Borofloat 33 (BF33) is often chosen by researchers for its durability and resistance to thermal shock. BF33 including silica has very low coefficients of thermal expansion. BF33 has a much higher melting point, over 1500 degrees fahrenheit, than other glass. BF33's is often used in research lab equipment, as well as optical and lighting applications.
Borfloat 33 will break, but it will not shatter. Thus it's easier to handle when there is an accident.
Borfloat 33 hypoallergenic and doesn't contain any lead.
When you need the following properties BF33 is the right choice!
We have a large selection of Borofloat 33 glass wafers in all sizes. We have borofloat as thin as 100 microns. Borofloat 33 is the sanme as Pyrex 7740 and have the same anondic bonding properties. Diameters range from smalled diced pieces up to 12 inches.
BOROFLOAT® 33 is a high quality boro-silicate glass with outstanding properties for a wide-range of applications.
This unique special float glass is manu-factured by SCHOTT JENAer GLAS using the Microfloat process and the latest technology. This technology also results in a homogeneous material that has an excellent mirror-like surface, a high degree of flatness and an outstanding optical quality.
BOROFLOAT® 33 is a clear and transpar-ent colourless glass. Its excellent trans-mission and its very weak fluorescence intensities over the entire light spectrum make BOROFLOAT® 33 ideal for a wide range of applications in optics, optoelec-tronics, photonics and analytical equip-ment.
Its low thermal expansion, its high thermal shock resistance and its ability to withstand temperatures up to 450°C for long periods make BOROFLOAT® 33 a good choice for applications which call for good temperature stability (e.g. internal panels in pyrolytic self-cleaning ovens and over plates for high-power floodlights).
BOROFLOAT® 33 is highly resistant to attack by water, strong acids, alkalis as well as organic substances. Therefore it is particularly suitable for applications in the chemical industry such as sight glas-ses for reaction vessels and fittings.
Another interesting field of application is in medical and analytical technology. Measurements are hardly influenced by the glass receptacle because the expo-sure to water and acids results only in the leaching out of small amounts of ions from the glass.
BOROFLOAT® 33 has a lower density than soda lime float glass. It makes it possible to construct lightweight lamina-ted glass systems (e.g. bulletproof glass).
BOROFLOAT® 33 has proven itself in many traditional applications and, today, there is an increasing area of usage in new and technically sophisticated special glass applications such as biotechnology, microelectronics and photovoltaics.
