1.The glass bell jar prevents the heat and steam generated during the experiment from causing harm to the experimenter.
2.Great for daily use, halloween, wedding, party decoration as well as lab using and confections for Christmas gifts and scientific themed kids birthday party supplies.
Borosilicate glass 3.3 is one of transparent colorless glass, through wavelength is between 300 nm to 2500 nm, transmissivity is more than 90%. Coefficient of thermal expansion is 3.3. It can acid proof and alkali , the high temperature resistant is about 450°C. If course handling , the high temperature resistant can reach 550°C or so. Apply to lighting fixture , chemical industry , electron, high temperature equipment and so on.
working temperature of 500°C so are excellent for use in high powered light source applications or
an excellent choice for cold and hot mirror substrates.
It is our desire to have the pleasure of serving you.
