Detailed Product Description:
Introduction to the Model 1951 Microprocessor Tap Density Tester:
The Microprocessor Tap Density Tester, Model 1951, is specialized equipment manufactured under the EI (Electronic India) brand, often associated with ESICO International, designed for precision density measurement in laboratory environments. The instrument determines the tapped density of powdered, granulated, or flaked materials through standardized and repeatable procedures. Utilizing advanced microprocessor technology and superior engineering, the Model 1951 delivers enhanced accuracy and reproducibility for critical material characterization.
Key Features and Compliance:
This instrument is an essential tool, particularly for pharmaceutical labs, adhering fully to international regulatory requirements.
• Pharmacopeial Compliance: Complies rigorously with USP (United States Pharmacopeia) and IP (Indian Pharmacopoeia) specifications. The core function is based on determining Tapped Density, defined as the density attained after mechanically tapping a container holding the powder sample.
• Automatic Calculation: Automatically computes essential powder flow parameters, including Tap Density, Initial Density (or Bulk Density), Compressibility Index, and the Hausner Ratio.
• User Interface: Features a 20 x 4 line alphanumeric LCD display with backlighting, coupled with 16 soft touch membrane keys (alphanumeric mobile keypad format) for user-friendly operation and menu navigation.
• Programmable Operation: Offers independent programmable setups for both User mode and USP mode, complete with internal storage capabilities.
• Reliable Data Handling: Automatically stores the last test result and includes a power failure detection facility, ensuring data integrity even after power interruption.
• Connectivity: Provision is included for the attachment of an RS232 printer with a serial interface for hard-copy printouts of test data, including time, date, and calculated results.
Engineering Excellence and Dual Testing Capacity:
The Model 1951 is equipped with advanced mechanical components to ensure standardized testing according to global pharmacopeial methods.
• Dual Stations and Drive: The equipment features two motorized platforms and uses a Direct Drive system with a Stepper Motor.
• Method Support: Supports both USP Method I and USP Method II testing protocols.
• Drop Height: The motorized platforms are designed to provide precise drop heights: 14 ± 2mm for the USP Method I version and 3 ± 0.2mm (or 3 ± 0.3mm as noted in some documentation) for the USP Method II version.
• Cylinder Compatibility: The platforms contain two cylinder holders with a snap-lock mechanism designed to securely accommodate both 100 ml and 250 ml cylinders.
• Optimized Tapping Motion: The simultaneous rotating and tapping motion minimizes any possible mass loss during the tapping down process, ensuring consistent and accurate results.
Applications:
The Tap Density Tester is critical in pharmaceutical quality control (QC), research and development (R&D), and formulation development, providing insights crucial for:
• Formulation development
• Powder flow studies and characteristics
• Compressibility assessments
• General quality control processes
• Optimizing tablet and capsule filling processes to ensure dosage uniformity
