METHOD OF PREPARING GEL CONTAINING CAPILLARIES

摘要

Described is a method of preparing polyacrylamide gel containing capillary tube wherein acrylamide is polymerized from a liquid to a gel within the tube, the improvement comprising the steps of: a) after the polymerization, annealing the gel inside the tube by cycling the gel/tube at least once in a temperature range from 20 DEG C to a temperature not to exceed about 75 DEG C and back to ambient; and b) recovering the stress released gel-filled tube. Preferably, the polymerization commences at the middle of the tube and commences toward the extremities of the tube.
