Preparation before the operation of the ultra-clean workbench Preparation for the training Before the start of the experiment, the experimental plan and operating procedures should be prepared. The calculation of the data must be done in advance. According to the requirements of the experiment, prepare all kinds of required equipment and articles, put them into the operation place (cultivation room, clean bench) after the inventory is correct, and then start disinfection. This can avoid increasing the chance of contamination after the start of the experiment because the items are not fully taken back and forth. Operation field disinfection sterile culture room should be used to mop the ground once every day with 0.2% Xinjieer (special for mop), disinfection with ultraviolet radiation for 30-50min, and ultra-clean work table top should use 75% before each experiment.
Preparation before the operation of the clean bench
Preparation before training
Develop experimental plans and procedures before starting the experiment. The calculation of the data must be done in advance. According to the requirements of the experiment, prepare all kinds of required equipment and articles, put them into the operation place (cultivation room, clean bench) after the inventory is correct, and then start disinfection. This can avoid increasing the chance of contamination after the start of the experiment because the items are not fully taken back and forth.
Operation field disinfection
The sterile culture room should be mopped once a day with 0.2% Xinjieer (use of mop), disinfected by ultraviolet radiation for 30-50 minutes, and the clean bench top should be scrubbed with 75% alcohol before each experiment. Then UV disinfection for 30min. When disinfecting KLC ultra-clean work surface, do not irradiate the culture cells and culture liquid at the same time. Do not place too much or overlap on the work surface when disinfecting, otherwise it will block the radiation and reduce the disinfection effect. Operating utensils such as pipettes, waste liquid tanks, dirt boxes, test tube racks, etc. are scrubbed with 75% alcohol and placed in the table while UV disinfection.
Washing hands and dress
In principle, it is the same as surgery. Usually only observe and do not do the cultivation operation, you can wear the cleaning clothes under the ultraviolet irradiation for 30 minutes in the cell culture room. When working with the clean bench, the entire forearm should be inserted into the box, and the long-sleeved clean overalls should be used, and the hands should be disinfected with 75% alcohol before starting the operation. If the hand touches potentially contaminated items and enters the culture room during the experiment, wash the hands again with disinfectant. To enter the primary culture room, you need to wash your hands thoroughly and wear a mask and a sterile coat.

Zoology Slides Series. Contain the from Protozoa to mammal etc mammals experimental lesson used slice (slides) specimens.There are four basic types of animal tissues: muscle tissue, nervous tissue, connective tissue, and epithelial tissue. All animal tissues are considered to be subtypes of these four principal tissue types. Common staining methods: HE, alcohol magenta.
