Petri dishes were originally designed by Julius Richard Petri (1852-1921), a bacteriologist working under German biologist Robert Koch, in 1887, so they were also known as “Petri dishes”. Petri dishes are fragile and fragile, so they should be carefully cleaned and handled with care. Petri dishes after use had better be cleaned in time and stored in a safe and fixed location to prevent damage and damage.
Generally after immersion, scrub, dip acid, and cleaning four steps.
1. Soak: New or used glassware should first be soaked in water to soften and dissolve the attachment. New glassware should be simply scrubbed with running water before use, and then soaked overnight in 5% hydrochloric acid. Used glassware is often with a lot of protein and oil, dry after not easy to scrub off, so immediately after use should be immersed in clean water for scrub.
2. Scrub: Place the soaked glassware in detergent water and scrub repeatedly with a soft brush. Do not leave dead corners and avoid damaging the surface finish of the vessel. Wash and dry the cleaned glassware and prepare for pickling.
3. Acid leaching: Acid leaching is to soak the above-mentioned vessels in the cleaning solution, also known as the acid solution, and remove the possible residual substances on the surface of the vessels through the strong oxidation of the acid solution. Acid soaking should not be less than 6 hours, usually overnight or longer. Be careful when handling utensils.
4. Rinse: After scrubbing and soaking, the vessels must be fully rinsed with water. Whether the vessels are rinsed clean after soaking directly affects the success or failure of cell culture. Hand wash the vessels after soaking acid, each vessel should be repeatedly “water-emptied” for at least 15 times, and finally soaked and washed with resteamed water for 2-3 times. After drying or drying, the containers should be packaged for use.
