• 500/1000 per pack capillary tubes, 0.5 mm inner diameter, 0.75 mm outer diameter, 100mm length. Made of borosilicate glass

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.

• Upgraded convenient packaging with a 1.5mm diameter hole on cap for easy tube drawing without need to open the cap or keeping it open all the time.
