A graduated cylinder or a volumetric flask would most likely have been used to find the volume of each sample. These lab instruments are designed to accurately measure liquid volumes.

yes,manometer is an instrument . It is used to measure pressure of liquid.
A pycnometer is an instrument used to measure the density or specific gravity of liquids and solids. To use it, first fill the pycnometer with the liquid or solid sample, ensuring there are no air bubbles. Then, weigh the pycnometer with the sample and record the mass. Finally, calculate the density by dividing the mass of the sample by the volume of the pycnometer, which is typically calibrated and known.
liquid
A saccharimeter is an instrument used to measure the sugar content of a liquid.
a viscometer is used to determine viscosity(density) of a liquid.
orsat apparatus
For example to establish a zero point for an instrument or to make a measurement on water considered as a pure sample.
Mrs.Tuft used a hydrometer to determine the specific gravity of a liquid
