Pycnometers for Accurate Density Measurement
Our curated collection of pycnometers is designed for laboratories requiring precise and repeatable density measurements across a range of materials:
- Liquid and solid density testing: Pycnometers are widely used to determine density by measuring mass and volume with high accuracy, making them suitable for chemical, pharmaceutical, and materials testing.
- Glass laboratory construction: Manufactured from high-quality borosilicate glass, these instruments provide chemical resistance and dimensional stability during repeated laboratory use.
- Calibrated and non-calibrated options: Laboratories can select calibrated density bottles for higher precision work or non-calibrated variants for general testing and routine workflows.
How to Choose the Right Pycnometers
Selecting the correct pycnometer requires evaluating your measurement requirements, sample type, and level of accuracy:
- Volume selection: Choose the appropriate capacity, such as 5 mL, 25 mL, or 100 mL, based on sample availability and measurement precision requirements.
- Calibration needs: For regulated or high-accuracy environments, calibrated pycnometers provide traceable measurement confidence.
- Application type: Consider whether your laboratory is measuring liquids, powders, or solid samples, as this may influence the preferred design and workflow.

Frequently Asked Questions
What is a pycnometer used for?
A pycnometer is used to determine the density of liquids or solids by measuring mass relative to a known volume. It is commonly used in laboratories for analytical and quality control applications.
What is the difference between a calibrated and non-calibrated pycnometer?
Calibrated pycnometers provide verified volume accuracy and are suitable for precise measurements, while non-calibrated versions are typically used for general laboratory work where exact traceability is not required.
Can pycnometers be used for both liquids and solids?
Yes. Pycnometers can be used for both liquids and certain solid materials, depending on the measurement method and laboratory procedure being applied.
