That it meets the tightest tolerances in its ISO standard: the actual volume deviates less from the marked volume than in class B. It is used when the result depends on measuring a volume accurately, as in a titration.
Because it expands very little with heat, withstands sudden temperature changes without breaking and resists most acids and bases. That is why it can be heated, washed hot and used with reagents without being affected.
Rinse it straight after use, wash it with water and laboratory detergent, rinse it with tap water and finally with distilled water. Volumetric glassware is not dried in an oven at high temperature, because it can lose its calibration.
To let dry samples cool or to store them without them picking up moisture from the air. It has a desiccant, such as silica gel, at the bottom and a ground-glass lid that seals airtight.
Balances, thermometers and the rest of the laboratory supplies are in general equipment.
