preservation of biological specimens, the plant wax leaf specimens are fixed on the table paper after the shaping and drying, covered with white paper, and stored in a dry environment. Insect specimens are placed in cartons after being shaped and dried, and stored in a dry environment with desiccant added. Traditionally produced specimens have strict environmental requirements during preservation. If they are not preserved properly, they are prone to mold and insects, and they are prone to damage during use; There has been a technology for making and preserving plant wax leaf specimens by plasticizing. Although it has improved in terms of production and preservation, the technology of making and preserving plant wax leaf specimens by plasticizing ...

Problems solved by technology

Insect specimens are placed in cartons after being shaped and dried, and stored in a dry environment with desiccant added. Traditionally produced specimens have strict environmental requirements during preservation. If they are not preserved properly, they are prone to mold and insects, and they are prone to damage during use; The technique of making and preserving plant wax leaf specimens through plastic has appeared. Although there has been some improvement in the production and preservation, the technology of making and preserving plant wax leaf specimens through plastic cannot make thicker plant and insect specimens.

The plexiglass embedding method of insect specimens that appeared later solved many problems in the preservation of biological specimens, but the current embedding method has some shortcomings in the production of insect specimens: mainly that such specimens need to be polished after completion, and the larger the surface area of ​​the specimen, the more difficult it is to polish. The greater the difficulty, the higher the cost of the product, limiting the widespread use of this technology
