ABSTRACT:
A holder (10) is provided for securing a capillary (30) having a window section (28) including first and second edges (46) (48) to a mount (80). The holder (10) comprises a retaining surface (14) for securing the capillary (30) to the holder (10) and a mounting surface (18) for detachably securing the holder (10) to the mount (80). The retaining surface (14) is attached to the capillary (30) proximate to the opposed first and second edges (46), (48), with a portion of the window section (28) exposed. Since the capillary (30) is secured proximate the opposed first and second edges (46), (48), the fragile capillary window section (28) is protected during manufacturing or installation into an electrophoretic system (32). The retaining surface (14) preferably is sized and shaped to retain a plurality of capillaries (30) to allow for the substantially simultaneous testing of multiple capillaries (30). Optimally, the mounting surface (18) secures the holder (10) to the mount (80) with the capillaries (30) in fluid communication with a support medium supply (106) so that the support medium inside each capillary (30) can be replaced without removing each capillary (30) from the mount (80).
