Merck Extrelut Columns

Merck Extrelut columns are designed as solid phase replacements for traditional liquid-liquid extractions done with a separatory funnel. Merck Extrelut columns contain specially processed wide-pore diatomaceous earth, a chemically inert matrix for use within a pH range of 113. After the sample is pH adjusted or salt is added (as for salting out of the sample) and applied to the Merck Extrelut column, the matrix acts as a holder for the sample. Next, an immiscible organic solvent is passed through the Merck Extrelut column to extract the desired components, which are subsequently analyzed. Strict control of raw material and final product guarantees uniform batch-to-batch quality. Merck Extrelut column is a naturally occurring product and subject to certain fluctuations. Replacement packets 1.15093.0001 are 24g packets for refilling the 20mL Extrelut NT column (1.15096.0001).
