These thin-bore capillary tubes are ideal for applying TLC samples when high accuracy and precision are not required. Sample volume is estimated visually. Full volume is approximately 9 uL (75 mm length).
…capillary tubes cut to predetermined lengths so that fill volumes are constant and precise. Microcaps are inexpensive and disposable. Using a Microcap is simple. Capillary action draws the fluid into the tube and a squeeze of the bulb will dispense it. For spotting applications such as TLC, a…
