Embedding mould suitable for anaerobic resins

Abstract

The invention discloses an embedding mould suitable for anaerobic resins. The embedding mould comprises a left mould main body, a right mould main body, a solid octahedron and a top cover, wherein the two sides of the solid octahedron are respectively connected with the left mould main body and the right mould main body; the left mould main body, the right mould main body and the solid octahedron are all connected with the top cover; the left mould main body comprises an eight-prism groove, a left raised line, a right raised line, a left threaded hole, a right threaded hole, a left gap and a right gap; the left raised line and the right raised line are both connected with the eight-prism groove; the left raised line is positioned on the left side of the right raised line; the left threaded hole is formed in the left raised line; and the right threaded hole is formed in the right raised line. According to the embedding mould, the placement of samples is easy, samples cannot be extruded and deformed in an embedding process and can be detached; polymerized resin samples are convenient and easy to take, an airtight system is formed, and the mould is suitable for polymerizing anaerobic resins; the limitation to the size is avoided, and the embedding mould can be adapted to biological tissue sample embedding of different sizes, is easy to operate, and is suitable for being popularized and used in a general laboratory.

Description

technical field [0001] The invention relates to an embedding mold, in particular to an embedding mold suitable for anaerobic resin. Background technique [0002] In order to obtain high-resolution fine structure information of biological tissues, researchers embed biological tissues in resin with high hardness, and prepare ultra-thin tissue sections for electron microscope and optical microscope imaging observation. A class of anaerobic resins (such as GMA, HM20, etc.) exhibit excellent characteristics for embedding tissues. However, the polymerization conditions of this type of resin are very harsh, and strict oxygen barrier is required during the polymerization process, otherwise the um slice requirement cannot be achieved or even polymerization cannot be achieved. Therefore, we put forward higher requirements for the sealing of the resin embedding environment. [0003] In addition, due to the large differences in the size of biological tissue samples of different specie...

Problems solved by technology

[0005] ① Embedding molds with poor sealing performance or silicone molds with openings are only suitable for embedding with non-anaerobic resins

With the continuous expansion of research needs, our samples will gradually transition from smaller-sized biological tissues (such as mouse brains) to larger-sized biological tissues (such as monkey brains), and gelatin for embedding mouse brains Capsules can no longer meet our needs

[0007] In addition, all kinds of packaging boxes with better airtightness on the market have the disadvantages of unsuitable shapes and sizes, and are not easy to dismantle.

[0008] In summary, the current resin embedding molds mainly have the problems of poor sealing or too small volume, while other alternative products have the disadvantages of unsuitable shape and size, and are not easy to disassemble.
