Sartorius BSA224S-CW Analytical Balance

Overview

The Sartorius BSA224S-CW is a high-precision analytical balance engineered for routine laboratory weighing tasks requiring reproducibility, traceability, and operational robustness. Operating on electromagnetic force compensation (EMFC) principle, it delivers stable and drift-compensated measurements under variable environmental conditions—including minor air currents, temperature fluctuations, and mechanical vibrations. With a maximum capacity of 220 g and readability of 0.1 mg, the BSA224S-CW meets the performance requirements for quantitative analysis in pharmaceutical QC, academic research, chemical synthesis, and quality control laboratories governed by ISO 17025, USP , and ASTM E898 standards. Its compact footprint and integrated design minimize bench space usage while maintaining full compliance with Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) documentation expectations.

Key Features

• Motorized internal calibration system with automatic self-adjustment—activated via single-key operation to ensure ongoing metrological integrity without manual intervention.
• High-contrast backlit LCD display featuring 15 mm character height for optimal legibility under diverse ambient lighting conditions, including low-light or glare-prone environments.
• Dedicated built-in level indicator adjacent to the display—enabling immediate visual verification of instrument leveling prior to critical measurements.
• Intuitive user interface with five-language menu support (English, German, French, Spanish, Chinese) and context-sensitive soft-key navigation—reducing training time and minimizing operator-induced errors.
• RS-232C bidirectional communication port as standard; compatible with Sartorius YDP03-0CE printers and third-party data acquisition systems via optional USB-RS232 adapters.
• Preloaded application modes: percentage weighing, net weight summation, animal/dynamic weighing, unit conversion (g, mg, oz, ct, etc.), and arithmetic functions (multiplication and division).

Sample Compatibility & Compliance

The BSA224S-CW accommodates standard laboratory samples placed on its 90 mm diameter stainless steel weighing pan—suitable for powders, granules, liquids in tared containers, and small solid specimens. Its draft shield compatibility (sold separately) supports volatile or hygroscopic sample handling. All measurement data—including calibration logs, adjustment records, and timestamped weighings—can be exported with full audit trail capability when paired with GLP-compliant printers or validated LIMS/ELN software. The balance conforms to international regulatory frameworks including ISO 9001, ISO/IEC 17025, and FDA 21 CFR Part 11 when used with appropriate electronic signature and data integrity controls.

Software & Data Management

While the BSA224S-CW operates autonomously without external software, its RS-232C interface enables seamless integration into laboratory informatics ecosystems. When connected to Sartorius LabX Lite (freely available), users gain access to automated report generation, customizable templates, and structured export to CSV or PDF formats. All printed outputs include date/time stamps, operator ID fields (if configured), balance serial number, and calibration status—fulfilling essential requirements for audit-ready documentation. The device stores no internal database; instead, it transmits raw values and metadata in real time—ensuring data ownership remains with the host system and aligning with ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate) principles.

Applications

• Pharmaceutical formulation: precise active ingredient dosing during tablet development and stability testing.
• Chemical synthesis: stoichiometric reagent dispensing and yield calculation in R&D and pilot-scale reactions.
• Materials science: density determination via mass/volume correlation and particulate mass distribution analysis.
• Environmental testing labs: gravimetric analysis of filter residues (e.g., PM2.5, TSP) per EPA Method 201A and ISO 12103-1.
• Educational institutions: teaching fundamental metrology concepts including uncertainty estimation, repeatability assessment, and calibration hierarchy.

FAQ

Does the BSA224S-CW support external calibration with certified weights?
Yes—while motorized internal calibration is standard, the balance accepts external calibration using Class E2 or better reference weights via the “External Calibration” mode.
Is the RS-232C interface compatible with modern Windows/macOS systems?
Yes—when used with an approved USB-to-RS232 adapter (e.g., FTDI-based), the interface supports native COM port recognition and integration with Excel, LabX, or custom Python/Node.js scripts.
Can the display language be changed after installation?
Yes—the language setting is fully configurable through the setup menu and persists across power cycles.
What environmental conditions are recommended for optimal performance?
Operate within 15–30 °C ambient temperature, ≤80% non-condensing relative humidity, and on a vibration-isolated, level surface away from HVAC vents and electromagnetic sources.
Is the BSA224S-CW suitable for GxP-regulated environments?
Yes—when deployed with documented procedures, periodic verification, and appropriate data capture tools (e.g., LabX or validated printer), it satisfies core requirements for data integrity and instrument qualification per ICH Q7 and Annex 11.
