The AMI DensiPyc Series delivers precise, repeatable true density measurement by combining advanced gas pycnometry with intelligent automation and flexible system configurations. Designed for both research and production environments, DensiPyc minimizes operator dependence while ensuring reliable, traceable results.
By integrating key measurement and control functions directly into the instrument, DensiPyc improves workflow efficiency, reduces potential error sources, and increases confidence in every reported value. All models comply with ISO 12154 for gas displacement density measurement using helium or nitrogen.
The AMI DensiPyc Series stands apart from traditional gas pycnometers by combining smart automation, flexible configurations, and precision features that enhance both productivity and data quality.
• Automated Sample Chamber Sealing
The DensiPyc uses an automated mechanical sealing system that applies consistent sealing force and positioning for every measurement. This eliminates variability introduced by manual tightening and improves repeatability across users and test runs.
• Intelligent Reference Volume Management
Multiple internal reference volumes are integrated into the system. During analysis, the software automatically selects the optimal reference configuration based on the installed sample cell, minimizing dead volume effects and improving volumetric accuracy across different sample sizes.
• Optional In-Situ Automatic Weighing (B Models)
Select models feature an integrated microbalance that allows samples to be weighed directly inside the instrument. This eliminates external weighing steps, reduces handling errors, improves traceability, and streamlines the workflow from loading through final reporting.
• Temperature-Control Options (TC models)
For samples that are temperature-sensitive, the TC (Temperature Control) models offer precise thermal regulation from 4°C to 60°C via an integrated Peltier module. This ensures consistent conditions and repeatable results, even for challenging materials.
• Vacuum Degassing Options (V models)
For materials that require pre-treatment prior to analysis, the V (Vacuum Degassing) models provide integrated vacuum conditioning to remove residual gases or moisture from the sample. The system supports vacuum levels down to 10 kPa, improving sample consistency and measurement repeatability, while maintaining a streamlined, single-instrument workflow.
The DensiPyc Series is designed not only for speed and convenience, but for laboratory-grade precision and data consistency. Its software environment combines guided workflows with automated data handling to minimize operator dependence while maintaining rigorous measurement control. This approach ensures reliable results in both routine quality control and advanced material characterization applications.
Fast Test Mode
The DensiPyc software includes predefined test routines that allow standardized measurements to be initiated with minimal parameter setup. This simplifies operation for routine quality control while maintaining consistent test conditions across operators and laboratories, making the system well suited for high-throughput environments.
Intuitive Data Processing & Reporting
Automated data processing and one-click report generation streamline result evaluation and documentation. Measurement data can be exported in common file formats, while built-in tools enable easy comparison of historical and batch-to-batch results to support process monitoring and trend analysis.
