Celsius® S3 System with US Computer FTH-CS00000-0001 Scale down tool for process development Linear scalability Multiple F-T cycles Stable samples Celsius® S3 is the only laboratory instrument to evaluate the freeze and thaw processes of new drug candidates in single-use containers. This system is a tool to execute freeze-thaw process development and stability studies using a minimal amount of product. It is composed of a temperature controlled unit (CryoPilot A), a module for bag insertion (S3 Module), a mixing plattform for the thawing steps (CryoMixer Jr), a computer with data acquisition system and a custom-built software (CryoPilot Software) and single-use bags (Celsius®-Pak 30 ml and 100 ml).
