Overview
The Shimadzu AT-R Series Advanced Analytical Balance (model ATX224R) is a high-precision mass measurement instrument engineered for laboratories requiring trace-level accuracy, regulatory compliance, and operational robustness in dynamic environmental conditions. Utilizing electromagnetic force restoration (EMFR) technology, the ATX224R delivers stable, drift-compensated weighing performance with a readability of 0.1 mg across its nominal capacity of 220 g (extended overload capacity up to 320 g). Its core architecture integrates Shimadzu’s proprietary Proactive Self-Calibration (PSC) system, which continuously monitors internal temperature gradients and triggers recalibration alerts when thermal deviations exceed predefined thresholds—ensuring metrological integrity without manual intervention. Designed for ISO/IEC 17025-accredited labs and GLP/GMP environments, the balance meets fundamental requirements for traceable mass measurement under ASTM E898, USP , and OIML R76 guidelines.
Key Features
- Five-step dynamic response adjustment (R/S modes): Optimizes weighing behavior for either rapid sample response (e.g., volatile liquids or fine powders) or enhanced stability under mechanical vibration or air currents.
- Dual calibration capability: Internal calibration via built-in reference weights and external calibration using certified Class E2 or better weights—fully traceable to NIST or BIPM standards.
- Integrated dual communication interfaces: Standard USB (virtual COM port) and RS-232C ports enable seamless integration with LIMS, ERP, or automated manufacturing systems (e.g., PLC-controlled batching stations), eliminating transcription errors and supporting 21 CFR Part 11–compliant data capture when paired with validated software.
- Electrostatic mitigation support: Compatible with the optional STABLO™-AP active ionizing discharger and Shimadzu Smart Stand Holder—reducing surface charge accumulation on glassware, plastic containers, and powdered samples to maintain repeatability at ≤0.1 mg level.
- Intelligent draft shield compatibility: Designed for use with Shimadzu’s motorized or manual double-door draft enclosures (sold separately), minimizing convective interference during microgram-level determinations.
Sample Compatibility & Compliance
The ATX224R accommodates standard analytical vessels—including volumetric flasks (up to 1 L), crucibles, weighing boats, and custom sample holders—within its 190 mm pan diameter. Its low-profile weighing chamber allows unobstructed access for pipetting or solvent addition during tare-and-add workflows. All firmware and hardware configurations adhere to electromagnetic compatibility (EMC) Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. The balance supports audit trail generation (when used with Shimadzu LabSolutions Balance Module or third-party compliant middleware), fulfilling documentation requirements for FDA inspections and ISO 9001 quality management audits.
Software & Data Management
Raw weight values are transmitted in ASCII format via configurable baud rates (RS-232C) or CDC-class USB protocol. Shimadzu provides free PC utility software (Balance Manager) for real-time data logging, statistical analysis (mean, SD, CV%), and CSV export. For regulated environments, the ATX224R is compatible with validated electronic lab notebook (ELN) platforms and can be configured to generate timestamped, user-ID–authenticated records with digital signatures—meeting ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).
Applications
- Quantitative preparation of reference standards and calibration solutions in pharmaceutical QC labs (USP ).
- Weighing of catalysts, APIs, and excipients in formulation development where batch-to-batch consistency demands ≤0.05% RSD.
- Gravimetric moisture analysis using loss-on-drying protocols (ASTM D2298, ISO 15512).
- Preparation of ICP-MS and HPLC mobile phase stock solutions requiring sub-milligram precision.
- Material balance verification in pilot-scale chemical synthesis and reaction calorimetry studies.
FAQ
Does the ATX224R support automatic internal calibration during operation?
Yes—the PSC system initiates internal calibration automatically upon detecting temperature shifts exceeding ±1.5°C from the last calibration baseline, provided the balance remains powered and undisturbed.
Can the balance be integrated into a networked laboratory environment?
While the ATX224R lacks native Ethernet or Wi-Fi, it supports TCP/IP bridging via USB-to-Ethernet adapters and is fully compatible with Shimadzu’s LabSolutions Connect gateway for centralized device monitoring and remote diagnostics.
Is external calibration required after internal calibration?
Internal calibration verifies sensor linearity and zero point; however, periodic external calibration using traceable standards remains mandatory per ISO/IEC 17025 Clause 6.5 and internal SOPs governing measurement uncertainty budgets.
What is the warm-up time required for optimal performance?
Shimadzu recommends a minimum 30-minute stabilization period after power-on under ambient temperature control (20 ±2°C, RH <60%) before initiating critical measurements.
How does the Smart Stand Holder improve electrostatic dissipation?
The stand positions samples at an optimized distance from the STABLO™-AP emitter nozzle while grounding the holder body—enhancing ion delivery efficiency and reducing residual charge by >90% compared to free-standing placement.
