The Elutrap system can be used with most horizontal gel electrophoresis chambers. The Elutrap electrophoresis chamber allows for the most efficient flow of current through the device and can be used for up to four samples simultaneously.

Assembly of the Elutrap system is very easy. Gel slices are placed in the middle of the Elutrap device, which is then placed into a horizontal electrophoresis chamber. Molecules migrate from the gel slice into a trap area formed by BT1 and BT2 membranes. The membrane placement is adjustable, allowing final elution trap volumes to be optimized for the particular assay. The Elutrap system can also be used for concentration of dilute solutions.
