Nuclepore track-etched polycarbonate membranes are manufactured from high-quality polycarbonate film and have sharply defined pore sizes, high flow rates, and excellent chemical and thermal resistance.
The membranes have a smooth flat surface and exhibit very low levels of extractables.
Grade 44: 3 μm*
Thin version of Grade 42 retaining very fine particles but with lower ash weight per sample and almost twice the flow rate of Grade 42.
Whatman gridded filters have clearly defined grid lines spaced at 3.1 or 5 mm intervals.
The special ink used is nontoxic and completely
free from bacterial growth inhibitors.
Whatman black mixed cellulose esters are available plain for automatic colony
counting applications, as well as gridded to assist in manual counting procedures.
Black membranes provide contrast between residue or cell colors and the filter
without having to counter-stain the membrane.
Grade 42: 2.5 μm*(Ashless Grades)
Used for critical gravimetric analysis with the finest particle retention of all
Whatman cellulose filter papers.
Typical analytical precipitates include barium sulfate, metastannic acid, and finely precipitated calcium carbonate.
