Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide the application of glucomannan gum in specimen preservation. Glucomannan gum can maintain the complete shape of biological specimens for a long time without any poisonous or corrosive effects on the specimens, avoiding the use of Defects such as hardening, deformation, and fading of the specimen body that are easily caused by solutions such as formaldehyde and ethanol

Embodiment 1

[0024] Clean the goldfish specimens to be preserved, soak them in 5% formaldehyde solution and ethanol solution for 12 hours and fix them, and seal them in glass bottles with 2% glucomannan gel. After three years of preservation, the goldfish specimens The shape and color of the animal did not change, and the limbs were soft, and there was no phenomenon of rigidity or deformation of the limbs.

Embodiment 2

[0026] Clean the maple leaf specimens to be preserved, soak them in 5% formaldehyde solution and ethanol solution for 14 hours and fix them, and seal them in glass bottles with 5% glucomannan gel. After three years of storage, the maple leaf specimens The shape and color of the animal did not change, and the limbs were soft, and there was no phenomenon of rigidity or deformation of the limbs.

Embodiment 3

[0028] Clean the maple leaf specimens to be preserved, soak them in 5% formaldehyde solution and ethanol solution for 14 hours and fix them, and seal them in glass bottles with 3% glucomannan gel. After three years of storage, the maple leaf specimens The shape and color of the animal did not change, and the limbs were soft, and there was no phenomenon of rigidity or deformation of the limbs.

Abstract

The invention relates to the application of glucomannan gum in preservation of specimens, wherein the specimens are animal specimens or plant specimens; the invention also relates to a preservation method of the specimens. The preservation method of the specimens comprises the steps of using a formaldehyde solution and / or an ethanol solution to treat the specimen for 12-24 hours, and then storing the specimen in a sealing way by using glucomannan gum gel; the glucomannan gum is applied to the preservation of the specimens for the first time, and the glucomannan gum is capable of maintaining the complete shapes of the biological specimens for a long time in the preservation process of the specimens and does not has any poison or corrosion effect for the specimens, so that the defects that the organisms of the specimens easily become hard, and are deformed, faded and the like since the formaldehyde solution, the ethanol solution and the like are used can be avoided, and the preserved specimens are convenient to carry and easy to transport; the glucomannan gum is applied to the field of the preservation of the specimens, so that a new idea is provided for the field of the preservation of the specimens; the application of the glucomannan gum in the preservation of the specimens has higher popularization and application values.

Description

technical field [0001] The invention relates to the field of biological specimen preservation, in particular to the application and method of glucomannan gum in specimen preservation. Background technique [0002] Biological specimens are an important material for biology subjects, an important model for school teaching, and an important carrier for scientific communication. The important role played by biological specimens in various fields determines the development direction and broad prospects of the specimen industry in the future. Now, people pay more and more attention to the production and preservation of biological specimens. However, for living things, the methods that people currently know are far from meeting the needs of specimen production and preservation, especially the color preservation of biological specimens is the basic and most important problem that people face. Because the colorfulness of organisms is an important feature of their biodiversity, main...
