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 are the parts of pycnometer?
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.
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?

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.
What has the author A M Geddis written?
A. M. Geddis has written: 'Rapid estimate of solid volume in large tuff cores using a gas pycnometer' -- subject(s): Sampling, Soils, Volcanic ash, tuff, Pycnometer

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.
What does a pycnometer measure?
A major application of a micropycnometer is that it allows one to measure the density of a solution when one only has a small volume available. For example, I would like to know the density of an H2018 sample. This stuff costs several hundred dollars per mL. My desitometer requires a minimum of 1.2mL. If I had a micropycnomter, I could get away with only needing a fraction of that amount
