General description

Extrelut® NT simplifies liquid-liquid extraction in its most effective form by using a chemically inert, wide-pore and highly pure diatomaceous earth based solid phase. Depending on the sample volume three types of columns are available: Extrelut NT1 can take up a maximum of one ml, Extrelut NT3 three ml and Extrelut NT20 up to twenty ml of sample.
