• 500/1500 per pack capillary tubes, 0.3 mm inner diameter, 0.5 mm outer diameter, 100mm length. Made of borosilicate glass. Both ends open.

With a relatively large quantity of 500 or 1500 tubes, at a highly affordable price, one can say goodbye to reusing capillary tubes in TLC spotting (or any other application), other than perhaps using both ends once each. Save the time, effort, washing solvent and risk of contamination, and focus on more important aspects of your research!

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

• As shown in photos, approximate spotting volume as tested for dichloromethane is 20mm x (0.15mm)2 x 3.14 = 1.5µL,

• for acetone is 30mm x (0.15mm)2 x 3.14 = 2µL, and

• for water is 50mm x (0.15mm)2 x 3.14 = 3.5µL. Testing method used is having the tube at a straight up angle and allowing the liquid to keep on climbing until it stops.
