Straight glass borosilicate tubing that can be heated and shaped. Outer diameter 12mm. Wall thickness 2mm. Overall length 725mm. Ends are snap cut so can be sharp. Fire-polishing is available at an additional cost.
Our borosilicate glass tubing has snap cut ends, meaning the edges can be very sharp and uneven. The glass tubing is basically scored with a file and then 'snapped' between the thumb and forefinger leaving an edge that is rough.
Fire polishing is when the ends of the glass tubing are heated to create a smooth rounded finish that is not sharp at all.
