Total ice capacity 4 kg,
Ice condenser temperature -105°C.
It is common practice to use freeze drying not only for aqueous samples but also for HPLC fractions containing solvents such as acetonitrile, TFA and other alcohols or for products containing t-butanol, DSMO and so on.
The new freeze dryer Alpha 3-4 LSCbasic is a special system for freeze drying of organic samples containing solvents. It allows for safe freeze drying of the commonly flammable solvents and an improved separation due to the very low ice condenser temperature. Alpha 3-4 LSCbasic is especially resistant to solvents and meets increased safety requirements for commonly flammable solvents.
The specialized system is available in two different packet configurations. The solvent packet flask consists of a manifold with 12 chemical-resistant valves for flasks. The universal solvent packet contains 3 unheated shelves Ø 265 mm as well as 12 chemical-resistant valves for flasks.
