Atlas Turbidity System benefits Sensitive:  The Atlas Turbidity Probe has a very high      signal to noise ratio. Inert construction:  All wetted parts are quartz      glass/PTFE/FFKM. Automatic data-logging:  Turbidity can be monitored      from the intelligent Atlas Base Unit and downloaded by      USB without PC control. Advanced controlled:  With the Atlas PC Software      the system can crystalize along a turbidity ramp,      determine the metastable zone, etc. Easy to use:  The Turbidity is displayed on the Atlas      Base and can be plotted in real time using the Atlas      Software. Wide temperature range:  Atlas Turbidity System      offers a temperature range of -80 to >200°C. Easy calibration:  Simple 2-point calibration gives a 0-      100% turbidity range. Compact:  The Turbidity probe can be used with any      Atlas reactor. Infra red optics:  Unaffected by ambient lighting      changes. Intelligent:  The Atlas Turbidity system can perform      automated crystallization studies, varying concentrations      and temperatures. Atlas Turbidity System features The Atlas Turbidity System is ideal for use in processes that involve crystallisation steps. In these processes it is often essential to ensure downstream solids handling, filtration, milling, drying, etc. is consistent and efficient. The use of turbidity monitoring with Atlas is ideal for providing this information as it is simple, repeatable and provides both process, engineering and safety information.

Typical Applications The Atlas Turbidity System can be used in wide range of applications. The Turbidity Probe can be used as a simple crystallization point detector, or in more complex studies of metastable crystallization zones, secondary nucleation and  polymorphism issues. A list of typical applications can be seen below: Crystallization Studies           - Automated metastable zone width studies           - Optimisation of product recovery - crystal size,             purity and recovery Crystallization Control           -  Crystallize along turbidity ramp Scale-up Synthesis            -  Batch-to-batch repeatability            - Agitation effects Polymorphism Studies            - Impact of different solvents, mixtures,              concentrations and temperatures           - Impact of crystal “seeding” A typical Atlas Turbidity System contains:
