The LyoPro Economic Benchtop Freeze Dryer by Antech Scientific is a practical and efficient solution for laboratories in South Africa. Available from Apex Scientific, this compact unit delivers high performance while maintaining a small footprint, making it perfect for cost-conscious research environments.
Intuitive Controls and Smart Features
The 7” touch screen runs the LyoSmart operating system, which streamlines the freeze-drying process. Users can easily program and adjust each step, while real-time control of the vacuum degree helps reduce drying times. The system includes built-in ice condenser coils, fast defrost via integrated hot gas, and an automatic non-return venting valve to protect against vacuum pump oil mist.
Quiet, Accurate Performance
The LyoPro operates quietly at just 48–52 dB(A), and its high-precision Pirani vacuum sensor measures with 0.001 mbar accuracy. These features ensure stable and reliable performance throughout every cycle.
LyoSmart Operating System
LyoSmart provides a user-friendly interface for displaying condenser temperature and vacuum data. Whether using manual or automatic modes, users can control each phase of the process and easily review results using the historical data recorder.
Efficient Vacuum Control
The system offers full vacuum control and duration settings. This level of flexibility can reduce freeze-drying time by up to 40%. Additionally, real-time vacuum levels are always displayed for better oversight.
One-Touch Operation
With its convenient “one-button” controls, users can start, stop, vent, or defrost the unit quickly. This minimizes the risk of contamination and simplifies day-to-day use.
Fast Cooling for Versatile Use
The LyoPro’s cooling system can reach -85 °C in just 10 minutes. This makes it ideal for a wide range of applications, especially those involving organic solvents.
Easy and Reliable Sealing
The flat flange and L-shaped sealing ring eliminate the need for manual pressure or vacuum grease. This design provides a long-lasting seal that ensures reliable performance with minimal maintenance.
