Discussion on the Installation of Syringe Filter and Filter Membrane
Now let’s discuss two issues related to the installation of the syringe filter and the filter membrane.
1. How many minutes does the membrane wet with deionized water before filming?
It is not important to wet the filter membrane with deionized water for a few minutes before filling the membrane, as long as it is wetted.
2. After installation, use a syringe to check for leaks and then sterilize. However, it is checked again with a syringe before filtration, and it is found that the syringe that does not leak before sterilization is leaked after being sterilized. Can the syringe filter still be used?
Unusable. It is often the case that the smaller the syringe filter, the more likely it is to occur. When preparing or sterilizing, loosen the filter and tighten it. The small filter (25mm/33mm diameter) is 75 psi when used or tested, which is equivalent to 4.5kg. Do not use too much force. Otherwise, the filter membrane will be deformed and lose its effect during use. Use even force when testing.
