UYA 2.4Y PLUS Ultra-Microbalance

Category Laboratory Balances
Manufacturer Radwag
Country of manufacture Poland

The UYA 2.4Y PLUS ultra-microbalance is a professional instrument intended for the most demanding applications. The innovative SYNERGY LAB line guarantees the highest quality, precision and reliability.

The best possible repeatability and USP regulations conformity
The best weighing accuracy and repeatability – with sd ≤ 1d combined with USP regulations conformity (Section 41 and 1251) make 2.4Y PLUS balances a new standard for mass measurement quality.

Ergonomic Mechanical Design
The UYA 2.4Y PLUS ultra-microbalance features construction solutions ensuring convenient everyday operation. The weighing chamber can be disassembled without tools, which makes cleaning it convenient. Programmable infrared sensors, when respectively set, enable touchless opening and closing of the weighing chamber.

Antistatic Weighing Chamber
Specially designed antistatic panes coating compensates electrostatic charges accumulated on the sample and laboratory accessories. With this, the influence of electrostatics onto the weighing result is limited.
