Sartorius TX-110SA Balance Data Printer with GLP/GMP-Compliant Reporting

Overview

The Sartorius TX-110SA Balance Data Printer is a dedicated, standalone reporting peripheral engineered for high-integrity data capture in regulated laboratory and manufacturing environments. Designed to interface seamlessly with Sartorius analytical and precision balances—including S, Q, P, CPA, and BS series models—it operates as an independent data acquisition and documentation module that augments native balance functionality without requiring proprietary software or host PC dependency. Its core architecture implements an 8-pin impact dot-matrix printing mechanism using standard plain paper and Epson ERC-09 or ERC-22 ribbons—ensuring archival-grade permanence, chemical resistance, and long-term legibility required under Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) frameworks. Unlike thermal printers subject to fading or environmental degradation, the TX-110SA produces tamper-evident, audit-ready hard copies compliant with ISO/IEC 17025, USP <1058>, and FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed with appropriate access controls.

Key Features

• Two-tier user permission system (Operator + Administrator) enabling role-based control over time/date settings, report templates, calibration parameters, and print configuration—fully aligned with FDA 21 CFR Part 11 audit trail expectations.
• Configurable header/footer sections supporting up to 12 customizable fields: instrument ID, serial number, sample name/batch ID, timestamp (date/time), sequence number, operator signature line, and custom annotations—each field independently enabled or suppressed per report type.
• Integrated statistical engine capable of processing up to 300 sequential weighing entries with 64-bit double-precision arithmetic, delivering mean, standard deviation, coefficient of variation, sum, min/max, and delta values—without rounding artifacts or floating-point truncation.
• Dedicated pipette and volumetric flask calibration mode compliant with JJG 646–2006 national metrological verification regulation; automatically applies temperature-dependent K_t correction to convert measured mass into volume at 20 °C reference temperature.
• OLED display (128 × 64 pixels) with bilingual (English/Chinese) UI support, real-time preview of pending print jobs, and on-device navigation for parameter adjustment without external software.
• Multi-mode reporting: Weighing (tare/net/gross), Statistics, Formulation, Accumulation, Moisture Loss (loss-on-drying), and Subtraction modes—all generating traceable, timestamped, and sequentially numbered outputs.

Sample Compatibility & Compliance

The TX-110SA supports bidirectional communication with over 200 balance models across leading manufacturers—including Sartorius, Mettler Toledo (ME, AG, ZB, AL, ICS), Shimadzu (TX, AP, ATX, AUW), Ohaus (Scout), A&D, Shimadzu, and INTEK (formerly Sartorius Midrics). It also interfaces with select electrochemical instruments (e.g., Metrohm and Mettler Toledo pH meters, potentiometric titrators, Karl Fischer coulometers), dissolution testers, hardness testers, UV-Vis spectrophotometers, and calipers via configurable ASCII protocol mapping. All printed reports include embedded metadata required for regulatory submissions: instrument identity, environmental conditions (if transmitted), operator ID, calibration status flags, and digital signature placeholders. Raw data export to USB storage devices generates CSV-formatted files compatible with Excel, LIMS, and ELN systems—preserving original timestamps and sequence integrity.

Software & Data Management

No host computer or driver installation is required—the TX-110SA operates autonomously upon connection to the balance’s serial or USB port. Configuration is performed locally via front-panel keys and OLED menu navigation. Print templates are stored in non-volatile memory and persist through power cycles. Audit trails—including all parameter changes, user logins, and print job initiations—are retained internally with date/time stamps and user-level attribution. Optional firmware updates are delivered via USB stick, maintaining version traceability and change control documentation per ISO 9001 Clause 7.5.3. Data export files include checksums and row-level timestamps to support ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

This printer serves critical functions in QC/QA laboratories performing routine weight-based assays, including but not limited to: raw material receipt inspection, formulation batch release testing, reference standard weighing, volumetric equipment verification (pipettes, burettes, flasks), moisture content determination by gravimetric loss-on-drying, and compendial method compliance (USP <41>, EP 2.1.6). In pharmaceutical manufacturing, it fulfills Annex 11 and EU GMP Chapter 4 requirements for data integrity during balance qualification (IQ/OQ/PQ), periodic verification, and routine use monitoring. Its deterministic output eliminates transcription errors, reduces manual data entry burden, and provides immutable evidence for internal audits and regulatory inspections.

FAQ

Does the TX-110SA require a PC or dedicated software to operate?
No—it functions as a standalone peripheral with no PC dependency. All configuration and operation occur via the built-in OLED interface.
Is thermal paper required?
No—only standard 57 mm plain paper is used; thermal sensitivity is not supported or necessary.
Can it generate FDA 21 CFR Part 11–compliant reports?
Yes—when deployed with administrator-controlled access, timestamped audit logs, and signed report footers, it satisfies electronic record and signature requirements for regulated environments.
What calibration standards does the pipette mode follow?
It implements JJG 646–2006 methodology, including automatic K_t correction and volumetric equivalence calculations referenced to 20 °C.
How is data integrity ensured during USB export?
Exported CSV files retain original sequence numbers, timestamps, and measurement units; filenames include device ID and export date to prevent ambiguity or misattribution.
