Overview
The A&D GF10001A Precision Balance is a high-stability, industrial-grade weighing instrument engineered for reproducible mass measurement in regulated laboratory, quality control, and production environments. Designed and manufactured in Japan by A&D Company, Ltd.—a globally recognized leader in metrological instrumentation—the GF10001A operates on electromagnetic force restoration (EMFR) principle, ensuring linearity, long-term stability, and immunity to gravitational drift across extended operation cycles. With a maximum capacity of 10,200 g and readability of 0.1 g, it bridges the functional gap between analytical and top-loading balances, supporting applications requiring robustness without compromising traceable accuracy. Its compact low-profile chassis (212 × 317 × 93 mm) accommodates integration into confined workspaces or automated material handling systems, while the 165 × 165 mm stainless-steel weighing pan provides mechanical resilience against repeated loading and cleaning protocols.
Key Features
- Impact Shock Detection (ISD): Real-time monitoring of mechanical disturbance during weighing; triggers audible/visual alert when acceleration exceeds user-defined thresholds—critical for validating process integrity in inline packaging or assembly lines.
- Automatic Minimum Weight Assessment (APA): Proprietary ECL (Enhanced Calibration Logic) algorithm dynamically evaluates repeatability under actual operating conditions and calculates the smallest valid sample mass per USP and EUR Pharm 2.1.6 guidelines.
- Flow Rate Display (FRD): Enables real-time calculation and visualization of mass flow (g/s or g/min) for liquid dispensing, powder transfer, or gravimetric feeding systems—eliminating need for external flow meters in controlled dosing workflows.
- Dual Communication Interface: Simultaneous RS-232C and USB-B ports support concurrent connection to PCs, printers, PLCs, or barcode scanners—enabling bidirectional command execution (e.g., tare-on-trigger, print-on-stable) and seamless integration into LIMS or MES platforms.
- Environmental Compensation (GX-A series only): Integrated temperature sensor initiates automatic internal recalibration when ambient drift exceeds ±1°C from last calibration point—maintaining metrological validity without operator intervention.
- User Permission Management: Configurable access levels for up to 11 users—including administrator, technician, and operator roles—with password protection and audit-trail–enabled actions aligned with FDA 21 CFR Part 11 requirements.
Sample Compatibility & Compliance
The GF10001A supports both standard above-pan and below-pan (hook) weighing configurations via included mounting hardware, enabling density determination (with optional density kit), net/gross/tare operations, and dynamic load monitoring. Its construction meets IP42 ingress protection standards for resistance to dust and incidental splashes. All firmware and data logging functions comply with GLP, GMP, and ISO/IEC 17025 documentation requirements: timestamps, operator ID, calibration history, and measurement metadata are embedded in every exported record. Data export formats include CSV, TXT, and configurable GLP/GMP reports with header fields compliant with Annex 11 and ALCOA+ principles.
Software & Data Management
Internal memory stores up to 200 measurement records, 50 calibration logs, and 50 unit-mass references—each timestamped and tagged with user ID. Data export supports automatic transmission upon stabilization or manual trigger, with configurable delimiter, decimal separator, and field order. Optional A&D WinCT software enables remote configuration, statistical process control (SPC) charting, trend analysis, and electronic signature capture. Audit trail functionality logs all critical events—including parameter changes, calibration attempts, and user logins—with immutable timestamps and operator attribution—fully satisfying FDA 21 CFR Part 11 electronic record requirements.
Applications
- Pharmaceutical QC: Batch release testing, active pharmaceutical ingredient (API) dispensing, excipient blending verification, and uniformity-of-weight assessment per USP .
- Food & Beverage: Recipe formulation, portion control validation, raw material intake reconciliation, and HACCP-critical weigh points.
- Chemical Manufacturing: Catalyst charge verification, solvent addition control, and reaction stoichiometry confirmation.
- Academic & Industrial Research: Gravimetric sorption studies, thermal mass loss profiling (TGA pre-screening), and material density characterization.
- Logistics & Packaging: Pallet load verification, shipping label weight validation, and returnable container reconciliation.
FAQ
Does the GF10001A support internal calibration?
No—the GF10001A is an externally calibrated model (GF-series); internal calibration is available only on GX-series instruments.
Is density determination possible with this model?
Yes—when paired with the optional A&D AD-1673 density determination kit, the GF10001A performs solid and liquid density measurements per ASTM D792 and ISO 1183.
Can the balance operate on battery power?
An optional rechargeable lithium-ion battery pack (AD-1685) is available, providing up to 8 hours of continuous operation without AC input.
What regulatory standards does its data output satisfy?
All exported data includes mandatory GLP/GMP headers (date/time, operator ID, balance ID, calibration status), conforms to ISO/IEC 17025 reporting structure, and supports 21 CFR Part 11 compliance when used with WinCT software and appropriate system controls.
Is the RS-232 interface compatible with modern Windows OS versions?
Yes—USB-to-RS-232 adapters (including A&D’s AD-1676) ensure plug-and-play compatibility with Windows 10/11, macOS, and Linux-based hosts using standard virtual COM port drivers.
