A precision stainless steel instrument for determining the specific gravity or density of paints and similar products.
A precision stainless steel instrument for determining the specific gravity or density of paints and similar products.
This instrument consists of a container and its corresponding lid with an orifice to evacuate excess liquid under test.
Available in two capacities: 50 or 100 cc, with or without tare for balanced measurements.

Why is density an important parameter in a paint?
Density influences properties such as yield, solids content, application behaviour and product stability. Unexpected variations may indicate changes in the formulation or manufacturing problems.
Why use a pycnometer instead of a conventional balance?
A balance merely measures mass. The pycnometer allows that mass to be related to a precisely known volume, thereby providing an accurate measurement of density.
What are the most commonly used pycnometer capacities in paint laboratories?
The most common capacities are usually 50 ml, 100 ml and 250 ml, although the choice depends on the standard being applied and the volume of sample available.
What is the difference between density and specific gravity in paints and coatings?
Density expresses mass per unit volume (g/cm³ or kg/m³), whilst specific gravity relates the weight of the product to its volume. In industrial applications, both concepts are usually closely related, but they are not exactly equivalent.
