Problems solved by technology

The disadvantage is that the dehydration effect is too strong, the specimen shrinkage rate can reach 20%, and the specimens are easy to dry when exposed to the natural environment; it has the effect of dissolving fat, so it is not suitable for preservation of display specimens
As time goes by, the concentration of formaldehyde in the air continues to rise, posing a serious threat to the health of medical workers

Abstract

The invention relates to a specimen preservation composition, its use method and application, and belongs to the technical field of specimen preservation. The specimen preservation composition of the present invention comprises the following components in parts by weight: 10-15 parts of alum, 8-12 parts of potassium nitrate, 5-10 parts of table salt, and 1-2 parts of realgar. After the composition of the present invention is mixed with water, it can obtain reliable anti-corrosion and anti-mildew properties, easy-to-obtain raw materials, low cost, safe and non-toxic use, no bad irritating smell, good preservation effect, no precipitation, no shrinkage of specimens, and natural color specimen preservation solution.

Description

technical field [0001] The present invention relates to the technical field of specimen preservation, in particular to a specimen preservation composition, its use method and application. Background technique [0002] Human anatomy is a highly intuitive morphological science, and teaching activities are inseparable from human specimens. Teachers mainly use human specimens to teach, and students mainly use specimens to learn. [0003] The preservation of human body specimens provides indispensable human body specimens for the teaching and scientific research of human anatomy. The commonly used specimen preservation methods in the prior art are preservation of specimens with liquid preservation and specimen plastination technology. Although the effect of specimen plasticization technology is good, the cost is high. [0004] At present, human specimen preservation solutions are often prepared to preserve human specimens. The commonly used substance is ①alcohol, which not only...
