Sartorius ME614S Analytical Balance

Overview

The Sartorius ME614S Analytical Balance is a high-precision laboratory instrument engineered for demanding quantitative analysis in regulated and research-intensive environments. Based on electromagnetic force compensation (EMFC) technology, it delivers trace-level mass measurement stability and repeatability under variable ambient conditions. With a 610 g capacity and 0.1 mg readability, the ME614S meets the stringent requirements of pharmacopeial testing (USP , ), method validation, reference standard preparation, and quality control workflows. Its core architecture integrates thermal mass stabilization, real-time drift compensation, and adaptive environmental monitoring — ensuring consistent performance across temperature fluctuations and air currents typical in open-lab or multi-user settings.

Key Features

• Motorized three-sided draft shield with self-learning drive mechanism — enables programmable, repeatable opening/closing sequences via touch key or software trigger.
• Integrated anti-static system featuring dual-polarity ionizer and one-touch charge neutralization — eliminates electrostatic interference from glassware, plastic vials, or powder samples without manual intervention.
• isoCAL automatic internal calibration and adjustment — fully temperature-compensated, triggered manually or scheduled, compliant with ISO 9001 and GLP documentation requirements.
• SQmin function — calculates and displays the minimum sample weight per USP , dynamically updated based on current repeatability and readability; supports audit-ready reporting.
• Graphic LCD with white LED backlight and intuitive icon-based navigation — optimized for gloved operation and low-contrast lighting conditions.
• RS232C bidirectional interface — supports direct connection to Sartorius printers (e.g., YDP10/20), LIMS, or PC-based data acquisition systems; configurable print formats meet 21 CFR Part 11 requirements when paired with compliant software.

Sample Compatibility & Compliance

The ME614S accommodates standard Ø 90 mm stainless-steel weighing pans and is compatible with a broad range of sample containers — including volumetric flasks, crucibles, filter papers, and low-profile pipette calibration vessels. Its motorized draft shield configuration minimizes turbulence during rapid access, making it suitable for sequential weighing of multiple small-volume samples. The balance conforms to ISO/IEC 17025 calibration traceability standards and supports full GLP/GMP compliance through audit trails, user access levels, electronic signatures (when integrated with Sartorius LabX software), and secure data export. All firmware and calibration records are timestamped and tamper-evident.

Software & Data Management

While the ME614S operates as a standalone instrument with embedded application software (pipette calibration, percentage weighing, density determination, net/gross/tare, statistical evaluation), it is fully interoperable with Sartorius LabX™ software. LabX provides centralized method management, automated report generation, electronic signature support, and full 21 CFR Part 11 compliance — including role-based permissions, audit trail logging, and data integrity verification. Raw weighing data can be exported in CSV, XML, or PDF formats, preserving metadata such as operator ID, timestamp, environmental conditions, and calibration status.

Applications

• Pharmaceutical QC/QA: USP-compliant assay preparation, reference standard weighing, excipient blending, and content uniformity testing.
• Chemical R&D: Precise reagent dispensing, stoichiometric reaction setup, and catalyst loading verification.
• Environmental labs: Filter weighing for particulate matter (PM2.5/PM10) analysis and gravimetric water content determination.
• Clinical diagnostics: Calibration of automated liquid handlers and verification of critical reagent concentrations.
• Academic research: Teaching laboratories requiring robust, intuitive operation and long-term measurement stability across student shifts.

FAQ

What does “isoCAL” mean and how does it differ from standard internal calibration?
isoCAL is Sartorius’ proprietary temperature-compensated internal calibration system. Unlike basic internal calibration, isoCAL monitors ambient temperature in real time and adjusts calibration parameters accordingly — ensuring accuracy across ±5 °C operational ranges without manual recalibration.
Is the ME614S suitable for pipette calibration according to ISO 8655?
Yes — its 8-second stabilization time, 0.1 mg readability, and optional short-height draft shield (available on ME235P-SD variant) meet ISO 8655-6 gravimetric verification requirements for Class A and AS pipettes.
Can the balance store calibration history and generate compliance reports?
Yes — all calibration events (date, time, operator, deviation values) are stored internally and exportable via RS232. When connected to LabX, full electronic audit trails with digital signatures are generated per 21 CFR Part 11.
Does the anti-static function require external accessories or consumables?
No — the integrated bipolar ionizer operates autonomously; no replaceable emitters, wires, or grounding cables are needed. Neutralization is initiated with a single front-panel keypress.
What warranty coverage applies to the ME614S in international markets?
The instrument includes a standard 3-year manufacturer’s warranty covering parts, labor, and firmware updates. Extended service plans up to 5 years are available globally through authorized Sartorius service partners.
