Freeze drying microscope provides clearer images for easier analysis

Biopharma Technology Ltd (BTL) has released the Lyostat4, its latest freeze drying microscope. Freeze drying microscopy (FDM) is an established technique for establishing the point of collapse, the most important critical temperature for developing safe and robust freeze drying cycles. Essentially operating as a micro freeze dryer, FDM enables freezing and drying of a real sample to be observed in real time.

As FDM analysis is based on visual identification rather than thermal data, it is of the utmost importance to ensure maximum image clarity and resolution. According to BTL, the Lyostat4 provides the latest generation LED light source for an even sharper image; it is brighter than the previous Halogen illumination but at the same time generates significantly less heat. This is accomplished by combining the LED source with an efficient, custom-designed electronics module. It is claimed that the LED system also provides superior longevity with a maintenance-free lifetime of more than 60,000 hours and nominal electrical power consumption for operation savings and green credentials.

Lyostat4 is compact, saving 20 x 21 cm bench space over Lyostat3. Used with the new stand, which eliminates trailing cables, the footprint can be reduced to just 45 x 30 cm (not including vacuum pump).
