Overview
The Shimadzu TXB Series represents a line of high-reliability, portable precision balances engineered for routine mass measurement in laboratory, quality control, and field-based applications. Built upon Shimadzu’s decades-long heritage in analytical instrumentation, the TXB Series employs electromagnetic force compensation (EMFC) technology — the industry-standard principle for high-accuracy weighing — ensuring stable, drift-resistant performance across varying ambient conditions. These balances are optimized for tasks requiring consistent readability at 0.01 g, 0.1 g, or 1 g resolution, depending on model configuration, and are particularly suited for applications where portability, rapid stabilization, and traceable calibration are critical. The series is designed to meet the functional expectations of ISO/IEC 17025-accredited laboratories and supports foundational compliance requirements for Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) workflows.
Key Features
- Electromagnetic force compensation (EMFC) sensor architecture delivering high reproducibility and long-term stability
- Fast stabilization time — typically 1–2 seconds — minimizing throughput bottlenecks in high-volume sample handling
- Robust aluminum alloy housing with integrated carrying handle and optional protective cover for transport and benchtop use
- Large, backlit LCD display with intuitive icon-driven interface; no menu nesting required for basic operation
- External calibration capability using certified weights (class E2 or better), supporting traceability to national metrology institutes
- Auto-zero tracking and automatic internal environmental compensation for temperature and air density fluctuations
- Multiple weighing units (g, oz, ct, lb, etc.) and built-in piece counting, percentage weighing, and checkweighing modes
- RS-232 interface standard; optional USB-to-serial adapter available for connectivity with LIMS or ERP systems
Sample Compatibility & Compliance
The TXB Series accommodates a broad range of sample types — from powders and granules to small components and packaged goods — thanks to its two standard pan configurations: 110 mm diameter (for models up to 620 g capacity) and 160 mm diameter (for higher-capacity models up to 6200 g). The stainless-steel weighing pan is corrosion-resistant and easily cleaned, suitable for non-hazardous, non-volatile samples in ambient lab environments. While not rated for hazardous area use (e.g., ATEX or IECEx), the TXB Series conforms to electromagnetic compatibility (EMC) standards per IEC 61326-1 and safety requirements under IEC 61010-1. Its design facilitates compliance with FDA 21 CFR Part 11 when paired with validated data capture software, and it supports audit trails via external logging tools compliant with GLP/GMP documentation protocols.
Software & Data Management
Data output follows NIST-traceable formatting conventions and is compatible with common laboratory informatics platforms. The RS-232 port transmits real-time weight values in ASCII format, including timestamps when enabled via host software. Shimadzu provides optional PC software (e.g., LabSolutions Lite) for basic data logging, statistical analysis (mean, SD, CV%), and report generation — all exportable to CSV or PDF. For regulated environments, third-party electronic lab notebook (ELN) or LIMS integrations can be configured to enforce user authentication, electronic signatures, and immutable audit trails aligned with 21 CFR Part 11 Annex 11 requirements. No onboard memory or internal storage is included — data integrity relies on external system validation, reinforcing procedural control over digital records.
Applications
- Raw material receipt inspection and batch release testing in pharmaceutical and chemical manufacturing
- Formulation and compounding support in R&D labs, including gravimetric preparation of standards and reference materials
- Quality assurance of packaged consumer goods (e.g., food, cosmetics, electronics) where net weight verification is mandated
- Educational laboratories requiring durable, entry-level precision balances for student instruction in metrology fundamentals
- Field-deployed environmental sampling operations requiring portable, battery-powered mass verification (with optional AC/DC adapter)
- Inventory management and component counting in electronics assembly and mechanical maintenance facilities
FAQ
What calibration standards are recommended for TXB Series balances?
Certified class E2 or better stainless-steel weights, traceable to NIST, PTB, or NMIJ, are recommended for external calibration. Calibration frequency should align with usage intensity and risk assessment per ISO/IEC 17025 Clause 6.5.
Is battery operation supported?
Yes — the TXB Series includes an integrated rechargeable battery (Li-ion) providing up to 8 hours of continuous operation; battery status is displayed on-screen and charging occurs via included AC adapter.
Can the TXB Series be used in a fume hood?
It may be installed in a low-turbulence fume hood if airflow across the pan is minimized (<0.2 m/s); however, draft shields are not included and must be added separately for volatile or low-density samples.
Does the balance support auto-calibration?
No — the TXB Series requires manual external calibration; it does not include internal motorized calibration weights or temperature-triggered recalibration routines.
What is the warranty coverage for TXB instruments?
Shimadzu offers a standard 2-year limited warranty covering parts and labor for defects in materials and workmanship under normal laboratory use conditions.
