SorbaTech® Unit Bags

SorbaTech^® Unit Bags conform to the weight and adsorption capacity requirements of MIL-D-3464E and are available in standard sizes from 1/6 to 80 units. These bags are used for a variety of applications including electronics, bulk chemicals, pharmaceuticals and food products.

Military Specification MIL-D-3464E defines, “A desiccant unit is that quantity of desiccant, as received, which will adsorb at equilibrium with air at 25 degrees Celsius at least the following quantities of water vapor:

(a) 3.00 grams at 20 percent relative humidity (R.H.), and
(b) 6.00 grams at 40 percent R.H.”
