Sartorius BSA2202S and BSA2202S-CW Analytical Balance

Overview

The Sartorius BSA2202S and BSA2202S-CW are high-performance analytical balances engineered for precision mass measurement in regulated laboratory environments. Based on electromagnetic force compensation (EMFC) technology, these balances deliver stable, drift-resistant weighing results across a wide operational temperature range (10–30 °C) and humidity conditions (30–80% RH, non-condensing). With a maximum capacity of 2200 g and readability of 10 mg (0.01 g), the BSA2202S series bridges the functional gap between precision balances and entry-level analytical instruments—making it suitable for routine quality control, formulation verification, sample preparation, and inventory management tasks where sub-gram accuracy is required but microgram-level resolution is not essential. The dual-model configuration provides flexibility: the BSA2202S supports external calibration with certified weights, while the BSA2202S-CW integrates motorized internal calibration, enabling automated recalibration triggered by time intervals, temperature shifts (>1.5 °C), or user command—critical for maintaining traceability under ISO/IEC 17025 and FDA 21 CFR Part 11 compliance frameworks.

Key Features

• Electromagnetic force compensation sensor architecture ensures long-term stability and minimal drift over extended operation cycles.
• Large 180 × 180 mm stainless steel weighing pan accommodates voluminous samples, multi-vessel setups, or containers with high aspect ratios.
• Internal calibration (BSA2202S-CW) includes automatic temperature-triggered adjustment and scheduled recalibration logs compliant with audit trail requirements.
• RS232 and USB interfaces support direct data transfer to LIMS, ELN, or statistical process control (SPC) platforms without manual transcription.
• Integrated draft shield compatibility (optional accessory) enables operation in semi-controlled ambient conditions without compromising repeatability.
• Front-panel keypad with tactile feedback and intuitive icon-based navigation reduces operator training time and minimizes input errors.

Sample Compatibility & Compliance

The BSA2202S series accommodates solid, granular, and low-viscosity liquid samples within standard laboratory vessels—including beakers, weighing boats, and tared containers up to 200 mm in height. Its robust mechanical design meets IP42 ingress protection standards, providing resistance against dust and incidental splashes during daily use. From a regulatory standpoint, the balance supports full documentation of calibration events, user access logs, and measurement history—enabling alignment with Good Laboratory Practice (GLP), Good Manufacturing Practice (GMP), and pharmacopeial standards including USP “Weights and Balances” and EP 2.1.7. All firmware versions are validated per IQ/OQ protocols, and calibration certificates traceable to national metrology institutes (e.g., PTB, NIST) are available upon request.

Software & Data Management

Sartorius DataControl software (v3.x or later) is fully compatible with both models, enabling remote configuration, real-time data streaming, and customizable report generation—including PDF export with embedded digital signatures. Audit trails record every weight event, parameter change, calibration action, and user login with timestamp, operator ID, and reason-for-change fields—satisfying FDA 21 CFR Part 11 electronic record requirements. Data encryption (AES-128) and role-based access control (RBAC) ensure integrity and confidentiality across multi-user environments. Optional integration with LabWare LIMS or Thermo Fisher SampleManager is supported via HL7 or ASTM E1384 message mapping.

Applications

• Raw material receipt inspection and batch release testing in pharmaceutical and chemical manufacturing.
• Weighing of excipients and active pharmaceutical ingredients (APIs) during tablet formulation development.
• Preparation of standard solutions and buffer dilutions requiring ±0.5% accuracy at 2200 g load.
• Quality assurance checks for packaged goods, including net content verification per EU Directive 76/211/EEC.
• Educational laboratories conducting stoichiometric experiments, gravimetric analysis, or density determination.
• Environmental testing labs performing soil/sediment sample preparation prior to ICP-MS or AAS analysis.

FAQ

What is the difference between the BSA2202S and BSA2202S-CW models?

The BSA2202S requires external calibration using certified weights, whereas the BSA2202S-CW features an integrated motorized calibration mechanism that performs automatic internal calibration based on time, temperature deviation, or manual initiation.
Does this balance meet USP requirements for analytical weighing?

Yes—the BSA2202S series satisfies USP criteria for repeatability (≤10 mg), linearity (≤20 mg), and calibration frequency when operated within specified environmental limits and maintained per Sartorius service recommendations.
Can the balance be connected to a networked LIMS system?

Yes—via RS232 or USB-to-serial adapters, the balance transmits ASCII-formatted weight data compatible with ASTM E1384-compliant middleware for seamless LIMS ingestion.
Is GMP-compliant audit trail functionality built-in?

Audit trail recording is enabled by default in DataControl software; all critical events—including weight values, calibration actions, and user logins—are time-stamped, immutable, and exportable in CSV or PDF format.
What maintenance schedule is recommended for optimal performance?

Sartorius recommends quarterly preventive maintenance, annual sensor verification, and daily cleaning of the weighing chamber and pan using lint-free cloths and isopropyl alcohol—documented in accordance with ISO/IEC 17025 clause 6.4.10.
