Micro Capillary Tubes

Micro-capillary tubes, ideal for spotting TLC plates or chromatography paper due to the small volume of liquid contained within each narrow bore tube. The liquid to be spotted is drawn up into the glass tube by capillary action and will be drawn back out by touching the end onto a TLC plate or chromatography paper. Supplied in packs of 100 glass tubes, each 75 microlitre volume.
