● Excellent dimensional stability
● Smooth internal surface
● Smooth external surface
● Good electrical insulation
● Good corrosion resistance
What Is Borosilicate 3.3 Glass Tube?
Borosilicate 3.3 glass tube is one of the most widely recognized types of technical borosilicate glass tubing.
The term “3.3” is commonly associated with an approximate coefficient of linear thermal expansion of 3.3 × 10⁻⁶ K⁻¹.
Because of its low thermal expansion, borosilicate 3.3 glass is particularly suitable for applications involving temperature changes.
Common applications include:
● Laboratory glass tubing
● Industrial sight glasses
