Mixed Cellulose Esters (MCE) Membrane Filters, Plain: In gravimetric analysis using ashing techniques, (MCE) Nitrocellulose filters
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.

Polycarbonate Track-Etch Membranes (PCTE) - 25mm: Polycarbonate Track-Etch or our Polyester Track-Etch (PETE) membranes
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.

Analytical Filter Funnels: Funnels are available complete with low hold-up polypropylene support pads, gravimetric analysis is one
of the ideal applications for this product. Each package of 12 units comes with an extender that adapts the unit for side-arm flask
filtrations. Optional No. 8 rubber stoppers may be ordered for filtering with flask.
