Description

Microorganism staining rack

Technical Field

The utility model relates to a microorganism staining rack, and belongs to the technical field of microorganism experimental equipment.

Background

Gram staining is a widely used differential staining method (belonging to counterstaining) in bacteriology, and can be used for specimen smear or colony smear, and after staining, bacteria are in clear contrast with the environment, and the morphology, arrangement and certain structural characteristics of the bacteria can be clearly observed, so that the differential staining method is used for clinical classification and identification. Staining results bacteria were classified into two major classes, gram positive bacteria (purple) and gram negative bacteria (red). Gram staining solution (rapid method) can shorten the staining time, usually the whole staining process only needs 1 minute, and almost no false negative condition occurs, so that the gram staining solution is the preferred choice of the clinical laboratory for detecting microorganisms. The specific operation method comprises the following steps: 1. adding gentian violet solution for dyeing for 10 seconds, washing with water, and spin-drying; 2. adding iodine solution for dyeing for 10 seconds, washing with water, and spin-drying; 3. adding a decoloring liquid for decoloring for 10-20 seconds, washing with water, and spin-drying; 4. finally, adding a sand yellow solution for counterstaining for 10 seconds, and washing with water; 5. and (5) drying and microscopic examination.

At present, when a gram staining method is clinically adopted, a plurality of groups of sample slides are generally placed on a staining rack at the same time for staining, and as the staining rack is only a placing platform without a fixing device, only one slide sheet can be clamped by forceps for flushing during water washing, the efficiency is low, the staining time is difficult to control, and the sample staining time is long and short, so that the consistency is poor. And if the two slides are close together, dye liquor crossover can be caused, and experimental results are affected.
