Staining Jar Description:
The staining jar is a staining device used in medical and health care, medical schools, epidemic prevention stations, colleges and universities, and scientific research institutions to store staining liquid and soak slides or coverslips when staining bacterial specimens coated with sputum, exudate, secretion, concentrated juice, etc. or slides or coverslips made of animal and plant specimens when studying bacteria and cells.
Instructions:
Insert the glass slide coated with bacterial specimens such as sputum, saliva, and secretions into the compartment of the staining jar. Gram staining is commonly used. First, use alkaline dye crystal violet or gentian violet dye to stain the specimen, then add iodine solution to fix the dye on the stained object, use alcohol to decolorize some positive bacteria, and then transfer to the staining jar of fuchsin dye for a second staining.
All bacteria that are stained purple are called Gram-negative bacteria, and all bacteria that can be decolorized by alcohol and stained red are called Gram-positive bacteria.
Finally, rinse the excess dye on the glass slide with water, and observe the state of bacteria, flagella, and spores of bacteria through a microscope (because the flagella and spores of bacteria that have not been stained are transparent and it is not easy to observe their full appearance).
The staining method can be used to identify the type of bacteria.
Staining Rack Description:
Stainless steel staining rack is a device used to support slides when performing tissue staining operations in pathology laboratories. Made of stainless steel, it is corrosion-resistant, easy to clean, and durable. This staining rack usually has multiple slots and can support multiple slides at the same time, facilitating batch staining operations. Stainless steel staining racks are commonly used equipment in pathology laboratories to support and facilitate tissue staining operations and are important auxiliary tools for pathology research and diagnosis.
Staining Rack Usage:
Pathology stainless steel staining racks are mainly used to support slides for tissue staining operations.
1. Supporting slides: Mainly used to support slides to be stained, ensuring that the slides are firmly placed in the staining solution for tissue staining reactions.
2. Batch staining operations: Since pathology stainless steel staining racks usually have multiple slots, they can support multiple slides at the same time, which is conducive to batch staining operations and improves work efficiency.
3. Staining solution management: During the staining process, the staining rack can be used to hold and support containers of different staining solutions, so that the staining solution is fully in contact with the slide and ensure the uniformity of the staining reaction.
