Even the best hand cuts in glass capillaries look LOUSY under high magnification (ask us about how we captured these images). This causes gaps in the flow path, which leads to poor chromatographic performance, sample carry over and crushed glass in the fittings and unions.
The Glass Capillary Polishing Station, avaliable exclusivly through ESI Source Solutions, will allow you to make NEAR PERFECT clean and polished ends on your glass capillaries. Check out the images below, with before and after polishing to see for yourself.

As you can see, even a good hand cut (left) compares poorly to the polished capillary (right). The Glass Capillary Polishing Station is a simple, inexpensice, hand operated bench top device which will make your capillary chromatography look as good as it can be.
