CP Series Milligram Balance
Sartorius CP225D

Twenty-three models — from 0.01 mg to 34 kg — offer value for a variety of laboratory weighing applications that offer an excellent return of your investment.

Just one glance tells you that the bold new design of the balance provides the highest level of user-friendliness.  For instance, the unique new, triangular weighing pan shape on many CP models, provides space age design with down to earth usefulness.  That is, by providing more space than most common pan shapes.  Another practical feature of the CP is that it is so easy to use and can adapt to accommodate your weighing needs as they change.

Sartorius GP Series Precision Balances
Sartorius GP Series precision balances produce steady readings using the high stability mode and the unique Sartorius weighing system even if the environmental conditions are not ideal for precision weighing.  The Double Lever System, or DLS, for short based on its special force transmission design.  The proven monolithic systems is cut from a single block of a special, highly rugged aluminum alloy using high-speed 21st century milling technology.  The double lever principle offers two decisive advantages: the design in the area of the pan linkage is highly resistant to mechanical stress and therefore has exceptionally high mechanical stability, and the system is about half the size of the monolithic block cell, allowing for a smaller footprint.  Like the monolithic weigh cell, it is cut from a single block of aluminum and no screw fasteners are needed between functional parts.  This keeps the system less sensitive to fluctuations in temperature, and with fewer parts there is less chance of failure.
