Tool for extracting electrophoretic sample

摘要

A gel extraction device (10) comprises a hollow cutting member (12) having cutting edge (14) at one end and a squeeze bulb (16) at the other end. In a further embodiment, the air passage between the cutting edge and the bulb has a constriction zone (20) to prevent any extracted gel from being drawn too deeply into the extractor, in another embodiment, a blow-hole in the hollow cutting member or in the squeeze bulb provides for the passage of air displaced by gel through the extractor. The blow-hole may be covered to secure the gel in the receptacle for transfer from the matrix to a sample container.
