RADWAG UYA 2.5Y UYA 5Y Ultra-Microbalance, 2.1g Capacity, 0.1µg Readability, Internal Calibration, OIML Class I
RADWAG UYA 2.5Y Ultra-Microbalance — 0.1 µg Resolution for the Most Demanding Mass Measurements
Certain metrological and research tasks push well beyond what standard microbalances can resolve. The RADWAG UYA 2.5Y Ultra-Microbalance reads to 0.1 µg with a 2.1 g capacity, serving as a primary reference instrument for mass metrology, ultra-trace sample preparation, and calibration of micro-weights at the highest accuracy level.
Key Features
- 0.1 µg (100 ng) Readability: Resolves mass changes at the sub-microgram level, enabling measurements that fall below the detection threshold of conventional microbalances.
- Automatic Internal Calibration: A motor-driven internal weight maintains sensitivity without manual handling of calibration standards, protecting the instrument from contamination at ultra-trace levels.
- ReflexLEVEL Automatic Leveling: Continuous level correction ensures geometric alignment remains precise, a non-negotiable requirement when measuring at 0.1 µg resolution.
- OIML Class I Certification: Confirms compliance with the most stringent accuracy class for laboratory weighing instruments, supporting traceable results in accredited calibration facilities.
- 10-Inch Touchscreen with Widgets: Displays environmental conditions, weighing history, and instrument status alongside measurement results, providing complete situational awareness during sensitive operations.
Detailed Overview
The UYA 2.5Y represents the pinnacle of RADWAG's 5Y electromagnetic force restoration platform. Standard repeatability reaches 0.15 µg at 5 % of capacity, and linearity is held within ±1.5 µg. The ø16 mm weighing pan is optimized for the small calibration weights, reference samples, and capsules typical of ultra-micro applications. Stabilization ranges from 10 to 20 seconds depending on sample size and environmental conditions — a reflection of the extreme sensitivity that requires very low noise floors. Connectivity includes USB-A, USB-C, HDMI, Ethernet, Wi-Fi, and Hotspot. The unit supports 21 CFR Part 11 with electronic signatures, audit trails, and multi-method user verification including RFID and NFC tags for contactless authentication.
Applications
- National metrology institute reference mass calibration
- Ultra-trace pharmaceutical active ingredient weighing
- Micro-weight manufacturing quality assurance
- Advanced materials research requiring sub-microgram precision
