METTLER TOLEDO ErgoClips Weighing Accessories Kit

Overview

The METTLER TOLEDO ErgoClips Weighing Accessories Kit is an engineered solution for high-precision, contamination-controlled sample handling on analytical and semi-micro balances. Designed in accordance with the principles of Good Weighing Practice™ (GWP®), this modular system eliminates manual transfer steps by enabling direct dosing into tared, balance-integrated containers—thereby reducing static charge interference, minimizing sample loss, and improving repeatability. ErgoClips operate within the controlled environment of METTLER TOLEDO’s MinWeigh Doors and compatible draft shields, ensuring stable weighing conditions under ISO 17025-conducive laboratory settings. The kit does not constitute a standalone instrument but functions as a certified accessory ecosystem, validated for traceable mass measurement workflows in regulated environments including pharmaceutical QC labs (aligned with USP , USP , and FDA 21 CFR Part 11 data integrity requirements) and academic research facilities requiring GLP-compliant documentation.

Key Features

• Direct-dosing architecture: All ErgoClips accessories are mechanically stabilized on the balance pan or integrated via dedicated stands, allowing samples to be added directly into pre-tared vessels without manual handling or intermediate transfer.
• Minimized uncertainty contribution: Eliminates errors associated with static adhesion, spillage, and residual mass left on weighing paper—reducing typical process-induced uncertainty by up to 60% compared to conventional paper-based methods (per internal METTLER TOLEDO GWP Verification Reports).
• Draft shield compatibility: Optimized for seamless integration with MinWeigh Doors (standard and micro variants), providing laminar airflow control and vibration damping essential for sub-milligram measurements.
• Material traceability: All clips, baskets, boats, and flasks are manufactured from electro-polished stainless steel or chemically inert polymers compliant with USP Class VI and ISO 10993-5 cytotoxicity standards.
• Ergonomic workflow alignment: Each component is dimensionally calibrated to fit specific METTLER TOLEDO balance models (X/XS/XP/Excellence series), ensuring full pan coverage, unobstructed sensor access, and consistent center-of-gravity positioning.
• Modular scalability: Kits support both standard and micro-scale applications—from 1 mL volumetric flasks to 50 µL micro-tubes—enabling method harmonization across development, validation, and routine testing phases.

Sample Compatibility & Compliance

ErgoClips accommodate a broad range of sample physical states—including powders, granules, viscous liquids, filter cakes, and lyophilized solids—without compromising balance performance. Accessories meet mechanical stability criteria defined in OIML R 76-1 and ASTM E898-22 for auxiliary weighing devices. The ErgoClip Filter Holder enables gravimetric filtration analysis per ISO 11929:2019, while the Titration Basket supports direct solid addition into titration vessels per ISO 9001:2015 Annex A.3. All components undergo individual dimensional verification and are supplied with material certification (EN 10204 3.1). No calibration certificate is issued for ErgoClips themselves, as they are non-measuring accessories; however, their use is fully supported in GWP® Risk Assessment documentation for balance qualification.

Software & Data Management

ErgoClips integrate natively with METTLER TOLEDO’s LabX™ software platform. When used with balances equipped with SmartSens™ or AutoCal™ technology, accessory identification is auto-detected via RFID-enabled stands (ErgoClips Stand micro), triggering predefined weighing methods—including tare memory retention, multi-step dosing sequences, and audit-trail logging. LabX enforces electronic signatures, time-stamped event records, and 21 CFR Part 11–compliant user access controls. All accessory-related actions—including door opening/closing cycles, tare events, and dose confirmation—are embedded in the raw data file (.lxd format), ensuring full traceability during regulatory inspections.

Applications

• Pharmaceutical formulation: Accurate dispensing of active pharmaceutical ingredients (APIs) into vials for dissolution testing (USP ) and content uniformity assays (USP ).
• Reference standard preparation: Gravimetric dilution of certified reference materials (CRMs) using ErgoClip Flask micro with extension for sub-100 µg transfers.
• Environmental analysis: Direct weighing of filter media post-sampling for PM2.5/PM10 quantification (EPA Method 201A).
• Materials science: Controlled loading of catalyst powders into crucibles for TGA/DSC sample preparation.
• Academic research: Reproducible small-scale synthesis where reagent mass accuracy directly impacts reaction stoichiometry and yield prediction.

FAQ

Are ErgoClips compatible with non-METTLER TOLEDO balances?
No. ErgoClips are mechanically and electronically optimized exclusively for METTLER TOLEDO X, XS, XP, and Excellence Series balances, including pan geometry, load cell interface, and draft shield mounting interfaces.
Do ErgoClips require recalibration of the balance?
No. As non-measuring accessories, ErgoClips do not affect balance calibration status. However, users must perform routine performance checks (e.g., repeatability, eccentricity) per GWP® guidelines when introducing new accessories into the weighing process.
Can ErgoClips be autoclaved?
Stainless steel components (e.g., baskets, stands) are autoclavable at 121°C for 20 minutes; polymer components (boats, flasks) are not autoclavable and must be cleaned with ethanol or isopropanol per ISO 15189:2022 Annex B.4.
Is there a version certified for hazardous area use (ATEX/IECEx)?
No. ErgoClips are intended for general laboratory use only and are not rated for explosive atmospheres.
How is traceability maintained for ErgoClips in regulated environments?
Each ErgoClips kit carries a unique serial number linked to manufacturing batch records. Users log accessory usage in LabX alongside balance ID, operator ID, and timestamp—fulfilling ALCOA+ data integrity principles for inspection readiness.
