A sharp inner edge of capillary is one of the necessary conditions for successful surface tension measurement of very small liquid samples. Tested production process has two stages. First, the smooth capillary tip surface is achieved with ductile mode fine grinding. Then, grinding continues with gradual decreasing of grinding load. Finally, rests edge chipping defects are minimized with a polishing process. A task to perform quality check of manufactured capillary inner edge was found out to be very complicated. We present a review of our experiences with four experimental techniques for sharp 90° edge sample quality check.
