• 1000 per pack capillary tubes, 0.5mm inner diameter, 0.75mm outer diameter, 100mm length.

• As shown in photos, approximate spotting volume as tested for dichloromethane is 15mm x (0.25mm)2 x 3.14 = 3µL, for acetone is 25mm x (0.25mm)2 x 3.14 = 5µL, and for water is 45mm x (0.25mm)2 x 3.14 = 9µL.

• Testing method used is placing the tube at a straight up angle with only the tip submerged in the liquid and allowing the liquid to keep on climbing until it stops.
