AMI DensiPyc 1000 Precision True Density Analyzer
Advanced, Automated Gas Pycnometer with Industry-First In-Situ Balance
The AMI DensiPyc 1000 Series delivers accurate, highly repeatable true density measurements by combining advanced gas displacement pycnometry with intelligent automation. Fully compliant with ISO 12154, it minimizes operator dependence and optimizes laboratory workflow through customizable modular configurations.
Key Advantages & Features
- Automated Sample Chamber Sealing: Applies constant mechanical sealing force for every test run, eliminating manual tightening errors and user variability.
- Optional In-Situ Automatic Weighing (B Models): Integrated microbalance allows samples to be weighed directly inside the instrument—eliminating external balance transfers and improving data traceability.
- Intelligent Reference Volume Management: Software automatically selects the optimal internal reference volume based on the installed sample cup to minimize dead volume effects.
- Peltier Temperature Control (TC Models): Active thermal regulation from 4℃ to 60℃ (±0.01℃ stability) for temperature-sensitive materials.
- Integrated Vacuum Degassing (V Models): Built-in vacuum conditioning down to 10 kPa removes residual moisture and trapped gases prior to testing.
- Powder Guard Mode & Pulsed Injection: Specialized gas delivery modes safely handle fine powders without elutriation or sample loss.
Flexible Model Configurations
- DensiPyc 1000: Standard configuration for ambient QC and routine true density testing.
- DensiPyc 1000 TC: Equipped with Peltier active temperature control.
- DensiPyc 1000 B: Equipped with an integrated automated balance.
- DensiPyc 1000 V: Equipped with integrated vacuum degassing.
- DensiPyc 1000-TCBV: Flagship configuration combining Temperature Control, In-Situ Balance, and Vacuum Degassing.
Frequently Asked Questions (FAQ)
- True Density (Skeletal Density): The mass of a solid material divided by its true volume, excluding open/closed internal pores and voids between particles. AMI gas pycnometers measure true density using Helium or Nitrogen gas displacement.
- Bulk Density: The mass of a powder divided by the total volume it occupies, including internal pores and spaces between particles.
AMI instruments comply with major global standard testing guidelines, including:
- ISO 12154: Gas displacement method for density determination
- USP <699>: Bulk density and tapped density of powders / true density
- ASTM Standards: ASTM D4892, B923 (Metal powders), C604, C830 (Refractories)
- DIN 66137: Determination of solid density by gas pycnometry
- AMI Densi 100: Best suited for fast (3-minute), routine quality control testing of powders, granules, and solid blocks at an economical footprint.
- AMI DensiPyc 1000 Series: Best suited for advanced R&D or rigorous QC requiring automated mechanical sealing, in-situ sample weighing, active Peltier temperature control (4℃ – 60℃), or vacuum degassing for moisture-sensitive samples.
