Sartorius BSA124-1CCN Analytical Balance (0.1 mg readability, 120 g capacity)

Overview

The Sartorius BSA124-1CCN is a high-precision analytical balance engineered for laboratories requiring trace-level mass measurement with metrological integrity and operational robustness. Designed in accordance with international weighing standards—including OIML R76, ISO 9001, and ISO/IEC 17025—the BSA124-1CCN delivers 0.1 mg readability across its full 120 g weighing range. Its electromagnetic force compensation (EMFC) transducer ensures long-term stability, minimal drift, and high reproducibility under variable ambient conditions. The balance operates within a controlled temperature range of +10 °C to +30 °C, with sensitivity drift limited to ≤1.5 ppm/K—critical for environments lacking climate stabilization. With a typical stabilization time of ≤2.0 seconds and linearity deviation capped at ≤0.2 mg, the instrument supports rapid, high-throughput workflows without compromising accuracy. Its compact 90 mm diameter stainless-steel weighing pan accommodates standard labware while maintaining optimal load distribution and mechanical isolation.

Key Features

• Graphical color touchscreen interface with intuitive icon-based navigation and real-time weight trend visualization
• 11 built-in weighing applications: Standard weighing, sample addition, piece counting, percentage weighing, formulation (net/gross/tare), summation, animal weighing, free-factor calculation, density determination, under-hook weighing, statistics, and unit conversion
• External calibration capability with automatic calibration prompt logic and user-defined calibration intervals
• Four-stage adjustable anti-vibration feet—mechanically tuned to dampen floor-borne disturbances from HVAC systems, foot traffic, or nearby equipment
• Dual communication interfaces: High-speed USB-C for direct data export to PCs or flash drives, and legacy RS232 for integration with LIMS or legacy lab software
• GLP/GMP-compliant reporting: Auto-generated printouts include date/time stamp, operator ID (via optional keypad or RFID), balance ID, calibration status, environmental conditions (if external sensors connected), and traceable audit trail metadata

Sample Compatibility & Compliance

The BSA124-1CCN is compatible with a broad spectrum of sample types—from microgram-scale pharmaceutical actives and reference standards to viscous liquids, powders, and small solid components used in materials science or quality control labs. Its draft shield (sold separately, compatible with Sartorius BSA-series shields) enables stable measurements of low-mass, high-surface-area samples. The balance meets essential regulatory expectations for analytical instrumentation: it supports 21 CFR Part 11–compliant data integrity when paired with Sartorius LabX software (optional); provides configurable user access levels; maintains tamper-evident electronic records; and logs all critical events—including zeroing, taring, calibration, and parameter changes—with timestamps and operator attribution. While the base unit does not include internal motorized calibration, its external calibration architecture aligns with ISO/IEC 17025 clause 6.4.8 on verification of measurement equipment performance.

Software & Data Management

Data handling is optimized for both standalone and networked environments. Via USB-C, users can export CSV-formatted datasets—including raw weight values, timestamps, application mode, and metadata—to external storage or laboratory information management systems (LIMS). When integrated with Sartorius LabX software (v3.5+), the BSA124-1CCN supports fully automated workflows: method-driven weighing protocols, electronic signature capture, real-time statistical process control (SPC) charting, and centralized instrument monitoring across multi-site deployments. All exported files retain embedded balance identification and calibration history, fulfilling traceability requirements under ISO 17025 and EU Annex 11. Audit trails are stored locally and exportable in encrypted PDF format, ensuring compliance during FDA, EMA, or notified body inspections.

Applications

This balance serves core functions in regulated and research-intensive settings: quantitative assay preparation in QC labs (e.g., USP precision testing), gravimetric standard solution preparation per ASTM E200, active pharmaceutical ingredient (API) dispensing in GMP manufacturing, catalyst loading in catalysis studies, residual solvent analysis sample weighing, and micro-sample characterization in nanomaterials labs. Its repeatability of ≤0.1 mg at full load makes it suitable for pharmacopeial uniformity of dosage units testing (USP ) and dissolution sample preparation where mass uncertainty must remain below 0.1%. The density determination function—when used with a density kit—supports solid and liquid density measurements per ISO 1183 and ASTM D792.

FAQ

Is the BSA124-1CCN compliant with 21 CFR Part 11?
Yes—when operated with Sartorius LabX software and appropriate user access controls, electronic signatures, and audit trail configuration.
Does it support internal motorized calibration?
No—the BSA124-1CCN uses external calibration; for internal calibration, consider the BSA124I-1CCN variant.
Can the balance be integrated into a LIMS environment?
Yes—via RS232 or USB-C using ASCII protocol or LabX middleware; Sartorius provides documented interface specifications and driver libraries.
What environmental conditions affect its performance?
Ambient temperature fluctuations >1 °C/hour or drafts exceeding 0.2 m/s may impact stability; installation on a vibration-isolated bench is recommended.
Is GLP printout functionality built-in?
Yes—direct thermal printing (with optional Sartorius PR 50 printer) includes balance ID, calibration due date, operator ID field, and timestamped weight records.
