Pycnometers are glass or metal containers with a precisely determined volume that are used to determine the specific gravity of sand, soil, or powdery material having granules size smaller than 10mm. Pycnometers can also be used in determining the density of the solid phase in a porous solid, but the sample must first be crushed, ground, or powdered to the point that all pores are opened.


Specification

Consists of a 1kg glass jar with brass cone, rubber seal and locking ring.

Spare : It includes a rubber seal provided in a storage box.

Working Principle of Pycnometer

The pycnometer method is based on the determination of the volume of a known mass of soil by the fluid displacement method. The density of solid particles is determined from the mass and volume of the soil.

Application

Pycnometer is mainly used to determine specific gravity of sand, soil, etc. Some of the areas, where it finds application are :

• Soil Analysis
• Battery
• Pharmaceuticals
• Ceramics
