Borosilicate 3.3 Rod

High Borosilicate 3.3 Glass Tube

Borosilicate glass has a wide variety of uses ranging from cookware to lab equipment as well as a component of high quality products such as implantable medical devices and devices used in space exploration

Sizes: OD: 4~315mm Wall Thickness: 0.8~12mm, Length: 1500mm 1800mm.



Red-line glass tube



This borosilicate tubular gage glass is designed with a red line between two white lines. The color contrast makes it easier to read the liquid level. This is achieved by the application of specially developed paints that are bonded to the glass without etching.

- > RESISTANCE TO CHEMICAL
Borosilicate glass is inert to almost all materials except hydroflouric acid (HF) phosphoric acid((H3Po4) and hot strong caustic solutions. Of these Hydroflouric acid has the most serious effect, even when it is present in PPM (parts per million) in solutions. Where as phosphoric acid and caustic solutions cause no problems when cold but at elevatrd temprature corrosion occurs. in case of caustic solutions upto 30% concentration can be handled safely at ambient temperature.

Under actual operating conditions, the effect of turbulence, and traces of other chemicals in the solution may increase of decrease the rate of attack. So it is not possible to give exact figures for corrosion by caustic solutions.

- > THERMAL PROPERTIES
Linear coefficient of thermal expansion
The coefficient of thermal expansion of borosilicate glass over the temperature 0 - 300�°C is 3.3 x 10-6/�°C. This is very low when compared with other glasses and metals. That is why, borosilicate glass is often called low expansion borosilicate glass.
Specific heat
Specific heat between 25C and 300C is average to be 0.233Kcal/Kg, C
Thermal Conductivity
Thermal conductivity is 1.0 Kcal/hr,mC. Over the permissible operating temperature range.
- > RESHAPEING
In the given below are shown characteristic temperature at a determined viscosity, essential for glass reshap.
Lower cooling temperature 1024 poise 515C
Upper cooling temperature 1013 poise 565C
Softening point 107 poise 795C
Reshapeing point 104 poise 120 C
