Efficient Compound Libraries With the XP56 Microbalance

Dosing Valuable Substance Compound libraries are not only responsible for the storage of several thousand different substances but also for further distribution. Laboratory staff can identify potentially active compounds in the database for their individual experiments and order a small amount from stock. Thereafter, the substances need to be aliquoted into small final tubes. These compounds are costly and sometimes toxic, making it essential to eliminate waste whilst dosing just a few micrograms. Therefore as many unnecessary handling steps as possible should be eliminated from the dosing process. Easy dosing with the XP56 Direct dosing into the final tubes is easily possible using the XP56 microbalance; no more sample transfer is needed. Exact weighing of the smallest quantities is possible due to the readability of 1 μg and a capacity of 52 g. With METTLER TOLEDO’s ErgoClips, different micro vessels can be fixed tightly onto the SmartGrid weighing pan and the angle adjusted for best ergonomic dosing. The weighing time can be optimized when using the MinWeigh Door micro, which reduces air turbulence in the weighing chamber therefore maintaining much faster stabilization times. All in all, the XP56 significantly optimizes the efficiency of daily work in a compound library.
