Embodiment 1

[0023] The mass ratio is composed of 1%% acrylamide compound, 30% Tris-HCl, 0.1% N,N-methylenebisacrylamide, 20% sodium lauryl sulfate and 38.5% water The solution with a pH of 5.0 was prepared and packed into a pre-prepared sample bottle, the carcass of the small goldfish was put into it, and 0.5% ammonium persulfate was added and waited for 3 minutes, and the solution solidified into a gel. Get small goldfish gel specimens.

[0024] The specimens were observed at 1 month, 3 months, 6 months, 12 months, and 24 months after the preparation of the specimens, and it was found that the state, color, and shape of the small goldfish had no obvious changes.

[0025] In the 24th month after the preparation of the specimen, the small goldfish was taken out for observation after being rinsed. It was found that the state, color and shape of the small goldfish did not change. Afterwards, it was placed in a normal indoor environment. After 3 days of observation, it was found that the smal...

Embodiment 2

[0027] The pH composed of 10% acrylamide compound, 15% Tris-HCl, 0.5% N,N-methylenebisacrylamide, 5% sodium lauryl sulfate and 78.5% water Prepare the solution of 3.5 and put it into the pre-prepared sample bottle, put the small conch carcass into it, add 1.0% ammonium persulfate and wait for 3-5 minutes, the solution solidifies into a gel. After 2 years, the small conch state, No change in luster or shape.

[0028] The small conch specimens were observed at 1 month, 3 months, 6 months, 12 months, and 24 months after the specimen preparation, and it was found that the state, color, and shape of the small conch did not change. In the 24th month after the preparation of the specimen, the small conch was taken out and rinsed, and then observed. It was found that the state, color, and shape of the small conch had not changed. Afterwards, it was placed in a normal indoor environment. After 3 days of observation, it was found that the small conch began to rot spoiled.

Abstract

The invention relates to a novel animal specimen preservation gel as well as a preparation method and use thereof and belongs to the field of environment-friendly novel materials. The gel is prepared from the raw materials in percentage by mass: 1-10% of acrylamide compound, 15-30% of Tris-HCl, 0.1-0.5% of N,N-methylene-bis-acrylamide, 5-20% of sodium lauryl sulfate, 0.5-1.0% of ammonium persulfate and 38.5-78.5% of solution which is prepared from water and has the pH of 3.5-5.0. The pH is 3.5-5.0, so that animals and plants are effectively inhibited from breeding bacteria and molds; the animal specimen preservation gel disclosed by the invention has good effects on preservation, fixation, sterilization and corrosion prevention; the preservation gel is simple and convenient to prepare, the raw materials are all low-toxicity environment-friendly chemicals, and the injury / harm to the human / environment is little, so that the gel is a very good product for producing an animal / plant specimen and is convenient to transport.

Description

technical field [0001] The invention relates to a gel for preserving animal specimens, which belongs to the field of new environmental protection materials. technical background [0002] As we all know, keeping specimens in transparent liquids to keep specimens as original as possible is beneficial to scientific research, teaching and people’s viewing. The liquids currently used are mainly formaldehyde solutions and volatile alcohol solutions. However, formaldehyde It has a strong pungent smell. During the process of production and use, it not only pollutes the environment, but more importantly, endangers human health. In addition, it is inconvenient to transport. [0003] Ethanol can be used as disinfectant and bactericide in medicine, be inspired by this traditional practice, develop the animal specimen preservation liquid with ethanol as active ingredient in recent years, disclose a kind of biological specimen color-preserving preservative as Chinese patent CN88105221A ,...
