Product Description

SJ-X100 Medical Face Mask Filter Tester BFE Testing Machine

Face Masks bacterial filtration efficiency BFE tester is to determine the bacterial filtration efficiency (BFE) of medical face mask materials by employing a ratio of the upstream bacterial challenge to downstream residual concentration of the tested medical face mask materials.
