RADWAG XA 120/250.5Y XA 5Y Analytical Balance, 120/250g Capacity, 0.01/0.1mg Readability, 21 CFR Part 11, Internal Calibration, OIML Class I
RADWAG XA 120/250.5Y Analytical Balance — Dual-Range Precision with 21 CFR Part 11 Compliance
Analytical laboratories needing both semi-micro sensitivity and extended capacity in a single instrument will value the RADWAG XA 120/250.5Y Analytical Balance. Its dual-range design provides 0.01 mg readability up to 120 g and 0.1 mg readability to 250 g, all managed through a 10-inch touchscreen and secured by full 21 CFR Part 11 compliance for regulated pharmaceutical and research environments.
Key Features
- Dual-Range Operation (120/250 g): Automatically switch between 0.01 mg and 0.1 mg resolution depending on the load, giving operators semi-micro precision for lighter samples and extended capacity for heavier ones.
- 21 CFR Part 11 Ready: Secure user authentication, electronic signatures, and comprehensive audit trails protect data integrity in FDA-regulated workflows.
- 10-Inch Touchscreen with Widgets: A large, configurable display presents live environmental metrics, process guidance, and weighing data without leaving the home screen.
- Automatic Internal Calibration: Self-calibration triggered by temperature or schedule ensures traceable accuracy across shifts without operator involvement.
- Touch-Free IR Sensor Control: Proximity-activated taring, door opening, and printing reduce physical disturbances that compromise sensitive analytical readings.
- OIML Class I Verification: Meets the highest metrological accuracy class for legal-for-trade and regulatory compliance applications.
Detailed Overview
The XA 120/250.5Y sits within RADWAG's flagship 5Y analytical balance line, bringing the platform's intelligent features to a dual-range configuration. Standard repeatability of 0.005 mg at 5 % load confirms semi-micro performance in the lower range, while the expanded 250 g capacity accommodates larger flasks and tare vessels that would exceed many analytical balances. The ReflexLEVEL semi-automatic levelling system guides operators through precise bubble-centre alignment, and the Dynamic Weighing Advisor monitors ambient conditions alongside USP minimum-weight compliance in real time. Connectivity via USB-A, USB-C, HDMI, Ethernet, Wi-Fi, and mobile hotspot ensures flexible integration with LIMS, external monitors, and remote-access devices.
Applications
- Pharmaceutical quality-control assay preparation
- Semi-micro analytical chemistry in R&D laboratories
- USP/EP reference-standard weighing
- Environmental and food-safety testing requiring high resolution
