materials

filter device

copolymer styrene/butadiene

membrane

millipore ultracell low-binding regenerated cellulose

collection tube

polypropylene

the ultrafiltration membranes in amicon ultra-2 ml devices contain trace amounts of the following:

amicon ultra 3k, 10k, 30k, 50k, 100k devices: glycerine

if these materials interfere with analysis, pre-rinse the device with buffer or milli-q water. if interference continues, rinse with 0.1 n naoh followed by a second spin of buffer or milli-q water.
