Overview
The Sartorius Secura225D-1CN is a high-performance dual-range analytical balance engineered for precision mass measurement in regulated and research-intensive laboratory environments. Utilizing electromagnetic force compensation (EMFC) technology, it delivers traceable, stable, and reproducible results across two distinct weighing ranges—200 g at 0.01 mg readability and 500 g at 0.1 mg readability—enabling seamless transition between ultra-micro and standard analytical tasks without instrument changeover. Its robust monolithic sensor architecture minimizes thermal drift and mechanical hysteresis, while the integrated draft shield with optimized airflow dynamics ensures measurement integrity even under variable ambient conditions. Designed to meet the metrological requirements of ISO/IEC 17025-accredited laboratories, the Secura225D-1CN supports GLP/GMP workflows through full audit trail capability, user access control, and hardware-level data integrity safeguards.
Key Features
- Intuitive 4.3-inch color touchscreen interface with context-sensitive guidance—no manual required for routine operation
- Dual-range weighing mode: 0.01 mg resolution up to 200 g; 0.1 mg resolution up to 500 g—optimized for both high-sensitivity and high-capacity applications
- isoCAL automatic internal calibration and adjustment system, triggered by time intervals (configurable from 1–24 h) or temperature fluctuations ≥1.5 K—ensuring continuous compliance with ASTM E899 and USP <41>
- Integrated PC connectivity via USB host/device and Ethernet ports—supports direct data export to LIMS, ELN, or spreadsheet applications without third-party software
- Optional Sartorius YDP30 or YDP40 laboratory printer with one-touch print functionality and customizable report templates (weight, date/time, operator ID, stability indicator)
- Advanced draft shield with removable side doors and front sliding window—designed for rapid sample access while maintaining Class I or II environmental isolation per ISO 17025 Annex A.3
Sample Compatibility & Compliance
The Secura225D-1CN accommodates a broad spectrum of sample types—from volatile solvents and hygroscopic powders to dense metal alloys and fragile biological specimens—thanks to its adjustable leveling feet, anti-static ionizer compatibility, and optional anti-vibration table mounting kit. All firmware and hardware configurations comply with regulatory frameworks governing analytical instrumentation, including FDA 21 CFR Part 11 (electronic records/signatures), EU Annex 11 (computerized systems), and ISO 9001:2015 quality management requirements. Each unit ships with a factory-issued calibration certificate traceable to national standards (NIM, China) and includes documentation supporting IQ/OQ/PQ validation protocols.
Software & Data Management
Sartorius LabX™ software (optional) provides full remote control, method-driven workflows, real-time statistical analysis (RSD, trend charts, tolerance checking), and automated report generation compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Local device memory retains ≥10,000 weight records with timestamps, operator IDs, and environmental metadata (temperature, humidity if external sensors connected). Data export formats include CSV, PDF, XML, and direct SQL database push—fully compatible with enterprise-grade laboratory informatics infrastructure.
Applications
- Quantitative gravimetric preparation of reference standards and calibration solutions (USP <1251>, EP 2.1.17)
- Residual solvent analysis by loss-on-drying (LOD) and thermogravimetric methods (ASTM E1868)
- Pharmaceutical content uniformity testing per USP <905> and ICH Q5C
- Material density determination using Archimedean principle with Sartorius density kits
- Micro-reaction stoichiometry in synthetic chemistry labs requiring sub-100 µg mass resolution
- Quality control of catalysts, nanomaterials, and battery electrode coatings where mass variation <0.02 mg impacts performance metrics
FAQ
What does “dual-range” mean for the Secura225D-1CN?
It operates in two independent weighing modes: high-resolution (0.01 mg) up to 200 g, and high-capacity (0.1 mg) up to 500 g—switched automatically or manually based on load detection.
Is isoCAL compliant with ISO 17025 calibration requirements?
Yes—isoCAL satisfies clause 6.5.2 of ISO/IEC 17025:2017 when configured with documented time/temperature triggers and logged calibration events.
Can the balance be integrated into a validated LIMS environment?
Absolutely—the built-in Ethernet port supports TLS 1.2-encrypted communication, digital signature verification, and electronic audit trails meeting 21 CFR Part 11 Subpart B criteria.
Does the Secura225D-1CN support dynamic weighing or animal weighing modes?
No—this model is optimized exclusively for static analytical weighing; dynamic or motion-tolerant functions are available only on Sartorius Entris or Cubis® II series balances.
What is the typical warm-up time before first use?
Recommended stabilization period is 30 minutes after power-on under ambient lab conditions (20–25°C, <60% RH); isoCAL activation during warm-up ensures optimal sensor conditioning.
