Straight glass borosilicate tubing that can be heated and shaped. Outer diameter 12mm. Wall thickness 2mm. Overall length 300mm. These lengths are not fire polished (fire polishing is a process that smooths the ends of tubing so they are not sharp and is generally done to a finished product, not glass that is to be heated and worked on).
- Strain temperature: 520°C (approx)
- Annealing temperature: 550ºC (approx)
- Softening temperature: 820ºC (approx)
- Co-efficiency of expansion: 3.3 (3.3士0.1*10-6/K)
