The LyoStar3 is designed to meet the needs of R&D professionals. Our freeze drying equipment is used for applications ranging from process development for scale-up to product processing for stability studies to formulations work. Models are available in stoppering and bulk configurations.  The LyoStar is an R&D and process development freeze-dryer that provides unmatched process accuracy, reliability and unique ease-of-use features. The LyoStar features Type T thermocouple-controlled shelf temperature accuracy of +/- 0.5°C or better and vacuum control within 0.1% of set-point. Its robust 5.5 hp cascade refrigeration system enables shelf pull down from ambient to –40°C in less than 25 minutes, and the ultra-reliable scroll compressors feature just 3 moving parts.  LyoStar3 is available with Praxair ControLyo™ Nucleation on Demand Technology.

LyoStar3 Key Features:

  • SMART Freeze-Dryer Technology helps automate and shorten the development of freeze-drying cycles
  • Delivers product information that has previously been unavailable during a cycle – dried layer resistance, heat flow and mass transfer
  • Designed to facilitate scale up bu maximizing features in comon with well-designed commercial systems
  • Configured with superior instrumentation for complete process information – isolation valve, capacitance manometers, Pirani gauge, 16 thermocouples, Allen Bradley PLC
  • Available with 21 CFR Part 11 compliant software and full validation packages
