Sartorius CPA2202S Precision Balance

Overview

The Sartorius CPA2202S Precision Balance is an ISO/GLP-compliant laboratory balance engineered for high-reproducibility mass measurement in routine analytical, quality control, and research environments. Utilizing Sartorius’ patented monolithic weighing sensor architecture, the CPA2202S delivers exceptional long-term stability and resistance to mechanical stress, thermal drift, and electromagnetic interference—critical attributes for consistent performance across multi-shift laboratory operations. With a 2200 g capacity and 0.01 g readability, it bridges the functional gap between analytical and top-loading balances, offering metrological rigor without compromising ergonomic efficiency. The balance operates under the isoCAL intelligent internal calibration system—a temperature-compensated, motor-driven self-calibration protocol that automatically initiates upon power-on, after defined time intervals, or following significant ambient temperature shifts (≥1.5 °C). This ensures continuous traceability to national standards without manual intervention, satisfying core requirements of ISO 17025-accredited laboratories and FDA 21 CFR Part 11–aligned workflows when paired with compliant data capture systems.

Key Features

• Monolithic electromagnetic force compensation (EMFC) sensor with integrated temperature compensation for minimal zero drift and superior long-term linearity.
• isoCAL fully automatic internal calibration and adjustment—no external weights required; supports scheduled, event-triggered, and manual activation via front-panel key.
• Backlit LCD display with 16 mm high digits, optimized for glare-free readability under varied ambient lighting conditions including UV-intensive fume hood environments.
• Robust stainless-steel weighing pan (190 × 204 mm) mounted on a rigid, vibration-damped base to minimize settling time and enhance repeatability (≤ ±0.01 g).
• RS-232C serial interface compliant with standard ASCII command protocols, enabling bidirectional communication with PCs, LIMS, ELN platforms, or Sartorius-certified printers (e.g., YDP03-0CE, YDP20-0CE).
• Built-in application functions: percentage weighing, parts counting, animal/dynamic weighing, net/gross accumulation, and SI/metric unit conversion—all accessible without firmware modification.

Sample Compatibility & Compliance

The CPA2202S accommodates a broad range of sample formats—including volumetric flasks, beakers, crucibles, and weigh boats—within its generous pan dimensions and 2200 g load limit. Its sealed housing meets IP42 ingress protection specifications, providing resistance to dust and incidental liquid splashes during standard lab handling. All firmware and hardware design adhere to European CE directives (EMC Directive 2014/30/EU, Low Voltage Directive 2014/35/EU) and comply with ISO 9001 manufacturing controls. For regulated environments, the balance supports GLP-compliant documentation through timestamped, operator-ID-tagged printouts (when used with YDP-series printers) or structured ASCII data export (CSV/TXT) compatible with validated PC-based data acquisition software. It fulfills essential metrological criteria referenced in USP , ASTM E898, and ISO 11352 for non-automatic weighing instruments.

Software & Data Management

Data integrity is maintained via configurable RS-232C output modes—including auto-print, manual trigger, and continuous streaming—each supporting optional operator ID entry and customizable header/footer fields. When interfaced with Sartorius LabX™ software (sold separately), the CPA2202S enables full audit trail generation, electronic signature enforcement, and automated report archiving aligned with 21 CFR Part 11 Subpart B requirements. Raw weight data is transmitted in ASCII format with embedded metadata (timestamp, stability flag, unit, mode), facilitating direct ingestion into statistical process control (SPC) tools or laboratory information management systems (LIMS). No proprietary drivers are required; standard Windows COM port configuration suffices for integration.

Applications

• Raw material verification and formulation batching in pharmaceutical and chemical manufacturing.
• Sample preparation for HPLC, GC, and ICP-MS analysis where precise mass-to-volume ratio consistency is critical.
• Calibration of volumetric glassware per ISO/IEC 17025 clause 6.4.3.
• Stability-indicating assays requiring repeated gravimetric monitoring over extended timeframes.
• Educational labs performing quantitative stoichiometry, density determination, and thermogravimetric pre-weighing protocols.
• Environmental testing labs conducting soil moisture content, filter residue, or suspended solids quantification.

FAQ

Does the CPA2202S support external calibration with traceable weights?
Yes—while isoCAL provides automated internal calibration, the balance accepts external calibration via certified Class M2 or better weights using the dedicated “External Cal” mode.
Is GLP-compliant printout possible without additional hardware?
No—GLP-compliant printed records require either the YDP03-0CE or YDP20-0CE thermal printer, which generates date/time-stamped, tamper-evident hard copies with operator identification fields.
Can the balance be integrated into a networked LIMS environment?
Yes—via RS-232C to USB or Ethernet serial server, the CPA2202S feeds ASCII-formatted weight data directly into LIMS middleware that supports serial device polling and structured data parsing.
What is the warm-up time required before first use?
Sartorius recommends a minimum 30-minute stabilization period at constant ambient temperature (±2 °C/hour variation) prior to initial calibration or critical measurements.
Is the monolithic sensor repairable in the field?
No—the monolithic sensor is a sealed, non-user-serviceable component; field service requires authorized Sartorius technical support and factory recalibration certification.
