    In my previous lab we used to verify glassware volume using gravimetric method (analytical balance).

    For pipettes, we dispense type 0 water equilibriated at 25.0 C into a tared container and record the weight

    For vol flasks, we take tared weight after thorough air-drying and measure the filled weight with 25C water.

    For burettes, we dispense specific volumes of water in a tared container.

    would love to hear how other laboratories did their verification
