Metler Toledo PB3002 Precision Analytical Balance

Overview

The Mettler Toledo PB3002 is a high-precision analytical balance engineered for laboratory environments requiring consistent mass measurement performance at the 0.001 g (1 mg) readability level. Designed and manufactured in Switzerland, the PB3002 operates on electromagnetic force compensation (EMFC) technology—ensuring stable, drift-free readings with rapid stabilization time (<3 s) and high reproducibility across repeated measurements. Its robust monolithic weighing cell architecture minimizes mechanical hysteresis and thermal drift, making it suitable for routine QC testing, formulation work, sample preparation, and gravimetric analysis in pharmaceutical, academic, and industrial laboratories. This unit is a certified pre-owned instrument, fully refurbished and functionally validated by SpectraLab Scientific to meet original factory specifications prior to resale.

Key Features

• Readability: 1 mg (0.001 g) with maximum capacity of 3,200 g — optimized for mid-range analytical and semi-micro applications
• Integrated draft shield with sliding glass doors to mitigate air-current interference during sensitive weighing
• RS232 serial interface for direct data transfer to LIMS, Excel, or custom QA software; compatible with METTLER TOLEDO’s LabX Lite (legacy support)
• Internal calibration routine with built-in weight verification; supports external calibration using traceable Class E2 standard masses
• Stainless steel pan and housing for corrosion resistance and ease of decontamination
• Leveling feet with integrated bubble vial and auto-leveling indicator for rapid setup validation
• Compliance-ready design: Supports audit trails when connected to compliant data systems; meets foundational requirements for GLP and GMP documentation workflows

Sample Compatibility & Compliance

The PB3002 accommodates standard weighing vessels including crucibles, beakers, filter papers, and tare containers up to 150 mm in diameter. Its open pan geometry allows straightforward handling of powders, granules, and small solid samples. While not intrinsically rated for hazardous or explosive atmospheres, the balance complies with IEC 61010-1 safety standards for laboratory electrical equipment. All refurbished units undergo full functional verification per ISO 9001 and ISO/IEC 17025-aligned procedures—including repeatability (≤±0.002 g at full load), eccentricity (≤±0.003 g), and linearity (≤±0.004 g) tests. Calibration certificates—traceable to NIST or PTB equivalents—are provided upon request for regulatory submissions.

Software & Data Management

The PB3002 supports ASCII-based data output via RS232, enabling seamless integration into regulated environments where electronic records must satisfy FDA 21 CFR Part 11 requirements. When paired with validated third-party data capture tools (e.g., LabWare LIMS, Thermo Fisher SampleManager), the balance contributes to ALCOA+ compliant data integrity frameworks—ensuring attributable, legible, contemporaneous, original, and accurate records. Though the PB3002 lacks native Ethernet or USB connectivity, its serial protocol is widely supported by legacy lab automation systems. SpectraLab provides configuration guidance and interface validation templates for customers implementing 21 CFR Part 11-compliant workflows.

Applications

• Pharmaceutical: Active pharmaceutical ingredient (API) dispensing, excipient blending verification, and dissolution sample preparation
• Academic Research: Stoichiometric reagent weighing, catalyst loading, and gravimetric standard solution preparation
• Materials Science: Powder density determination, coating mass uniformity assessment, and ash content analysis
• Food & Agriculture: Moisture loss-on-drying (LOD) calculations, nutrient fortification dosing, and reference standard preparation
• Environmental Testing: Filter weight gain analysis for particulate matter (PM₁₀/PM_2.5) quantification per EPA Method 201A

FAQ

Is this PB3002 unit factory-calibrated and certified?
Yes—each unit undergoes full metrological verification against traceable standards before shipment. A calibration report (non-accredited) is included; accredited certification per ISO/IEC 17025 is available as an optional add-on.
What does the 6-month warranty cover?
The warranty covers defects in materials and workmanship under normal laboratory use, including the weighing cell, display module, and internal electronics. It excludes damage from misuse, improper installation, or unauthorized modification.
Can this balance be integrated into a GxP-regulated environment?
Yes—when used with validated data capture software and documented SOPs, the PB3002 meets foundational requirements for data integrity and instrument qualification (IQ/OQ) under FDA and EMA guidelines.
Are replacement parts and service support available post-purchase?
SpectraLab maintains an inventory of genuine METTLER TOLEDO spare components (draft shields, leveling feet, interface boards) and offers remote technical support for troubleshooting and preventive maintenance scheduling.
