Microbalance
0.001 - 50 g
Martin Christ
With the unique CHRIST micro balance you can monitor the progress in the drying process without any influences to the process. The transition from sublimation to desorption can be determined as well as the drying speed using different p,T-profiles. Thus the drying cycles can be optimized. You obtain stable products without the need of needlessley long drying cycles. Limitations: The high accuracy of measurement is limited to -40°C ... +40°C and the balance can't be used in sterile processes.
The weighing system operates on extreme temperatures and under vacuum and remains in the unit during the entire drying process.
The vials are positioned directly next to the other vials on the shelf. Therefore, the results are fully compatible.
Based on the continuous measurement there is the possibility to monitor the drying speed during various phases of the process under different drying conditions.
The end of drying can be safely determined via the weight loss.
