MICROPOROUS HYDROPHILIC MEMBRANE |
摘要 |
<p>A hydrophilic microporous membrane comprising a thermoplastic resin, having been subjected to hydrophilizing treatment and having a maximum pore size of 10 to 100 nm, wherein when 3 wt% bovine immunoglobulin having a monomer ratio of 80 wt% or more is filtered at a constant pressure of 0.3 MPa, an average permeation rate (liter/m<2>/h) for 5 minutes from the start of filtration (briefly referred to as globulin permeation rate A) satisfies the following formula (1) and an average permeation rate (liter/m<2>/h) for 5 minutes from the time point of 55 minutes after the start of filtration (briefly referred to as globulin permeation rate B) satisfies the following formula (2): <DF NUM="(1)">Globulin permeation rate A > 0.0015 x maximum pore size (nm)<2.75> </DF> <DF NUM="(2).">Globulin permeation rate B/globulin permeation rate A > 0.2 </DF></p> |
