Basic Research Freeze Dryer LyoAlfa

The LyoAlfa laboratory freeze dryers are particularly suitable for research centres requiring greater freeze drying capacity. This freeze dryer comes as a console and is mounted on casters which makes it easy to install. The unit is very flexible, allowing for the simultaneous freeze drying of bottles, vials or bulk products through the connection of different manifold systems or a chamber.

The LyoAlfa laboratory freeze dryer comes in 2 configurations:

  • LyoAlfa 15 -55, with a final condenser temperature of -53 ±3°C.
  • LyoAlfa 15 -85, with a final condenser temperature of -83 ±3°C. This enables a higher freeze drying speed and is much more suitable for working with biological samples or products with very low eutectic or collapse points.

The unit comes with a two-stage vacuum pump located inside the console.

All the critical parts are made out of AISI 316L stainless steel.

The easy-to-use control system can display the condenser temperature and the vacuum level at all times, as well as enabling adjustment of the shelf temperature when coupled to a drying chamber.

The LyoAlfa can be supplemented with a wide range of accessories such as the heated vial closing chamber, heated bulk product chamber, 8 or 16 connection manifold, auxiliary chamber for direct connection to the manifold, etc.

The unit comes in a standard configuration with RS232 interface for connection to a PC via suitable monitoring Lyologger software.
