Overview
The Mettler Toledo AG245 Analytical Balance is a high-precision, microprocessor-controlled weighing instrument engineered for laboratory environments requiring reproducible mass measurements in the sub-milligram range. Based on electromagnetic force compensation (EMFC) technology, the AG245 delivers stable, drift-compensated readings with resolution down to 0.01 mg (10 µg) and maximum capacity of 245 g. Designed and manufactured in Switzerland, it complies with international metrological standards including OIML R76 and adheres to ISO 9001 quality management systems. This refurbished unit has undergone full functional validation—including linearity, repeatability, eccentricity, and sensitivity testing—performed by SpectraLab Scientific’s ISO/IEC 17025-accredited calibration laboratory. All mechanical and electronic subsystems—including the draft shield, load cell, internal calibration weight, and temperature-compensated electronics—have been inspected, cleaned, and verified against factory specifications.
Key Features
- Electromagnetic force compensation (EMFC) transducer architecture ensuring long-term stability and minimal thermal drift
- Internal motorized calibration routine with built-in reference weight (class E2), supporting automatic recalibration at user-defined intervals or ambient temperature shifts ≥1.5 °C
- Integrated draft shield with dual sliding doors and static-dissipative glass panels, reducing air current interference during ultra-low-mass measurements
- RS232 and USB interfaces compliant with METTLER TOLEDO Standard Protocol (MT-SPP) for seamless integration with LIMS and ELN platforms
- Multi-language display (English, German, French, Spanish, Chinese) and intuitive menu navigation via capacitive touch keys
- GLP/GMP-compliant data logging: timestamped weight records with operator ID, balance ID, and environmental metadata (temperature, humidity if external sensor connected)
Sample Compatibility & Compliance
The AG245 accommodates standard analytical sample containers—including weighing boats, crucibles, vials, and filter papers—within its 120 mm diameter pan. Its compact footprint (210 × 320 × 330 mm) and low-profile design enable integration into fume hoods and glove boxes. The balance meets regulatory requirements for quantitative analytical workflows under USP , EP 2.1.6, and ASTM E898–22. All refurbished units are supplied with a Certificate of Conformance (CoC) and a Traceable Calibration Report referencing NIST-traceable standards. Optional compliance upgrades include 21 CFR Part 11–enabled software modules for audit trail generation and electronic signature support.
Software & Data Management
The AG245 supports native communication via MT-SPP over RS232 or USB Virtual COM port. When connected to PC-based applications such as LabX Lite or third-party SCADA/LIMS systems, it transmits real-time weight data with configurable formatting (e.g., CSV, ASCII, XML). Built-in memory stores up to 1,000 measurement records with time/date stamps and optional user authentication tags. For regulated environments, SpectraLab offers optional firmware updates enabling full 21 CFR Part 11 compliance—including role-based access control, immutable audit trails, and electronic signatures—validated per IQ/OQ protocols.
Applications
- Pharmaceutical formulation: active pharmaceutical ingredient (API) dispensing, excipient ratio verification, and content uniformity testing per USP
- Academic and industrial research: gravimetric preparation of standard solutions, catalyst loading quantification, and thermogravimetric sample taring
- Quality control laboratories: raw material identity confirmation, batch release testing, and stability study sample weighing
- Environmental testing labs: filter paper mass differential analysis for particulate matter (PM2.5/PM10) determination per EPA Method 201A
- Materials science: powder density characterization, coating thickness calculation via mass-thickness correlation, and nanomaterial dispersion quantification
FAQ
Is this AG245 unit factory-refurbished or dealer-refurbished?
This unit is professionally refurbished by SpectraLab Scientific following METTLER TOLEDO’s recommended service procedures, including full mechanical inspection, EMFC recalibration, and firmware update to latest stable release.
Does the 6-month warranty cover parts and labor globally?
Yes—the warranty includes onsite or return-to-lab repair coverage for all functional components; international service coordination is supported through our network of authorized METTLER TOLEDO service partners.
Can I obtain a full calibration certificate with uncertainty budget?
Upon request, SpectraLab issues an ISO/IEC 17025-accredited calibration certificate (traceable to NIST or PTB) including expanded uncertainty (k=2) for both linearity and repeatability at defined test points.
Is the original AC adapter and draft shield included?
Yes—all original accessories shipped with the AG245—including power supply, draft shield assembly, leveling feet, calibration weight, and user manual—are included and verified functional.
What documentation accompanies the instrument?
Each unit ships with a refurbished instrument checklist, calibration report, Certificate of Conformance, packing list, and digital copy of the AG245 Operating Manual (v5.30 or later).
