yield a residue of less than 0.045% of their initial weight. They are hydrophilic with a non-cytotoxic wetting agent extractable
level of less than 4% of their weight.
are two membranes that offer exceptionally low tare weights, are non-hygroscopic, and exhibit extremely low absorption and
adsorption losses. Since these membranes are non-hygroscopic, they are particularly well suited for gravimetric analysis. They
do not require drying when used directly out of the package. If they are wet, they can be dried rapidly and will not pick up moisture
from the air during weighing.
