Product Description & Reviews

This is a device that accurately measures the volume of a glass or metal container. It can measure the volume defined by the density and volume of the liquid by simple weighing. The known volume of the pycnometer can be used to determine the density of the powder, liquid, and particulate. Place in a constant temperature water bath and maintain a constant temperature t. The mass of the pycnometer itself is ω, the total mass is W when filled with pure water, and the total mass when filling the liquid to be measured is W'. Then, the specific gravity dL of the liquid is: dL = (W' - ω) / (W - ω). Temperature range: 0~40°C, temperature index value: 0.5°C. It is suitable for measuring the liquid density in industrial, laboratory, school, agricultural grain and other units, and analyzing the purity, volatile energy or content of the substance. Instructions: 1. Wash the pycnometer and bake it, and record its quality. 2. Put the sample into the bottle to the mouth of the bottle, and transfer it to a constant temperature water bath at 25 °C (the temperature difference does not exceed 1 °C) soak 10-20mn. 3. When the sample reaches this temperature, insert the stopper to allow excess liquid to flow out of the capillary. 4. Wipe the net with a filter paper. Do not touch the pycnometer by hand during wiping to avoid excessive overflow of the solution. 5. After wiping, transfer it to the balance and weigh the mass and then deduct the quality of the bottle, which is the quality of the sample. 6. Make a note of the above temperature conditions and operating procedures, pour the test object to wash, change to distilled water, weigh the mass, and then divide the mass of the test object, that is, the density of the test object.

Features & Highlights

  • 1. This is a device that accurately measures the volume of a glass or metal container. The known volume of the pycnometer can be used to determine the density of the powder, liquid, and particulate. Temperature range: 0~40°C, temperature index value: 0.5°C.
