Product catalog summary
Purpose and Application
Pycnometers are utilized to determine the density of coating materials, fluids, and paste products. The density is calculated as the ratio of mass to volume, typically measured at 20°C.
Design and Function
The Pycnometer consists of a container and a lid with an overflow hole, available in anodized aluminum or stainless steel, with volumes of 50 ccm or 100 ccm. Standard models have a tolerance of 0.2%, with an option for 0.1% tolerance and certification.
Test Procedure
The Pycnometer is weighed, filled with the specimen at 20°C, and weighed again. Care is taken to avoid air trapping. A special opening aid is available as an accessory.
Special Note
Stainless steel Pycnometers are recommended for acidic or alkaline substances due to their resistance.
Reference Class
All models come with a Manufacturer’s Certificate in accordance with DIN 55 350-18, detailing volume, product identification, and calibration status. An option for a conformity assessment is available.
Ordering Information
Various models are available in anodized aluminum and stainless steel, with options for conformity assessment and test certificates. Accessories include an opening aid.

Technical Description Model 290-2

Pycnometers are used to establish the density of coating materials and other fluids and paste products. The density r of a substance is the ratio of its mass m to its volume V: Unless otherwise specified, the density of the coating material is given at 20 °C. The density at 20 °C may be specified as r . The density is measured by means of Pycnometers. The Pycnometer container is filled with fluid. The difference in weight between the empty and full Pycnometer and it internal volume enables the density to be calculated. The Pycnometers consist of a container and a lid with an overflow hole.
