A pycnometer consists of a glass or metal container with a precise volume, a stopper or lid to seal the container, and a thermometer to measure the temperature of the liquid being tested. It may also have a hook or loop for suspending it in a fluid to measure its specific gravity.

Who invented the pycnometer?
1000-1048: Pycnometer: Abū Rayhān al-Bīrūnī
When was the pycnometer invented?
According to the Wikipedia article on the gas pycnometer, the first patent was filed by John E. Shea on 13 Nov 1978 and it was issued on 08 Apr 1980.
Why the shape of pycnometer cap is conical?
Oh, dude, the shape of the pycnometer cap is conical because it allows for easy pouring and minimizes spillage when you're filling it up with liquid. Plus, the conical shape helps to create a tight seal, preventing any leaks or evaporation. So, like, it's basically designed to make your life easier when you're measuring the density of a substance.
How do you use a pycnometer?
Take G-DenPyc 2900 as an example: step 1. weight sample mass; step 2. put sample into sample chamber; step 3. cover sample chamber and switch gas on; step 4. input sample mass into analyzer software and click "start" to operation; step 5. about 5 mins to wait sample results.
Which test should be performed to detect specific gravity of fats and oil?
The specific gravity of fats and oils can be detected using a method called the pycnometer method. In this test, a pycnometer (a specific type of glass bottle with a known volume) is filled with the oil or fat sample, weighed, and then filled with a known reference liquid (often water) to determine the specific gravity.
How do you properly use a pycnometer for measuring the density of a substance?
To properly use a pycnometer for measuring the density of a substance, first clean and dry the pycnometer. Then, weigh the empty pycnometer and record the mass. Fill the pycnometer with the substance, making sure there are no air bubbles. Weigh the filled pycnometer and record the mass. Calculate the density using the formula: density (mass of substance)/(volume of pycnometer).
What are the advantage and disadvantages of pycnometer?

How do you use piknometer?
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.

Why the pycnometer method more accurate than the hydrometer method?
The pycnometer method is more accurate than the hydrometer method because it uses an analytical balance.
When was the pycnometer invented?
According to the Wikipedia article on the gas pycnometer, the first patent was filed by John E. Shea on 13 Nov 1978 and it was issued on 08 Apr 1980.
What is the other name of pycnometer?
The pycnometer is also commonly known as a specific gravity bottle. It is a laboratory device used to measure the density or specific gravity of liquids and solids by determining their mass relative to a known volume.

Why is a conical cap provided to a pycnometer?
A conical cap is provided to a pscnometer to determine the volume of the test sample.
How is a substance's density calculated?
Density is the ratio beween the mass and the volume.Many devices exist in laboratory do determine the density: special analytical balance, pycnometer, helium pycnometer, densimeter (for liquids), electronic densimeter (for liquids) etc.; for perfect geometrical shapes the measurement of dimensions-calculation of volume-weighing are sufficient.
