Dear Lab Guy, Is it possible to use Flowmi 40 µm strainers to capture the "objects" larger than 40 µm and then extract DNA and RNA by direct lysis in Flowmi and elution?

Dear Lab Guy, I have FlowmI cell strainers cat# 136800040. They say they are designed for P1000 pipettes. I want to use the Rainin 300pipette. Will the fit be tight enough? Am R.
