Problems solved by technology

Labels are essential in the preservation of biological specimens, which can be divided into two types, one is the outer label, which is pasted on the outer surface of the transparent container with a self-adhesive label, which is easy to wear and stain; the other is the inner label , the label is pasted in the transparent container, which overcomes the shortcomings of the outer label that is easy to wear and stain
In the prior art, traditional glue is mainly used for pasting, and the label will fall off after a period of time, and the handwriting will become blurred, so it is not conducive to long-term storage

Embodiment 1

[0019] The internal label fixative for biological specimens preserved in formalin, the components and weight percentages are as follows:

[0020] Gelatin 2%;

[0021] Allicin 5%;

[0022] Glacial acetic acid 5%;

[0023] Water 88%.

[0024] Preparation method: weigh the gelatin according to the formula, put it into the water of the formula, and then keep it in an electric heating constant temperature water temperature box at 80°C for 20 minutes. Label fixative.

[0025] How to use: Design the name of the specimen to a suitable size, print it on ordinary A4 paper, and then cut it to the required size as a label; immerse the label in the prepared inner label fixative for 1 to 2 minutes, then use flat tweezers to pick it up, Stick it on the inner wall of the transparent container, and make the surface of the specimen name as the sticking surface. After leveling and removing the air bubbles, evenly smear the back of the label with formalin with a formaldehyde concentration of ...

Abstract

The invention discloses an interior label stationary liquid for a biological specimen preserved through formalin, a preparation method and application thereof. The interior label stationary liquid comprises the components in percentage by weight as follows: 1%-60% of gelatin, 0.1%-10% of allicin, 0.1%-10% of glacial acetic acid, and the balance of water. The interior label stationary liquid is used for fixing an interior label of the biological specimen preserved through the formalin, characters are clear as before after long-term preservation, and the label is not prone to falling off, so that the interior label stationary liquid has a wide application prospect.

Description

technical field [0001] The invention relates to an internal label fixative solution for preserving biological specimens in formalin, and also relates to a preparation method and application of the internal label fixative solution. Background technique [0002] Formalin immersion preservation of biological specimens is the most commonly used method of preservation, and the prepared specimens are generally placed in transparent containers. Labels are essential in the preservation of biological specimens, which can be divided into two types, one is the outer label, which is pasted on the outer surface of the transparent container with a self-adhesive label, which is easy to wear and stain; the other is the inner label , the label is pasted in the transparent container, which overcomes the shortcomings of the outer label that is easy to wear and stain. In the prior art, traditional glue is mainly used for pasting, and the label will fall off after a period of time, and the hand...
