Embodiment 1

[0021] A method for preparing a gel specimen. The materials used include two beakers, 1 g gel, 5 g sugar, 500 ml water, and 10 ml formaldehyde solution. The specific steps are as follows:

[0022] 1) Pour 1g gel, 5g sugar and 500ml water into beaker 1, stir and heat until boiling;

[0023] 2) Pour 200ml of the solution in the beaker 1 described in step 1) into the beaker 2, and place it in an incubator for heat preservation. The remaining 300ml of the solution is left in the beaker 1, and the temperature is slowly reduced to 60°C;

[0024] 3) Put the processed specimens into container 1 at 60°C, fix the position and shape of the specimen with glass wool, and eliminate air bubbles;

[0025] 4) Put the container 1 described in step 3) in the refrigerator until the solution solidifies;

[0026] 5) After the solution described in step 4) is solidified, take out the glass filament used to fix the specimen, slowly pour the solution in the container 2 in the incubator into the container 1 afte...

Embodiment 2

[0032] A method for preparing a gel specimen. The materials used include two beakers, 3g gel, 8g sugar, 600ml water, and 20ml formaldehyde solution. The specific steps are as follows:

[0033] 1) Pour 3g gelatin, 8g sugar and 600ml water into beaker 1, stir and heat until boiling;

[0034] 2) Pour 300ml of the solution in the beaker 1 described in step 1) into the beaker 2 and place it in an incubator for heat preservation. The remaining 300ml solution is left in the beaker 1, and the temperature is slowly reduced to 60°C;

[0035] 3) Put the processed specimens into container 1 at 60°C, fix the position and shape of the specimen with glass wool, and eliminate air bubbles;

[0036] 4) Put the container 1 described in step 3) in the refrigerator until the solution solidifies;

[0037] 5) After the solution described in step 4) is solidified, take out the glass filament used to fix the specimen, slowly pour the solution in the container 2 in the incubator into the container 1 after the so...

Embodiment 3

[0043] The specimens processed in the same steps as in Example 1 and Example 2 were prepared according to the method of the prior art

[0044] 1) Put the complete shape and excellent state of Papua Nitrous jelly in a small but fully stretchable container, and slowly add saturated MgSO 4 Solution to completely anesthetize the jellyfish;

[0045] 2) According to the volume of water in the container, calculate the volume of 37-40% formaldehyde solution on the market to prepare a 5% formaldehyde solution. The volume ratio of formaldehyde: water is 5:95;

[0046] 3) Soak the fully anesthetized jellyfish in 5% (volume percentage) formaldehyde solution for 24h;

[0047] 4) Bundle the jellyfish in step 3) on glass slides with glass wool or cotton thread, and put them in a specimen bottle for storage. The specimen storage solution is 5% (volume percentage) formaldehyde solution.

Abstract

A making method of a gel specimen belongs to the technical field of specimen making. The method comprises a step that a processed specimen is put in a specimen preservation object, the specimen preservation material comprises an upper layer and a lower layer, the upper layer is a liquid formaldehyde layer, and components of the solid gel layer comprises a gel, sugar and water. The depth of the upper-layer formaldehyde liquid is 1-2cm. The components of the solid gel layer concretely comprise 1-3 parts of the gel, 5-8 parts of the sugar and 500-600 parts of water. The method utilizes the transparent and compact characteristic of the gel to make an original specimen, the specimen does not deform or fade, and deformation and fading of the specimen are difficult to overcome. The preservation of the gel specimen in a gel form only needs a small amount of a preservation liquid comprising formaldehyde, alcohol and water, so the consumption of harmful substances is reduced, and harms of volatilization to the environment in the preservation process are reduced. The above used materials are heated as a high temperature, a small amount of formaldehyde is used for sealing, and a container is sealed, so the specimen will not decay.

Description

Technical field [0001] The invention belongs to the technical field of specimen preparation, and specifically relates to a method for preparing a gel specimen. Background technique [0002] Aquatic animals have beautiful morphological characteristics, especially some rare deep-sea creatures, which are colorful and beautiful in shape, and have high ornamental value after being made into specimens. At present, specimens are generally preserved with formaldehyde or alcohol. In order to make the specimens appear beautiful in the preservation solution, glass thread or cotton thread is usually used to bind and fix the specimens. However, alcohol or formaldehyde is used as a preservation solution to preserve the specimens. Later, the specimen loses its original color. If the seal is not good, the formaldehyde volatilizes and causes air pollution. At the same time, it is deformed due to the binding or the binding marks are obvious, and finally the specimen loses its ornamental value. Su...
