REVO® Research and Development Freeze Dryer

REVO Freeze Dryer

Development & Small Scale Production

The REVO Research & Development Freeze Dryer has the largest shelves and best shelf-to-shelf spacing of any freeze dryer in its class offering up to 12 sq ft (1.115 sq M) of shelf area and a condensing rate of 20 Liters in 24 hours. This allows for more product throughput in the same floor space. Using the best components and design techniques combined with the most advanced PC/PLC control system, the REVO R&D Lyophilizer offers data collection and self-testing features. Overall, the REVO R&D Freeze Dryer is the perfect solution for both your protocol development and small scale lyophilization production needs.

Our easy-to-use software provides automatic freeze drying, defrost, system and leak rate testing. Data can be printed either numerically or graphically. This same control system is used on industrial dryers, allowing scaling to production. An interactive maintenance screen simplifies component servicing. All systems are remotely accessible, with customer approval, for trouble-shooting process issues. Now available with Clean in Place.

  • 5 shelf pull down from +20 to –40C in less than 30 minutes
  • Vacuum pull down to 100 mT in less than 20 minutes
  • Vacuum leak rate less than 30 mT per hour
  • Vacuum level 10 mT in clean dry system (-85)
