Overview
The Mettler Toledo PM4800 is a high-precision analytical balance engineered for laboratories requiring consistent mass measurement performance at the 0.1 mg readability level. Designed and manufactured in Switzerland, the PM4800 operates on electromagnetic force compensation (EMFC) principle—ensuring stable, drift-free readings under variable environmental conditions. Its robust monolithic weighing cell, integrated draft shield, and automatic internal calibration system (with optional external weight verification) deliver long-term repeatability and traceable accuracy compliant with ISO/IEC 17025 requirements. This refurbished unit has undergone full functional validation—including linearity, eccentricity, repeatability, and sensitivity tests—performed in accordance with Mettler Toledo’s service protocols at SpectraLab Scientific’s ISO 9001-certified refurbishment facility.
Key Features
- Readability of 0.1 mg across a 220 g maximum capacity, optimized for pharmaceutical QC, reference standard weighing, and formulation development.
- Integrated SmartSens infrared sensor for hands-free door control and draft shield operation—reducing mechanical wear and contamination risk.
- Internal calibration routine triggered automatically at user-defined intervals or temperature thresholds (±1.5 °C), ensuring continuous metrological integrity.
- RS232 and USB interfaces standard; optional Ethernet and Bluetooth modules available for networked lab environments.
- Multi-language touchscreen interface (English, German, French, Spanish, Chinese) with intuitive icon-driven navigation and GLP-compliant printout templates.
- Stainless steel pan and base construction with IP54-rated enclosure for resistance to dust and incidental liquid exposure.
Sample Compatibility & Compliance
The PM4800 accommodates standard analytical sample vessels—including weighing boats, crucibles, and volumetric flasks—within its 190 mm diameter weighing chamber. Its draft shield design minimizes convective air currents without restricting access during tare or sample placement. All refurbished units are verified against ASTM E898-22 (Standard Practice for Calibration of Analytical Balances) and meet the minimum performance criteria outlined in USP “Weights and Balances” for Class I and II applications. Each instrument ships with a Certificate of Inspection documenting as-found/as-left test results, including uncertainty budgets per EURAMET cg-18 guidelines. Units are pre-configured for compliance with FDA 21 CFR Part 11 when connected to validated LIMS or ELN systems via secure data export protocols.
Software & Data Management
The PM4800 supports direct integration with Mettler Toledo’s LabX™ software (v3.10 or later) for centralized instrument management, audit-trail-enabled data capture, and automated report generation. All refurbished instruments include licensed LabX Lite functionality—enabling user-level password protection, customizable SOP workflows, and electronic signature support. Raw measurement data exports in CSV, XML, or PDF formats with embedded metadata (timestamp, operator ID, environment log, calibration status). Audit trails record all critical events—including parameter changes, calibration actions, and user logins—with immutable timestamps aligned to NIST-traceable time servers. Data integrity safeguards comply with ALCOA+ principles and are routinely validated during GxP audits.
Applications
- Pharmaceutical quality control: active pharmaceutical ingredient (API) assay, excipient blending verification, and stability study sample preparation.
- Academic research labs: gravimetric analysis, stoichiometric reagent preparation, and nanomaterial dispersion quantification.
- Contract testing organizations (CTOs): method transfer support for compendial assays requiring <0.1% RSD precision per USP .
- Food & beverage laboratories: moisture content determination via loss-on-drying (LOD), nutritional labeling compliance, and allergen threshold verification.
- Environmental testing labs: filter weighing for particulate matter (PM2.5/PM10) analysis per EPA Method IO-4.2 and ISO 12103-1.
FAQ
Is this unit supplied with a valid calibration certificate?
Yes—each PM4800 undergoes full metrological verification prior to shipment and includes a traceable Certificate of Inspection signed by a certified Metrologist.
Can the balance be connected to our existing LIMS?
Absolutely—the RS232 and USB ports support ASCII-based data streaming compatible with most LIMS vendors; LabX middleware provides additional ODBC and API-level integration options.
What does the 6-month warranty cover?
The warranty covers parts and labor for defects in materials or workmanship under normal laboratory use, excluding damage from misuse, unauthorized modification, or environmental factors outside specified operating conditions (15–30 °C, ≤80% RH non-condensing).
Are original accessories included?
Yes—each unit ships with its original draft shield, stainless steel pan, leveling feet, calibration weights (if applicable), power supply, and printed user manual.
Do you offer installation and qualification services?
SpectraLab Scientific provides IQ/OQ documentation packages and on-site installation support upon request—aligned with ISO/IEC 17025 and GMP Annex 15 requirements.
