What is a Optical Technician? Optical technicians, also known as ophthalmic laboratory technicians, create eyeglasses and contact lenses as well as lenses for binoculars and other optical devices. They fill prescriptions from ophthalmologists and optometrists, ensuring that the lenses refract light at the proper angle to permit optimal vision.
Needled Silica Insulation. InsulBattÃ¤ 1800 High Temperature needled silica insulation is fabricated from high quality Silica that will not burn and will withstand continuous exposure to temperatures of 1800Â°F / 982Â°C. This material resists most acids and alkalis and is unaffected by most bleaches and solvents. It is highly flexible and conformable.
Type Use the correct type of glass. When heating glassware, make sure to use only glassware made of borosilicate glass (PyrexÂ® brand or KimaxÂ® brand). Common glass can break, explode or shatter very easily when subjected to heat shock. Make sure to use test tubes made of borosilicate glass when heating. Not all test tubes are made of borosilicate glass. Proper Use Each type of glassware has its proper use and should be used only for its intended purpose.
