HE dyeing device suitable for batch dyeing of various tissues

Abstract

The invention relates to an HE dyeing device suitable for batch dyeing of various tissues. The HE dyeing device comprises a stainless steel multilayer supporting frame, a light-proof liquid storage bottle, a washing liquid storage bottle, a circular porous flow splitting disk, a dropping liquid conduit, a supporting bottom box and a rotatable angle objective table. According to the HE dyeing device provided by the invention, the circular porous flow splitting disk is arranged at a liquid flow conduit, which is similar to a shower head sprinkler type structure, a plurality of drainage tubes areadded, switches are arranged on the drainage tubes, and the number of the switches can be appropriately adjusted according to the experimental needs, and batch dyeing can be simultaneously performedto shorten the operation time; and the rotatable angle objective table is installed in a pulley, the location and angle can be adjusted by a handle, a glass slide neck and liquid waste drainage channel are arranged on the objective table, so that glass slides can be well fixed, and the problem of mutual contamination between the glass slides is solved.

Description

technical field [0001] The invention belongs to the technical field of experimental devices and equipment for research of histopathology and molecular biology, and mainly relates to HE dyeing experimental devices, in particular, it is suitable for performing HE dyeing in batches on various tissues. Background technique [0002] With the widespread application of pathological diagnosis, the requirements for the processing and staining quality of histopathological sections are getting higher and higher. The method of tissue sectioning has gradually been extended to teaching and scientific research experiments, and has developed into a common experimental method. HE staining is used in The most commonly used staining method in the process of making slices, HE staining technology is an experimental technique based on morphology and combined with applied chemical techniques to stain tissues and various cells. It is the most basic and widely used technical method in teaching and s...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a HE dyeing device suitable for batch dyeing of various tissues, capable of dyeing tissue samples in batches, and changing the current situation of manually adding liquid one by one in the existing device. In scientific research experiments, glue-tip droppers or Pasteur pipettes are often used. The amount of liquid added is uneven, and the device cannot be placed at will. The invention can solve the problem of uneven liquid addition. At the same time, the liquid addition device can be placed independently, which is convenient for experiments. operate
