Microporous hydrophilic membrane |
摘要 |
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<SUP>2</SUP>/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<SUP>2</SUP>/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): <?in-line-formulae description="In-line Formulae" end="lead"?>Globulin permeation rate A>0.0015xmaximum pore size (nm)<SUP>2.75 </SUP> (1) <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Globulin permeation rate B/globulin permeation rate A>0.2 (2). <?in-line-formulae description="In-line Formulae" end="tail"?>
