Overview
The METTLER TOLEDO MA95 Analytical Balance is a precision laboratory weighing instrument engineered for routine analytical and quality control applications in regulated and non-regulated environments. Based on electromagnetic force compensation (EMFC) technology, the MA95 delivers high reproducibility and long-term stability under standard laboratory conditions (20 ± 5 °C, ≤ 60% RH). Its design prioritizes operational robustness, intuitive interaction, and compliance-ready functionality—making it suitable for laboratories performing GxP-aligned tasks where traceability, data integrity, and user-guided workflows are essential. The balance operates with a resolution of 0.1 mg (100 g capacity), meeting minimum performance requirements for general analytical weighing per USP , ISO/IEC 17025, and ASTM E898-22 guidelines.
Key Features
- Electromagnetic force compensation (EMFC) sensor architecture ensures high linearity, low drift, and resistance to environmental perturbations such as air currents and temperature gradients.
- High-brightness, backlit LCD display with large, legible digits (18 mm height) and on-screen step-by-step guidance for common weighing procedures—including tare, net/gross, percentage, and density determination.
- Capacitive touch-key interface with haptic feedback provides responsive, glove-compatible operation and reduces mechanical wear compared to membrane or mechanical switches.
- Integrated internal calibration routine using factory-traceable reference weights; supports scheduled auto-calibration (e.g., at startup, after temperature shift >1.5 °C, or at user-defined intervals).
- Chemically resistant glass draft shield surface and stainless-steel pan assembly facilitate rapid decontamination and minimize residue retention—critical for multi-sample workflows in QC labs.
- Modular connectivity via RS232 serial port and USB-A host port enables direct integration with label printers, LIMS workstations, USB flash drives, and networked PCs without requiring proprietary adapters.
Sample Compatibility & Compliance
The MA95 accommodates standard analytical sample containers (e.g., weighing boats, vials, crucibles) up to 100 g nominal load. Its draft shield design complies with ISO 9001:2015 and ISO/IEC 17025:2017 requirements for environmental isolation during sensitive measurements. While not certified for Class I, Division 1 hazardous locations, the unit meets CE marking directives (2014/30/EU EMC, 2014/35/EU LVD) and RoHS 2011/65/EU material restrictions. For regulated environments, audit trails can be generated via optional METTLER TOLEDO LabX Lite software (not bundled), supporting ALCOA+ principles and partial alignment with FDA 21 CFR Part 11 when deployed with appropriate system controls.
Software & Data Management
Data export is supported natively through ASCII-formatted serial output (RS232) and mass-storage-class USB transfer. The balance outputs timestamped weight values, units, stability status, and operator ID (if configured via external authentication system). When connected to a Windows-based workstation running METTLER TOLEDO’s free Basic Data Transfer Utility, users can log sessions directly into CSV or Excel-compatible formats—with column headers mapping to GLP-relevant metadata (date/time, gross/net/tare, deviation flags). No embedded database or electronic signature capability is present in the firmware; full Part 11 compliance requires external validation of the complete data acquisition chain.
Applications
- Raw material verification and batch release testing in pharmaceutical and chemical manufacturing.
- Preparation of standard solutions and titrant calibration in analytical chemistry laboratories.
- Content uniformity testing per USP and weight variation checks for solid dosage forms.
- Moisture content estimation via loss-on-drying (LOD) when integrated with compatible heating modules (external).
- Educational use in university teaching labs requiring ISO-compliant entry-level analytical instrumentation.
- Environmental testing labs performing gravimetric analysis of particulate matter (e.g., PM10, PM2.5) filters.
FAQ
What is the readability and maximum capacity of the MA95 Analytical Balance?
The MA95 offers 0.1 mg readability with a 100 g maximum capacity.
Does the MA95 support internal calibration with motorized mechanisms?
No—it uses manual or user-initiated internal calibration with fixed reference weights; no motorized calibration drive is included.
Can the MA95 be validated for GMP environments?
Yes, when used within a documented IQ/OQ/PQ protocol and paired with compliant data handling systems, it satisfies foundational GMP weighing requirements per EU Annex 11 and WHO TRS 992.
Is the balance compatible with METTLER TOLEDO’s LabX software platform?
It supports basic LabX Lite functionality for data capture and export but lacks native LabX full-feature integration (e.g., method management, electronic signatures).
What maintenance is required to ensure long-term accuracy?
Annual verification using NIST-traceable weights and periodic cleaning of the weighing chamber and draft shield surfaces are recommended per METTLER TOLEDO Service Bulletin SB-MA95-2023.
