The SP VirTis Ultra 35L is a pilot lyophilizer with a single product chamber design, which allows for larger batches and product uniformity. Shelf counts run from 4 to 15, so capacity can be matched to the real throughput rather than the other way around.
Key features
- Compact design for easy installation
- Single product chamber design allows for larger batches and product uniformity
- Available with a Merlin or LyoS 2.0 control system
- Optional bottom-up hydraulic stoppering system
- Narrow, non-cleanroom configuration available
