Blaine Air Permeability Apparatus measures the
specific surface area of fine materials in square
centimeters per gram of test sample. A quantity
of air is drawn through a bed of definite porosity.
The pore volume in the bed is a function of the size
of particles, and determines the rate of air flow.
The apparatus is supplied complete with stainless
steel test cell, plunger, perforated disk, calibrated
U-tube manometer, rubber aspirator and bulb, all
mounted on a sturdy wooden panel and base. An
8oz bottle of red spirit manometer fluid, package of
filter paper, and a wood block for holding cell during
filling are included. For calibration, order BS-50,
NIST Portland Cement standard reference material
(20 units). Est. Ship Wt.: 15lb (7kg).
