Rasayan Pyknometer with Thermometer

Rasayan Pyknometer with a thermometer is a laboratory instrument used to measure the density of liquids. The Pyknometer is a small, narrow-necked flask with a precisely known volume. The process involves weighing the empty Pyknometer, filling it with the liquid whose density is to be measured, weighing it again with the liquid, and then calculating the density based on the difference in weight and the known volume. The addition of a thermometer to the Pyknometer allows for the measurement of the temperature of the liquid, which is essential because the density of a liquid can vary with temperature. By knowing both the density and the temperature, corrections can be made to standardize the density measurement to a specific temperature, usually 20°C or 25°C depending on the application. This is crucial for accurate and comparable density measurements across different samples and conditions.
