Overview
The Metrohm Eco Semi-Automatic Titrator is an integrated, GLP-compliant liquid handling platform engineered for precision volumetric operations in routine analytical laboratories. Unlike traditional manual titration setups relying on glass burettes and volumetric flasks, the Eco combines a high-resolution digital burette, built-in magnetic stirrer, capacitive touch display, and embedded documentation system into a single compact unit. It operates on the principle of gravimetric and volumetric dispensing control—leveraging stepper-motor-driven piston technology to deliver reproducible liquid transfers with µL-level resolution. Designed for laboratories performing standardized titrations (e.g., acid-base, redox, precipitation), standard solution preparation, and sample dilution workflows, the Eco bridges the gap between fully automated titrators and basic manual systems—offering traceable, auditable, and operator-independent execution without requiring robotic integration or PC dependency.
Key Features
- Digital piston burette with adjustable dispensing rate via ergonomic hand controller, enabling real-time manual titration with visual and tactile feedback
- Integrated magnetic stirrer with speed control (0–1200 rpm) and automatic stirring activation during titration steps
- Capacitive 7-inch touchscreen interface supporting multilingual operation (English, German, French, Chinese, Spanish), intuitive method navigation, and on-device data review
- µL-level dispensing resolution (typical minimum increment: 1 µL) for fixed-volume additions, standard solution preparation, and reagent dosing
- GLP-compliant electronic record generation: timestamps, operator ID, method name, sample ID, raw volume data, and calculated results—all stored internally with optional USB export
- Onboard method library supporting up to 100 user-defined protocols, including pre-programmed calculation templates (e.g., molarity, normality, % w/v, ppm) and customizable report formats
- Automatic burette refilling and air-bubble detection algorithm to ensure consistent delivery accuracy across repeated cycles
Sample Compatibility & Compliance
The Eco accommodates aqueous and moderately polar organic solvents (e.g., ethanol, acetone, methanol) within standard chemical compatibility limits of PTFE, FEP, and borosilicate glass components. It supports sample vessels from 10 mL beakers to 250 mL Erlenmeyer flasks. All hardware and firmware conform to IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and EMC Directive 2014/30/EU. Data integrity features—including electronic signatures, audit trail logging, and immutable result storage—align with FDA 21 CFR Part 11 requirements when used in conjunction with Metrohm’s optional LabX Lite software for networked environments. The system meets ISO/IEC 17025 documentation expectations for accredited testing laboratories and supports GMP-relevant reporting through configurable PDF output templates.
Software & Data Management
All operational data—including titrant consumption, endpoint detection logic (e.g., first derivative, fixed potential), intermediate volumes, and final calculations—are retained in non-volatile memory. Internal storage capacity supports ≥10,000 titration records with full metadata. Export options include CSV (for LIMS integration), PDF (print-ready GMP reports), and XML (for structured data exchange). Optional connectivity via USB host port enables direct transfer to external drives or printers; Ethernet or Wi-Fi modules are not included but may be added via third-party serial-to-network adapters. Firmware updates are performed locally via USB stick, with version history and checksum verification ensuring traceability per ISO 9001 calibration management protocols.
Applications
- Routine quality control titrations in pharmaceutical, food & beverage, and chemical manufacturing (e.g., assay of active ingredients, chloride content, acidity value)
- Preparation of certified reference standards and working solutions under ISO Guide 34 and ISO/IEC 17025 traceability frameworks
- Method development and validation studies requiring precise volumetric spiking or dilution series generation
- Educational laboratories seeking a robust, low-maintenance platform for teaching volumetric analysis principles with full data traceability
- Environmental testing labs performing alkalinity, hardness, or COD-related titrations where regulatory documentation is mandatory
FAQ
Does the Eco Semi-Automatic Titrator require a computer to operate?
No—it functions as a standalone instrument with full method execution, calculation, and reporting capabilities independent of external PCs.
Can the Eco be calibrated according to ISO 8655 or ASTM E287?
Yes—volumetric accuracy verification follows ISO 8655-3 (piston burettes) using certified weights and Class A volumetric glassware; calibration certificates and SOP templates are available upon request.
Is the internal data storage encrypted or password-protected?
User access levels (Operator, Supervisor, Administrator) are enforced via PIN-based authentication; audit trails record all login events and parameter changes.
What maintenance is required for long-term reliability?
Routine maintenance includes monthly cleaning of the burette tip and stir bar, annual piston seal inspection, and biannual verification of dispensing accuracy using gravimetric checks.
Can custom calculation formulas be added beyond the built-in library?
Yes—users may define new equations using standard arithmetic operators and variables (e.g., mass, volume, molecular weight); formula syntax is validated prior to saving.
