Sartorius CPA6202P Precision Balance

Overview

The Sartorius CPA6202P Precision Balance is an ISO/GLP-compliant laboratory balance engineered for high-reliability routine weighing tasks in quality control, research, and production environments. Built upon Sartorius’ monolithic weighing sensor architecture—patented for mechanical stability and thermal drift resistance—the CPA6202P delivers consistent accuracy across its full 6200 g capacity with a readability of 0.05 g. Its measurement principle relies on electromagnetic force compensation (EMFC), where load-induced displacement is counterbalanced by a precisely regulated current through a coil within a permanent magnetic field; the resulting current magnitude is linearly proportional to mass and digitally resolved to ensure traceable, reproducible results. Designed for continuous operation in regulated laboratories, the CPA6202P meets foundational metrological requirements for repeatability (≤ ±0.03 g) and linearity (≤ ±0.05 g), supporting compliance with ISO 17025, USP , and pharmacopeial general chapters requiring documented weighing integrity.

Key Features

• Integrated isoCAL automatic internal calibration and adjustment system—motor-driven, temperature-compensated, and triggered manually or on schedule to maintain long-term accuracy without external weights.
• Backlit LCD display with 16 mm high digits ensures legibility under variable ambient lighting conditions, minimizing operator error during high-throughput workflows.
• Robust stainless-steel pan (190 × 204 mm) and reinforced housing optimized for durability in multi-user lab settings with frequent handling and cleaning cycles.
• RS-232C serial interface enables bidirectional communication with PCs, LIMS, or peripheral devices—including optional Sartorius YDP20-0CE thermal printer—for automated data capture and audit-ready output.
• Built-in application functions: percentage weighing, net weight summation, animal (dynamic) weighing, unit conversion (g, oz, ct, etc.), and piece counting—each configurable without third-party software.
• GLP-compliant data logging: time-stamped weight records include date, time, operator ID (if enabled), balance ID, and calibration status—exportable via RS-232 for integration into electronic lab notebooks or QA documentation systems.

Sample Compatibility & Compliance

The CPA6202P accommodates a broad range of sample types—from powders and granules to packaged reference standards and small containers—within its large pan geometry and low-profile design. Its draft shield compatibility (sold separately) supports volatile or hygroscopic samples requiring environmental isolation. All firmware and hardware configurations adhere to ISO 9001 manufacturing controls and undergo factory verification per OIML R76-1 and EN 45501. For regulated environments, the balance supports 21 CFR Part 11 readiness when paired with validated Sartorius LabX software (not included), enabling electronic signatures, role-based access control, and full audit trail generation for calibration, weighing, and maintenance events.

Software & Data Management

While the CPA6202P operates autonomously via front-panel controls, its RS-232C interface provides native compatibility with Sartorius’ LabX Lite (free) and full LabX software suites. LabX Lite enables basic data export, template-driven report generation, and printer configuration. Full LabX adds centralized instrument management, SOP-guided workflows, statistical process control (SPC) charting, and seamless integration with ERP or MES platforms. All data exports are ASCII- or CSV-formatted, timestamped, and include metadata required for GLP/GMP audits—including calibration history, environmental logs (if external sensors are connected), and user authentication traces.

Applications

• Raw material and finished product verification in pharmaceutical and nutraceutical manufacturing (per USP ).
• Formulation preparation and batch record documentation in R&D labs requiring ISO 17025 traceability.
• Inventory management and component counting in electronics and precision engineering facilities.
• Teaching laboratories requiring robust, intuitive instrumentation for metrology fundamentals instruction.
• Environmental testing labs performing soil, sediment, or filter-weight analysis per EPA Method 1669 or ASTM D2234.
• Food and beverage QC for portion control validation, additive dosing, and label claim verification.

FAQ

Does the CPA6202P support external calibration with certified weights?
Yes—while isoCAL provides fully automated internal calibration, the balance also accepts external calibration via standard Class M1 or better weights using the dedicated external calibration mode.
Is the RS-232C interface compatible with modern Windows/macOS systems?
Yes—when used with a USB-to-RS-232 adapter (e.g., FTDI chipset), the interface supports direct connection to contemporary PCs running LabX Lite or third-party data acquisition software.
Can multiple CPA6202P units be managed centrally?
Yes—LabX software enables concurrent monitoring, remote calibration scheduling, firmware updates, and consolidated reporting across heterogeneous Sartorius device fleets.
What documentation is provided for IQ/OQ validation?
Sartorius supplies a comprehensive Validation Support Package (VSP) including URS templates, test protocols, and blank execution records aligned with GAMP5 guidelines.
Is the display readable in low-light cleanroom environments?
Yes—the high-contrast, backlit LCD maintains optimal visibility at illumination levels as low as 50 lux, meeting ISO 14644-1 cleanroom operational requirements.
