SP Hull LyoStar 4.0

The LyoStar4 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 RTD-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.
