RADWAG XA 21.5Y.M XA 5Y.M Microbalance, 21g Capacity, 1µg Readability, 21 CFR Part 11, Internal Calibration, OIML Class I

RADWAG XA 21.5Y.M Microbalance — Sub-Microgram Precision for Demanding Research

When your research demands measurement resolution at the microgram level, the RADWAG XA 21.5Y.M Microbalance delivers with 1 µg readability and a 21 g maximum capacity. Designed for regulated laboratories requiring full 21 CFR Part 11 compliance, this instrument combines advanced weighing technology with comprehensive data integrity features to support pharmaceutical, biotechnology, and environmental testing workflows.

Key Features

• Microgram-Level Resolution: With 1 µg readability and standard repeatability of 1.3 µg at 5% load, this microbalance enables precise quantification of trace-level samples critical for pharmaceutical formulation and advanced materials research.
• Full Regulatory Compliance: Built-in support for 21 CFR Part 11 and EU GMP Annex 11 ensures electronic records, audit trails, and electronic signatures meet the stringent requirements of FDA-regulated environments.
• Intuitive 10-Inch Touchscreen: A large capacitive display with customizable widgets provides real-time environmental monitoring, balance status, and weighing results at a glance, reducing operator training time and improving workflow efficiency.
• Touch-Free Operation via IR Sensors: Programmable infrared proximity sensors allow hands-free control of taring, printing, and door functions, minimizing vibration and contamination during sensitive measurements.
• Automatic Internal Calibration: The motorized internal calibration system compensates for temperature drift and ensures measurement traceability without external weights, maintaining OIML Class I accuracy at all times.
• Comprehensive Connectivity Suite: Dual USB-A ports, USB-C, HDMI, Ethernet, Wi-Fi, and hotspot capability enable seamless integration with LIMS, printers, barcode scanners, and remote monitoring devices across your laboratory network.

Detailed Overview

The RADWAG XA 21.5Y.M Microbalance is engineered around the 5Y platform, which introduces a Digital Weighing Auditor (DWA) that continuously monitors ambient conditions, levelling status, calibration state, and USP compliance. This proactive diagnostic system alerts operators before environmental factors compromise measurement integrity. Semi-automatic levelling via the LevelSENSING system further streamlines daily readiness checks. The weighing chamber accommodates samples through manually operated doors, while RFID and NFC tag compatibility enables user verification and sample identification. Combined with remote device connectivity through phones, tablets, or computers, the instrument supports modern paperless laboratory practices without sacrificing analytical rigour.

Applications

• Pharmaceutical quality control and USP minimum weight verification
• Micro-sample preparation for environmental particulate analysis
• Filter weighing in emissions monitoring and air quality testing
• Advanced materials and polymer research requiring microgram sensitivity
• Biotechnology assay preparation and reagent dispensing
