Cole-Parmer Symmetry MB-T-50.H Moisture Analyzer Balance

Overview

The Cole-Parmer Symmetry MB-T-50.H Moisture Analyzer Balance is a high-resolution, integrated thermogravimetric instrument engineered for precise moisture content determination in solid and semi-solid samples via infrared-assisted drying and real-time mass loss monitoring. Unlike standalone analytical balances or conventional oven-dry methods, the MB-T-50.H combines precision weighing (0.0001 g readability) with controlled IR heating (up to 160 °C) in a single, compact enclosure—enabling direct, operator-independent calculation of moisture %, dry weight %, and weight loss kinetics without manual data transcription or post-processing. Its design adheres to thermogravimetric principles defined in ASTM D4442, ISO 1189, and USP , ensuring methodological alignment with pharmaceutical, food, polymer, and quality control laboratories requiring regulatory-compliant moisture analysis.

Key Features

• High-resolution weighing system with 50 g maximum capacity and 0.1 mg readability, calibrated via external standard weights for traceable accuracy.
• Optimized infrared drying chamber with uniform radiant heat distribution, eliminating hot spots and reducing drying time by up to 40% compared to halogen-based systems.
• Four preconfigured drying profiles—Standard, Rapid, Gentle, and Step—each programmable for ramp/hold temperature sequences and dynamic endpoint detection.
• Capacitive 4.25″ × 2.5″ color touchscreen interface with customizable menu layouts, supporting 11 on-screen and print languages for multinational lab environments.
• Dual infrared proximity sensors mounted at screen edges enable fully contactless operation—ideal for sterile workflows, glovebox integration, or high-contamination-risk samples.
• Comprehensive environmental compensation: adjustable air filter flow rate (Fast/Slow mode) mitigates draft-induced drift in non-climate-controlled labs.
• Integrated GLP diagnostic suite generates timestamped balance summary reports—including stability flags, calibration history, user ID, ambient temperature/humidity logs, and error root-cause indicators.

Sample Compatibility & Compliance

The MB-T-50.H accommodates diverse sample types including powders (pharmaceutical actives, excipients), granules (food ingredients, catalysts), films (polymer coatings), and hygroscopic solids (salts, dried botanicals). Its 3.5-inch stainless-steel weighing pan and shallow chamber geometry support rapid thermal equilibration and minimize edge effects during IR exposure. All firmware and data handling routines comply with FDA 21 CFR Part 11 requirements for electronic records and signatures, including audit trail activation, role-based user permissions (admin/operator/observer), and immutable data logging. Export/import functions via USB flash drive support structured data exchange compliant with LIMS and ELN systems, while encrypted database storage ensures integrity of up to 200 user-defined drying protocols.

Software & Data Management

Data capture and reporting are managed through an embedded operating system supporting multi-database architecture: Product, User, Packaging, Customer, Drying Protocol, Environmental Log, Report Archive, and Weighing History. Each record includes metadata such as operator ID, timestamp, ambient conditions (T/HR), drying profile parameters, final moisture result (% w/w), and statistical repeatability (n=3 RSD ≤ 0.5%). Reports export in PDF or CSV format with configurable headers and footers—including laboratory seal, QA approval fields, and instrument serial number. Network connectivity (Ethernet/Wi-Fi/RS-232/USB) enables seamless integration with enterprise-quality management systems and supports scheduled automatic report push to shared network drives or cloud repositories.

Applications

This analyzer serves critical QC/QA functions across regulated and research-intensive sectors: quantifying residual solvents in lyophilized biologics per ICH Q5C; verifying moisture limits in tablet formulations (USP ); assessing hygroscopicity of battery cathode materials; validating drying endpoints in spray-dried food powders; and performing routine moisture checks in polymer resin batches prior to extrusion. Its ability to store and recall 200 distinct drying methods—each with unique temperature ramps, hold durations, and termination criteria—makes it suitable for labs managing heterogeneous sample portfolios under evolving SOPs.

FAQ

What calibration standards are required for daily verification?
External calibration using Class M1 or better certified weights (e.g., 10 g and 50 g) is mandatory before first use and after any relocation or significant environmental change.
Can the drying temperature be adjusted beyond 160 °C?
No—the IR emitter and thermal shielding are rated for safe operation up to 160 °C; exceeding this limit voids warranty and compromises sensor longevity.
Is the instrument compatible with third-party LIMS software?
Yes—ASCII-formatted output via RS-232 or TCP/IP (Ethernet/Wi-Fi) supports standard SCPI and HL7-compatible parsing; configuration templates available upon request.
How does the system determine drying endpoint automatically?
It monitors mass change rate (Δm/Δt) over user-defined intervals; endpoint is triggered when the rate falls below a programmable threshold (e.g., 0.1 mg/min for 60 s) or reaches a fixed time limit.
Does the balance meet ISO/IEC 17025 traceability requirements?
When used with NIST-traceable calibration weights and documented environmental logs, the MB-T-50.H satisfies measurement uncertainty budgeting requirements for accredited testing laboratories.
