Embodiment Construction

[0012] A specific example of making snakes, fishes, and frogs specimens is as follows:

[0013] a. Sterilization and antisepsis: soak the specimens to be prepared in antiseptic for 5 days;

[0014] b. Cleaning: take the specimen out of the preservative, and wash the preservative with water;

[0015] c. Plasticization: Use polyethylene glycol with a molecular weight of 600 as a plasticizer, and plasticize according to the following steps:

[0016] Low-concentration plasticization: Soak the specimen in 15% polyethylene glycol at 25°C for 2 days;

[0017] Medium-concentration plasticization: Soak the specimen in 50% polyethylene glycol at a temperature of 40°C for 5 days; soak in 75% polyethylene glycol for 5 days;

[0018] High-concentration plasticization: Soak the specimen to be prepared in 100% polyethylene glycol for 7 days at a temperature of 60°C.

Abstract

The invention relates to a method for plasticizing animal and plant specimen, belonging to field of preserving animal and plant body or part of them. The invention is to provide a method for plasticising animal and plant specimen taking carbowax as plasticising agent. The project comprises sterilization, cleaning and plasticising, and during plasticising process, the expected specimen is immersed into carbowax, the concentration of which is increased gradually from 10% to 100%, to make the carbowax replace water in specimen. The invention is applied for preparing animal and plant specimen. The invention is characterized by the nontoxic and non-corrosive specimen and non use of preservative agent.

Description

technical field [0001] The invention belongs to the technical field of preservation of animals, plants or parts thereof. Background technique [0002] The preparation of animal and plant specimens in the prior art adopts stripping, drying or dipping. Dried specimens are prone to mildew, moth and discoloration when preserved. Impregnated specimens are generally preserved with preservatives such as formaldehyde, and the gas produced after formaldehyde volatilizes will pollute the environment. Some technologies, such as the plasticizing preservation method of animal specimens of Guangdong College of Pharmacy, use silicone rubber as a plasticizer to make preserved specimens. Contents of the invention [0003] The technical problem to be solved is to provide a plasticizing preparation method of animal and plant specimens using polyethylene glycol as a plasticizer. [0004] The technical solution to solve the technical problem is as follows, the plasticization preparation met...
