• 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.
