Approach
1. The newly purchased filtration instrument should be filtered with an acid solution before use, rinsed with distilled water, and dried. For the sterilizing filter, it needs to be autoclaved before use. After use, the washing solution is used for suction filtration, then immersed in the washing liquid for 48 hours, and taken out and rinsed with distilled water for drying and storage. During the drying process, do not open the oven in the middle. Wait until the oven has cooled to room temperature before opening the oven to prevent it from bursting.
2, the filter must be washed after use, so as not to affect the filtration efficiency due to blockage of sediment.
