Overview
The METTLER TOLEDO MA54 Analytical Balance is a precision laboratory instrument engineered for high-reproducibility mass measurement in routine analytical workflows. Operating on electromagnetic force compensation (EMFC) principle, it delivers stable and drift-compensated readings with resolution down to 0.1 mg (depending on model variant), suitable for applications requiring compliance with ISO/IEC 17025, USP , and ASTM E898-20 standards. Designed for environments where operator efficiency, data integrity, and long-term stability are critical—including QC laboratories, academic research settings, and pharmaceutical manufacturing support—the MA54 integrates robust mechanical architecture with intuitive human-machine interaction. Its sealed electromagnetic sensor, draft shield-compatible design, and temperature-compensated internal calibration system ensure consistent performance across variable ambient conditions typical of multi-shift lab operations.
Key Features
- High-brightness, backlit LCD display with contextual on-screen guidance—providing step-by-step prompts for tare, weighing, percentage calculation, density determination, and net/gross mode selection.
- Touch-sensitive control panel with tactile feedback; optimized layout minimizes accidental input and supports gloved-hand operation.
- Internal calibration with motorized built-in test weights—enabling automated recalibration at user-defined intervals or upon temperature drift detection (±1.5 °C threshold).
- Dual communication interface: RS232 port for legacy printer or PC connectivity and USB-A host port supporting direct connection to USB flash drives, label printers, or HID-compliant peripherals without driver installation.
- Chemically resistant glass weighing pan and reinforced polymer housing—designed for resistance to common solvents, cleaning agents, and mechanical abrasion during daily decontamination cycles.
- Auto-stabilization algorithm with adjustable settling time (0.5–3 s), configurable via service menu to accommodate vibration-prone benchtop locations.
Sample Compatibility & Compliance
The MA54 accommodates standard analytical sample containers including weighing boats, vials, crucibles, and filter papers within its 54 g maximum capacity. The integrated draft shield (sold separately as optional accessory) ensures metrological stability for low-mass measurements (<100 mg) under non-laminar airflow conditions. All firmware and hardware configurations comply with GLP/GMP documentation requirements: full audit trail logging (user ID, timestamp, action type, before/after values) is enabled when connected to METTLER TOLEDO LabX Lite software or compatible LIMS systems. Device firmware adheres to IEC 61326-1 (EMC) and IEC 61010-1 (safety) standards; calibration certificates traceable to NIM (National Institute of Metrology, China) or PTB (Physikalisch-Technische Bundesanstalt) are available upon request.
Software & Data Management
While the MA54 operates autonomously via front-panel interface, it supports seamless integration into regulated digital workflows. Raw weighing data—including date/time stamp, operator ID (if configured), unit, and result—can be exported in CSV or TXT format directly to USB storage. When paired with METTLER TOLEDO’s free LabX Lite software (Windows-based), users gain access to electronic signature capability, customizable report templates, and automatic backup to network drives. For environments governed by FDA 21 CFR Part 11, full compliance requires deployment of LabX Professional with role-based access control, electronic audit trail archiving, and secure user authentication—configurations validated per IQ/OQ protocols.
Applications
- Pharmaceutical formulation: active pharmaceutical ingredient (API) dispensing, excipient ratio verification, and batch release testing per USP general chapters.
- Academic chemistry labs: stoichiometric reagent preparation, gravimetric analysis, and calibration of volumetric glassware.
- Materials science: powder density determination, catalyst loading quantification, and thin-film mass monitoring pre/post thermal treatment.
- Food & beverage QA: moisture content assessment via loss-on-drying (LOD), nutritional labeling compliance checks, and raw material acceptance testing.
- Environmental testing labs: filter weight analysis for particulate matter (PM2.5/PM10) quantification in air sampling protocols.
FAQ
What is the readability and maximum capacity of the MA54 Analytical Balance?
The MA54 offers 0.1 mg readability with a 54 g maximum capacity. Exact specifications may vary slightly depending on factory configuration and regional regulatory certification.
Does the MA54 support internal calibration with traceable standards?
Yes—it features an automated internal calibration system using factory-traceable test weights, compliant with ISO 9001 and ISO/IEC 17025 internal calibration requirements.
Can the MA54 be connected to a laboratory information management system (LIMS)?
Direct LIMS integration is achieved via RS232 or USB serial emulation mode, provided the LIMS supports ASCII-based weighing data ingestion protocols.
Is the MA54 suitable for use in ISO Class 5 cleanrooms?
When equipped with optional static-dissipative draft shield and operated with validated cleaning procedures, the MA54 meets mechanical and electrostatic discharge (ESD) requirements for ISO 14644-1 Class 5 environments.
How often should routine performance verification be conducted?
METTLER TOLEDO recommends daily zero-point verification and weekly accuracy checks using certified reference weights—frequency may increase based on risk assessment per ISO/IEC 17025 clause 6.5.
