Glass Types (Sample CC Flash Cards)
5 General Types of Glass
High thermal resistant glass
borosilicate glass with low alkali content
resists heat corrosion and thermal shock
pyrex kimax exax corex
a. Corex
6x stronger than borosilicate glass
alumina-silicate glass
better able to resist clouding due to all alkali or scratching
ideal for higher temperature thermometers graduated cylinders and centrifuge tubes
b. Vycor
application involving high temperature and drastic heat schock and extreme chemical treatment with acids and dilute alkalies
heatable to 900 C and withstand downshock from 900 C to ice water
ideal fro ashing and ignition technique
High Silica Glass
96% silica content comparable to fused quarts in its thermal endurance chemical stability and electrical characteristics
radiation resistant good optical qualities and temperature capabilities
ideal for high precision analytical work and can also be used for optical reflectors and mirrors
Glass with high resistance to alkalies
boron-free glassware for strong alkali solutions and digestion with strong alkalies
less thermal resistant than borosilicate glass
soft glass
Low actinic glass
amber or red-colored to reduce the amount of light passing through the substance within the glassware
highly protective laboratory glassware for handling heat-labile substances in the 300-500nm range (bilirubin carotene vitamin A)
