RADWAG XA 21/52.5Y.M.A XA 5Y.M.A Microbalance, 21/52g Capacity, 1/5µg Readability, 21 CFR Part 11, Internal Calibration, OIML Class I

RADWAG XA 21/52.5Y.M.A Microbalance — Dual-Range Microgram Precision with Full Automation

Complex weighing protocols sometimes require microgram sensitivity for small samples and extended capacity for heavier tare vessels on the same instrument. The RADWAG XA 21/52.5Y.M.A Microbalance resolves this challenge with dual ranges — 21 g at 1 µg and 52 g at 5 µg — backed by automated doors, automatic leveling, and 21 CFR Part 11 compliance.

Key Features

• Dual-Range Operation (21 g / 52 g): Switch seamlessly between 1 µg and 5 µg readability depending on load, eliminating the need to transfer samples between a microbalance and an analytical balance.
• Automatic Draftshield and Leveling: Motorized chamber doors and the ReflexLEVEL system reduce human-induced vibration and geometric error, critical factors at microgram resolution.
• 21 CFR Part 11 Firmware: Electronic signatures, encrypted audit trails, and role-based access control satisfy documentation requirements for GMP and GLP-regulated workflows.
• RFID and NFC Compatibility: Tag samples, containers, or formulation ingredients in the database, and authenticate users via contactless cards for fast, secure operation.
• 10-Inch Touchscreen with Remote Access: The ELLIPSIS terminal supports hotspot connectivity, allowing operators to monitor and control the balance from a phone, tablet, or computer.
• Digital Weighing Auditor (DWA): Monitors ambient conditions, leveling status, calibration due dates, and USP compliance in real time, alerting users before conditions degrade.

Detailed Overview

The XA 21/52.5Y.M.A leverages RADWAG's 5Y electromagnetic force restoration sensor with optimizations for microgram-scale operation. Standard repeatability at 5 % of the primary range is 1.5 µg, while linearity is maintained within ±20 µg across the full 52 g span. The ø30 mm weighing pan is purpose-sized for small samples and capsules. Stabilization occurs in approximately 3.5 seconds, maintaining throughput even in multi-sample sequences. Comprehensive connectivity — USB-A, USB-C, HDMI, Ethernet, Wi-Fi, and Hotspot — facilitates integration with LIMS, networked printers, and remote display terminals across multi-site operations.

Applications

• Micro-dosing and capsule filling verification in pharmaceutical production
• Small-component mass determination in electronics and aerospace manufacturing
• Trace-level residue quantification in environmental testing
• Reference weight certification in calibration service laboratories

Why Choose the RADWAG XA 21/52.5Y.M.A?

This dual-range microbalance is ideal for teams that require both microgram sensitivity and extended tare capacity in one footprint. Automated environmental controls and regulatory-ready firmware streamline compliance, while remote connectivity keeps supervisors informed without approaching the instrument. Order the XA 21/52.5Y.M.A to consolidate precision weighing tasks in your laboratory.
