Overview
The METTLER TOLEDO XS8001S Precision Balance is an industrial-grade weighing instrument engineered for high-throughput laboratory and production environments where speed, reliability, and ergonomic safety are critical. Operating on electromagnetic force compensation (EMFC) technology, the XS8001S delivers rapid stabilization—typically within 1 second—while maintaining a readability of 0.1 g across its full 8.1 kg capacity. Its robust mechanical architecture integrates a monolithic load cell design with advanced digital filtering algorithms to suppress environmental disturbances such as air currents, floor vibrations, and thermal drift. Unlike analytical balances optimized for sub-milligram resolution, the XS8001S is purpose-built for routine mass determination tasks in QC labs, formulation stations, and warehouse receiving areas—where reproducibility, ease of validation, and operator well-being are equally prioritized.
Key Features
- SmartPan™ weighing pan: Standard on all XS-series precision balances, this patented pan geometry minimizes aerodynamic interference—enabling stable readings even without draft shields in fume hoods or laminar flow cabinets.
- ErgoStand™ adjustable base: A height- and angle-adjustable support system designed to align the balance with optimal user posture, reducing musculoskeletal strain during prolonged operation—validated per ISO 11228-1 (ergonomics of manual handling).
- FACT (Fully Automatic Calibration Technology): Built-in motorized internal calibration mechanism activates automatically at predefined intervals or temperature thresholds (±1.5 °C), ensuring long-term traceability without manual intervention.
- Hygienic, service-friendly construction: Smooth, crevice-free surfaces; fully detachable SmartPan; integrated spill containment tray beneath the pan; and IP54-rated enclosure for resistance to dust and incidental liquid splashes.
- Large 16-mm digit display & QWERTY keypad: High-contrast LCD interface supports intuitive sample ID entry, batch logging, and real-time status feedback—reducing transcription errors and cognitive load.
Sample Compatibility & Compliance
The XS8001S accommodates diverse sample types—including powders, granules, liquids in containers, and irregularly shaped solids—within its 190 mm × 223 mm pan area. Its minimum weight (per USP ) is 82 g under typical lab conditions (k = 2, repeatability = 40 mg), making it suitable for applications governed by pharmaceutical compendial requirements. While not certified for legal-for-trade use, the balance meets ISO/IEC 17025 metrological criteria when operated within specified environmental limits (20 ± 5 °C, <70% RH, no direct sunlight or drafts). It supports GLP/GMP workflows via integrated TestManager firmware, which executes daily performance checks (e.g., repeatability, eccentricity, linearity) and stores audit-ready logs with timestamps and operator IDs.
Software & Data Management
The XS8001S operates natively with METTLER TOLEDO’s LabX® software platform—a secure, server-based solution compliant with FDA 21 CFR Part 11 and EU Annex 11. LabX enables SOP-driven weighing protocols, automatic calculation of net/gross/tare values, real-time statistical process control (SPC) charting, and seamless integration with LIMS or ERP systems via ODBC or RESTful API. All data—including raw measurements, calibration records, user actions, and electronic signatures—is encrypted, time-stamped, and immutably archived. The balance’s embedded TestManager performs automated verification routines and flags deviations against preconfigured tolerances, generating PDF reports for internal audits or regulatory inspections.
Applications
- Pharmaceutical: Raw material receipt inspection, bulk powder dispensing, tablet weight uniformity pre-checks, and excipient blending verification.
- Food & Beverage: Batch ingredient dosing, yield reconciliation, packaging weight compliance (e.g., EU Directive 2009/22/EC), and HACCP-critical checkpoint monitoring.
- Chemical Manufacturing: Catalyst charge verification, solvent addition control, and intermediate product release testing.
- Academic & Contract Research: Teaching labs requiring rugged, low-maintenance instrumentation; method development studies requiring high repeatability at 0.1 g resolution.
- Quality Control Labs: Routine stability testing, container closure integrity checks, and environmental sample preparation where throughput and ergonomics directly impact analyst retention.
FAQ
What is the minimum weight I can reliably weigh on the XS8001S according to USP standards?
The typical minimum weight is 82 g (k = 2, repeatability = 40 mg), calculated per USP . This value must be verified under your specific environmental and procedural conditions.
Does the XS8001S support external calibration with traceable weights?
Yes—it accepts external calibration using Class M2 or better certified weights. Internal FACT calibration supplements but does not replace periodic external verification required by ISO/IEC 17025.
Can the balance be integrated into a networked laboratory environment?
Yes—via Ethernet or USB, it connects to LabX servers or third-party systems using standard communication protocols (TCP/IP, RS-232, or USB HID). All network activity complies with IEEE 802.3 and TLS 1.2 encryption standards.
Is the XS8001S compliant with GxP data integrity requirements?
When used with LabX software and configured with appropriate access controls, audit trails, and electronic signatures, it satisfies ALCOA+ principles and supports 21 CFR Part 11 compliance.
How often should FACT calibration be performed?
FACT initiates automatically after power-on, after large temperature shifts (>1.5 °C), or at user-defined intervals (e.g., every 2 hours, daily, or weekly)—configurable via the touchscreen interface or LabX.
