Description

Dyeing frame for gram dyeing

Technical Field

The utility model relates to an experiment teaching aid especially relates to a dyeing frame for gram dyeing.

background

Gram staining is a widely used differential staining method in bacteriology. Gram staining generally comprises four steps of initial staining, mordant staining, decoloration, counterstaining and the like. The main principle is that after the strain to be dyed is subjected to crystal violet initial dyeing and iodine mordant dyeing in sequence, a water-insoluble crystal violet and iodine compound is formed in cell walls.

Gram-positive bacteria are purple after encountering a decolorizing agent; gram-negative bacteria are colorless after encountering a decolorizing agent and are red after being counterdyed by red dyes such as sallow and the like. The gram staining method is very important experimental content for medical and biological students, and the related staining rack is also very important.

Traditional dyeing frame is the plastics material, and a plurality of draw-in grooves can be stood and are inserted many slide glass of fixed good bacterial to with the dyeing frame insert fill with the container of dye liquor in, make the liquid level of dye liquor be higher than the fungus department of scribbling of slide glass, put into the slide glass timing during the dyeing, take out the slide glass after dyeing well, wash with tap washing or distilled water bottle washing, relapse 3 times. The existing dyeing stand has the following defects:

(1) The traditional dyeing stand is of a plastic structure and is not corrosion-resistant, and after the traditional dyeing stand is often used for a school period, the traditional dyeing stand needs to be replaced by a new dyeing stand, so that the cost is high. In addition, the liquid level of the staining solution is higher than the stain-applying position of the slide glass during staining, so the staining solution is relatively wasted.

(2) Because dyeing frame has a plurality of draw-in grooves, after using, need wash a plurality of draw-in grooves, it is longer to the scavenging period of draw-in groove. And the detergent is easy to splash in the washing process, is difficult to wash and causes troubles to users.

(3) Generally, in the teaching process, the dyeing frame is used, each step of dyeing needs to be started simultaneously, and each student needs to complete the corresponding step to carry out the next step, so that students need to wait for each other in the teaching process, and time is wasted.
