Material | Glass |
Specification(mm) | 280*280-300*500 |
Packing | 10 pieces/box, 60 pieces/carton |
Product use:
It is suitable for scientific research units in medical and health, medical schools, and epidemic prevention stations to study bacterial morphology. It is suitable for making slides or coverslips coated with bacterial specimens such as sputum, mucus secretions, thick juices, or animal and plant specimens. Staining is a staining device used to store staining liquid and soak slides or coverslips.
Instructions:
Insert the slides coated with bacterial specimens such as sputum, mucus, secretions, etc. into the compartment of the dyeing vat. Gram dyeing is commonly used. First, use basic dye crystal violet or gentian violet dye to dye the specimen. After coloring, add iodine solution to fix the dye on the dyed object, use alcohol to decolorize part of the positive bacteria, and then transfer it to the dyeing vat of fuchsin dye for the second dyeing. Bacteria that are dyed purple are called Gram-negative bacteria, and bacteria that can be decolored by alcohol and are dyed red are called Gram-positive bacteria. Finally, rinse away the excess dye on the slide with water, and observe the bacterial status, bacterial flagella, and spore buds through a microscope (because unstained flagella and spore buds of bacteria are transparent, it is difficult to observe their full picture). Staining methods can be used to identify the type of bacteria.
