Key Design Features
Space-Saving Rotary Doors: The innovative rotary door design ensures the balance requires no extra space when doors are open, making it ideal for tight confines such as glove boxes and fume hoods. Multiple balances can be set up back-to-back on crowded lab benches. The breeze break top pivots left or right to allow easy access to flasks and beakers.
Quick Detachment Breeze Break: The breeze break detaches in seconds, even while wearing heavy gloves, for easier cleaning and top-loading operation. The rugged, shatterproof breeze break features anti-static coating for safe use in challenging applications where contamination is a concern.
High-Speed Operation: The 2-second stabilization time increases productivity by delivering fast results with frustration-free weighing down to 0.1 mg resolution.
