Sartorius BSA2202S Precision Balance

Overview

The Sartorius BSA2202S Precision Balance is an industrial-grade weighing instrument engineered for high-throughput laboratories, quality control environments, and production facilities requiring reliable mass determination in the 2200 g range with 10 mg readability. Utilizing a robust monolithic dual-lever electromagnetic force compensation sensor architecture, the BSA2202S delivers stable, drift-resistant measurements under variable ambient conditions. Its measurement principle relies on precise null-balance detection—where the gravitational force exerted by the sample is counteracted by a proportional electromagnetic restoring force, digitally transduced into mass value with traceable linearity. Designed for routine precision weighing—not analytical-level metrology—the balance meets ISO/IEC 17025 preconditions for calibration verification and supports audit-ready workflows in regulated industries including pharmaceutical manufacturing, food safety testing, and polymer formulation.

Key Features

• Monolithic dual-lever electromagnetic force restoration sensor for enhanced mechanical stability and long-term repeatability
• Anti-static coated five-sided glass draft shield minimizing electrostatic interference and enabling unobstructed sample visibility
• Automatic internal calibration (BSA2202S-CW variant) with built-in reference weights; external calibration supported via standard weights (BSA2202S)
• Dynamic temperature compensation algorithm actively corrects thermal drift across operating ranges (10–40 °C)
• Integrated 40 MHz microprocessor (MC1) enabling sub-second stabilization (≤1.1 s typical) and real-time signal filtering
• Front-mounted bubble level and adjustable feet ensure rapid, repeatable leveling without tools
• RS232 serial interface compliant with GLP data integrity requirements—including time-stamped weight records, operator ID fields, and device identification
• Dual tare keys (left/right placement) accommodate ergonomic preferences and glove-compatible operation
• Below-balance hook for density determination, magnetic susceptibility assessment, or large-volume container weighing

Sample Compatibility & Compliance

The BSA2202S accommodates samples up to 2200 g on its 180 × 180 mm stainless-steel weighing pan, optimized for volumetric containers, bulk powders, packaged goods, and intermediate-sized laboratory vessels. Its draft shield design complies with ISO 9001 environmental control guidelines for non-critical weighing tasks and supports USP general chapter allowances for precision balances used in non-quantitative assay preparation. While not certified for Class I or II analytical applications per OIML R76, the instrument satisfies ASTM E898-22 criteria for “precision laboratory balances” when operated within specified environmental tolerances (humidity ≤80% RH non-condensing, vibration isolation recommended). All firmware and hardware configurations adhere to Sartorius’ internal GLP/GMP design controls, ensuring full traceability of calibration events, maintenance logs, and user-access history where enabled via connected software.

Software & Data Management

Data export follows standardized ASCII protocol over RS232, supporting direct integration with LIMS, ELN, and MES platforms. Each transmitted record includes: timestamp (YYYY-MM-DD HH:MM:SS), net weight value (g), unit identifier, stability flag (“STABLE” or “UNSTABLE”), operator code (if entered), and balance serial number. Optional Sartorius LabX Lite software provides basic data aggregation, statistical reporting (mean, SD, CV%), and PDF certificate generation compliant with FDA 21 CFR Part 11 when deployed with user authentication and electronic signature modules. Audit trails capture all parameter changes—including calibration date/time, zero adjustment, and unit selection—with immutable timestamps stored in non-volatile memory.

Applications

• Raw material receipt inspection in chemical and pharmaceutical supply chains
• Batch formulation and blending verification for excipients and active ingredients
• Quality assurance testing of packaged consumer goods (e.g., net content compliance per EU Directive 76/211/EEC)
• Moisture content analysis support via gravimetric loss-on-drying protocols
• Industrial density determination using sinker method with optional accessories
• Inventory management and warehouse reconciliation workflows
• Educational laboratories requiring durable, serviceable precision instrumentation

FAQ

What is the difference between BSA2202S and BSA2202S-CW?
The “CW” suffix denotes internal calibration capability with a motorized built-in weight; the standard BSA2202S requires manual external calibration.
Does this balance meet ISO/IEC 17025 requirements for accredited labs?
It supports essential metrological functions required for uncertainty budgeting (repeatability, linearity, eccentricity), but formal accreditation depends on site-specific validation, environmental monitoring, and documented traceability to national standards.
Can the balance be connected to a networked system?
Yes—via RS232-to-Ethernet gateway or USB-serial adapter; native Ethernet or Wi-Fi are not supported on this model.
Is the draft shield removable for cleaning?
Yes—the five-sided glass shield is tool-free detachable and compatible with isopropanol-based disinfectants per Sartorius cleaning guidelines.
What maintenance intervals are recommended?
Daily verification with calibrated check weight, quarterly performance verification, and annual preventive maintenance by authorized Sartorius service personnel.
