When your focus is accuracy, ease of use, and saving precious samples, look no further than the new XPR Excellence line from METTLER TOLEDO. The latest Excellence XPR Analytical and Micro-Analytical models - including the brand-new XPR106DUH, which is unique in the marketplace - are designed to outperform other balances. Through design innovation, METTLER TOLEDO experts have increased maximum load in both full and fi ne ranges while maintaining repeatability. This means smaller samples can be weighed-in to heavier tare containers, resulting in greater ease and material savings. These benefi ts are further enhanced because of a reduced need to transfer or back-weigh very small samples for true ‘right fi rst time’ results. The addition of integrated antistatic protection (50% off for a limited time) adds an even higher level of assurance when you weigh your smallest, most precious materials.
