Vacuum Picnometer

Transparent plexiglass made, complete with valve and gauge, it is utilized for a rapid determination of asphalt content, bulk specific gravity of aggregates, the max. theoretic specific gravity of bituminous uncompacted road mixtures and the percent air voids in compacted mixtures.

Dimensions: dia. 300×450 mm

Weight: 10 Kg

Vacuum Pycnometer

The vacuum pycnometer, which is among the asphalt testing devices, is basically an instrument used to measure free weight. It is produced in 2 different ways, with or without a thermometer, which is used to determine the density of liquids, and is used as laboratory material made of special glasses.

It is used to determine the specific gravity of all liquids between 20 and 25 degrees with a thin glass lid closed on a glass balloon.

What Does a Vacuum Pycnometer Do?

A vacuum pycnometer is a device for measuring the mass of liquids. The specific gravity of the liquid was determined with this device, whose measuring devices are occasionally used. Thanks to the vibrators used in the test among the vacuum pycnometer apparatus, air is taken from the process and net measurements are reached.

What does a vacuum pycnometer do? For those wondering, it is possible to say that it is basically a laboratory measuring device and is used for mass measurement of liquids. The air gaps that occur especially in bituminous mixtures are very important and they should be prevented from creating sensitivity on the measurement.

How Does a Vacuum Pycnometer Work?

The vacuum pycnometer, which is used as a test device, is brought into a constant discussion so that there is no moisture in the glass cover, and its mass is measured on the precision scale while it is empty, then the liquid to be measured is added into it and the cover is closed on it and dried with a paper towel so that there is no wetness.

In this state, it is put on the precision balance to calculate its gross mass again and the mass of the liquid is calculated by subtracting the tare mass measured in the empty state from the gross mass.
