• The original, disposable Drummond Microcap
  • The most accurate (±1%)1
  • The most dependable
  • The easiest to use micropipet available anywhere!
  • Drummond Microcaps are a fast, safe, clean, and accurate way to transfer liquids in micro quantities. They are precision-bore glass 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 unique spotting holder is available which will allow the liquid to be dispensed simply by touching the tube to the spotting surface. 1Volume 45, No. 8, Analytical Chemistry, Carl F.
