Instrumentation Flashcards
Most commonly used for heating and sterilization. Strain point 515c (PYREX)
Borosilicate glass
High alkali resistance and it has weaker thermal resistance than borosilicate
Boron-free glassware
Six times stronger than borosilicate; A special alumina silicate glass that has been strengthened chemically than thermally
Corex (Corning
Utilized for high thermal , drastic heat shock and extreme chemical treatment with acid (except hydrofluoric) dilute alkali can be heated to 900c
Vycor (corning)
Made up of soda lime glass and a mixture of calcium, silicon and sodium oxides.
Poor resistance to high temperature and easy to melt
Flint glass
The 2 under of laboratory vessels
Calibration marks/design
Types of container
It delivers exact amount it holds into a container
TD - To deliver
It holds particular volume but does not dispense exact volume
TC - To contain
To hold on exact volume of liquid
Volumentric flask
To hold different volume (Used in reagent preparation)
Erlenmayer flask & Griffin beakers
To measure volume of liquid
Graduated Cylinder
