Overview
The AND GF-10002A Precision Electronic Balance is an industrial-grade analytical weighing instrument engineered for high-reproducibility mass measurement in quality control laboratories, pharmaceutical manufacturing environments, and materials testing facilities. Designed and manufactured in Japan under strict A&D (A&D Company, Ltd.) quality management systems, the GF-10002A operates on electromagnetic force compensation (EMFC) principle—ensuring linear response, minimal drift, and long-term stability across its full 10,200 g capacity range. With a readability of 0.01 g and repeatability consistently maintained at ±0.01 g under standard laboratory conditions (20 ±2 °C, <60% RH, vibration-isolated bench), this balance meets the performance requirements for routine calibration verification, formulation batching, and raw material acceptance testing per ISO/IEC 17025 and USP . Its compact low-profile housing (93 mm height) and reinforced stainless-steel weighing pan (165 × 165 mm) support ergonomic integration into fume hoods, glove boxes, or automated dispensing workstations.
Key Features
- Electromagnetic force compensation (EMFC) sensor architecture with auto-zero tracking and temperature-compensated digital filtering
- External calibration capability using certified weights traceable to NIST or JCSS standards; supports multi-point calibration verification
- Fast stabilization time: ≤1.0 second for loads ≥50 g, enabling throughput optimization in high-volume QC workflows
- Robust mechanical design compliant with IP42 ingress protection rating for resistance to dust and incidental splashes
- Integrated RS-232 and USB Device interfaces for direct connection to LIMS, ERP, or statistical process control (SPC) software
- GLP/GMP-compliant data output with optional timestamp, operator ID, and balance serial number embedding
- Programmable application modes including parts counting, percent weighing, density determination (with optional kit), and checkweighing
Sample Compatibility & Compliance
The GF-10002A accommodates heterogeneous solid samples—including powders, granules, metal components, and packaged reference standards—within its large 165 × 165 mm stainless-steel pan. Its low center-of-gravity chassis minimizes sensitivity to air currents and floor vibrations, making it suitable for non-air-conditioned production floors where environmental control is limited. The instrument conforms to international metrological standards including JIS B 7721 (Japanese Industrial Standard for non-automatic weighing instruments), ISO 9001:2015 (quality management), and ASTM E898–18 (standard guide for selection and use of laboratory balances). While not FDA 21 CFR Part 11–validated out-of-the-box, its audit-trail-ready data export functionality supports validation protocols required for regulated pharmaceutical and medical device manufacturing.
Software & Data Management
Data acquisition is supported via built-in communication protocols compatible with industry-standard software platforms such as LabX (Mettler Toledo), WinCT (A&D’s legacy suite), and custom Python/Node.js-based middleware. All weight readings include embedded metadata: date/time stamp (real-time clock), balance ID, calibration status flag, and user-defined sample ID. Optional firmware upgrades enable CSV-formatted batch exports with column headers aligned to ASTM E2500-21 data integrity guidelines. For GxP environments, system configuration logs and calibration history can be exported in PDF or XML format with digital signature support when integrated with validated electronic lab notebook (ELN) systems.
Applications
- Raw material and finished product weight verification in ISO 13485-certified medical device manufacturing
- Batch release testing of active pharmaceutical ingredients (APIs) per ICH Q5C and USP
- Calibration of secondary reference standards in metrology labs accredited to ISO/IEC 17025
- Gravimetric analysis of catalyst loading, polymer blends, and composite formulations
- Quality assurance of packaging fill weights in food and beverage production lines
- Teaching and research applications in university chemistry and materials science laboratories
FAQ
What is the recommended calibration frequency for the GF-10002A in a GLP environment?
Calibration should be performed before first use, after relocation, following any impact or overload event, and at defined intervals—typically daily or per shift—documented in a formal calibration log per ISO/IEC 17025 clause 6.5.
Does the GF-10002A support internal calibration?
No—it requires external calibration using class M2 or better certified weights; internal motorized calibration is not implemented in this model series.
Can the balance interface with a networked LIMS without additional hardware?
Yes—via its native RS-232 port with standard ASCII command protocol (A&D AD-4826); Ethernet or Wi-Fi connectivity requires an external serial-to-Ethernet converter.
Is the weighing pan removable for cleaning?
Yes—the stainless-steel pan is tool-free detachable and autoclavable up to 121°C for sterile processing environments.
What environmental conditions are required to maintain stated repeatability?
Ambient temperature stability within ±2°C of 20°C, relative humidity below 60% non-condensing, and absence of magnetic fields exceeding 400 A/m or airflow >0.2 m/s across the pan surface.
