Overview
The Mettler Toledo AE50, AE163, and AE200 analytical balances represent a generation of high-precision mass measurement instruments engineered for laboratory environments requiring repeatability, traceability, and long-term stability. These models operate on electromagnetic force compensation (EMFC) principle—where the mass-induced deflection of a precision load cell is counterbalanced by a controlled electromagnetic current, enabling direct digital readout with microgram-level resolution. Designed and manufactured in Switzerland, each unit conforms to international metrological standards including OIML R76, ISO/IEC 17025, and EU Directive 2014/32/EU (Measuring Instruments Directive). Though classified as pre-owned, all units undergo full functional validation at SpectraLab Scientific’s ISO 9001-certified refurbishment facility—including linearity, eccentricity, repeatability, and sensitivity tests—prior to release. Units are not merely cleaned and resold; they are recalibrated using NIST-traceable standards, and mechanical components (draft shield hinges, leveling feet, pan supports) are inspected and replaced where wear exceeds manufacturer-specified tolerances.
Key Features
- Electromagnetic force compensation (EMFC) sensor architecture ensuring high reproducibility and minimal drift over time
- Internal calibration routine with motorized weight actuation (AE163/AE200); manual calibration option available on AE50
- Integrated draft shield with ergonomic sliding doors (standard on AE163/AE200; optional on AE50)
- RS232 interface for data export to LIMS or Excel-compatible software; compatible with Mettler Toledo LabX legacy drivers
- Stainless steel weighing pan and base construction for chemical resistance and cleanroom compatibility
- Leveling indicators and adjustable foot screws for rapid setup on standard lab benches
- Auto-zero tracking and automatic internal adjustment to ambient temperature fluctuations
Sample Compatibility & Compliance
These balances accommodate standard analytical sample containers (weighing boats, vials, crucibles) up to 200 mm in diameter. The AE50 (50 g capacity, 0.01 mg readability), AE163 (160 g, 0.1 mg), and AE200 (200 g, 0.1 mg) cover common QC/QA and research workflows in pharmaceutical, academic, and materials science labs. Each instrument ships with full documentation of post-refurbishment verification—including calibration certificates with uncertainty budgets, test reports per ASTM E898-22 (Standard Guide for Validation of Analytical Balances), and conformity statements aligned with GLP and GMP Annex 15 requirements. All units meet Class I accuracy per EN 45501 and support audit-ready operation under FDA 21 CFR Part 11 when paired with compliant data acquisition software.
Software & Data Management
While these models do not feature built-in touchscreen interfaces or cloud connectivity, their RS232 output enables seamless integration into regulated environments via third-party data capture tools such as LabWare LIMS, Thermo Fisher SampleManager, or custom Python-based logging scripts. SpectraLab provides configuration templates for ASCII data formatting (including timestamp, stable indicator flag, and unit code), ensuring compliance with ALCOA+ data integrity principles. Optional firmware updates (where applicable and validated) can be applied prior to shipment to address known communication protocol anomalies reported in earlier AE-series revisions.
Applications
- Quantitative preparation of reference standards and working solutions in pharmaceutical QC labs
- Weighing of catalysts, nanoparticles, and thin-film substrates in materials R&D
- Dispensing verification in automated liquid handling system qualification (IQ/OQ)
- Educational use in university chemistry and engineering laboratories requiring ISO-compliant instrumentation
- Environmental testing labs performing filter weighing for PM2.5/PM10 particulate analysis

FAQ
Are these balances supplied with valid calibration certificates?
Yes—each unit includes a post-refurbishment calibration certificate issued by SpectraLab’s accredited metrology team, traceable to NIST or PTB standards, with documented measurement uncertainty.
Can I request installation and operational qualification (IQ/OQ) support?
SpectraLab offers optional IQ/OQ protocol development and on-site execution services, aligned with USP , ASTM E2500, and EU GMP Annex 15 guidelines.
Is firmware upgrade included in the refurbishment process?
Firmware updates are performed only where technically validated and documented; unsupported or beta versions are never installed.
What is the expected lifetime after refurbishment?
Based on usage history (≤4 years, moderate lab duty cycle), remaining service life typically exceeds 5 additional years with scheduled maintenance every 12–18 months.
Do you provide spare parts and technical documentation?
Yes—service manuals, schematics, and consumables (draft shields, leveling feet, pan assemblies) are available under separate quotation upon request.
