Quick answer: A Pyknometer is a small, precisely-calibrated glass vessel used to determine the density and specific gravity of a liquid sample by measuring its mass at a fixed, known volume. Pyknometer is priced at approximately ₹360 (indicative market benchmark, incl. GST, August 2026).
A pyknometer is a small glass vessel with a fitted capillary stopper that fixes its internal volume precisely. By weighing the pyknometer empty, then filled with a liquid sample, and comparing to the mass of an equal volume of water, students and researchers can calculate the liquid’s density and specific gravity. This method is a standard technique for density determination in college and research chemistry laboratories, valued for its accuracy compared to less precise methods like hydrometers.
