All of our borosilicate tubing and rod is measured in millimeters.
Most of the sizes are presented in this format:
a x c for rod, like 3mm x 1500mm (3mm rod)
a = Outer diameter c = length of the tube or rod, usually 4 or 5 feet long 1 inch = 25.4 millimeters
The prices listed below reflect price per pound. Individual tubes and case prices vary due to their different sizes, weights and case quantities. Full cases are approximately 40 - 50 lbs. We will make every effort to deliver the dollar amounts you order, but your final invoice will reflect the weight delivered, rather dollar amount ordered. If you have any questions, please don't hesitate to contact us by phone or email before placing your order!
