Overview
The Sartorius QUINTIX124-1CN is a high-performance analytical balance engineered for precision mass measurement in regulated laboratory environments. It operates on electromagnetic force compensation (EMFC) technology—a principle widely adopted in modern analytical balances—where the sample’s weight is counterbalanced by an electromagnetic force generated within a precision coil system. The resulting current is directly proportional to mass and digitally converted with high linearity and stability. Designed and assembled at Sartorius’ manufacturing facility in Beijing, this instrument complies with international metrological standards including OIML R76 and ISO/IEC 17025 requirements for calibration traceability. Its 120 g maximum capacity and 0.1 mg readability make it suitable for applications demanding sub-milligram resolution, such as pharmaceutical formulation, reference standard preparation, and quality control testing of active pharmaceutical ingredients (APIs).
Key Features
- Electromagnetic force compensation (EMFC) sensor architecture ensuring long-term stability and minimal drift over time
- Integrated draft shield with automatic door control and ergonomic sliding mechanism for rapid access and environmental isolation
- Internal calibration routine with motorized weights, supporting both automatic and user-initiated calibration at defined intervals
- Real-time level control system with visual and acoustic feedback, ensuring optimal weighing conditions before measurement initiation
- RS232 and USB interfaces compliant with ASTM E2656 and ISO 11352 data transmission protocols for seamless integration into LIMS and ELN platforms
- IP54-rated housing for resistance against dust ingress and incidental liquid splashes during routine operation
- GLP/GMP-compliant reporting with timestamped, operator-identified records—including calibration history, adjustment logs, and weighing events
Sample Compatibility & Compliance
The QUINTIX124-1CN accommodates standard analytical sample containers—including weighing boats, vials, crucibles, and filter papers—within its 120 g load limit. Its pan diameter (90 mm) and clearance height (230 mm) support compatibility with common labware used in pharmacopeial procedures (e.g., USP <41>, EP 2.1.3). The balance meets ISO 9001 quality management system requirements and supports audit-ready documentation per FDA 21 CFR Part 11 when paired with Sartorius LabX software. All factory calibrations are traceable to national metrology institutes (NMI) via DAkkS-accredited certificates, and the instrument is certified for use in environments adhering to ISO 14644-1 Class 8 cleanrooms.
Software & Data Management
When connected to Sartorius LabX™ software (optional), the QUINTIX124-1CN enables full electronic record integrity: role-based user authentication, electronic signatures, and immutable audit trails for all critical operations—including tare, calibration, and result export. LabX enforces workflow-driven SOP execution, automatically prompting users for calibration verification prior to batch weighing and enforcing data validation rules aligned with ICH Q7 and EU GMP Annex 11. Raw weighing data—including environmental parameters (temperature, humidity), internal diagnostics, and error codes—are stored in structured CSV or XML formats compatible with enterprise data archiving systems. Local data storage on the balance includes up to 1,000 weighing records with timestamps, operator IDs, and metadata tags.
Applications
- Quantitative analysis in QC laboratories performing assay validation, content uniformity testing, and dissolution sample preparation per USP <711>
- Weighing of reference standards and certified reference materials (CRMs) under ISO/IEC 17034 accreditation requirements
- Gravimetric preparation of calibration standards for HPLC, ICP-MS, and GC-MS instrumentation
- Material balance studies in pilot-scale API synthesis and formulation development
- Residual solvent determination using gravimetric loss-on-drying (LOD) methods compliant with ICH Q5C
- Teaching laboratories requiring NIST-traceable instruments for metrology education and uncertainty budgeting exercises
FAQ
What is the difference between readability and repeatability on the QUINTIX124-1CN?
Readability refers to the smallest increment displayed (0.1 mg); repeatability (1 mg) defines the standard deviation observed across ten consecutive weighings of the same test weight under identical conditions.
Is the QUINTIX124-1CN compliant with FDA 21 CFR Part 11?
Yes—when operated with LabX software and configured with appropriate user roles, electronic signatures, and audit trail settings, it satisfies electronic record and signature requirements.
Can the balance be calibrated externally using third-party weights?
Yes—the instrument supports external calibration using Class E2 or better stainless-steel weights, provided they are certified and traceable to national standards.
Does the Beijing-manufactured unit meet the same performance specifications as German-assembled models?
Yes—Sartorius maintains identical design, component sourcing, and final verification protocols across global production sites, validated per ISO 9001 and ISO/IEC 17025.
How often should internal calibration be performed?
Sartorius recommends initiating internal calibration after power-up, following significant ambient temperature shifts (>2 °C), and at user-defined intervals aligned with risk-based assessment per ISO/IEC 17025 clause 7.7.
