Incremental condensing performance for every application.

In addition to selecting the accessories, the following criteria should be taken into account when choosing a freeze-drying system:

• required ice condenser temperature (-55 C for water-based samples, -85 C for substances with low freezing points or containing solvents)
• number of shelves, i.e. number of flasks needed for the amount of product per batch
• maximum ice condenser performance required (kg/24h) i.e. total quantity of ice produced until defrosted

• Freezing and drying inside ice condenser chamber (process A) on one temperature controlled shelf (ø 200 mm, total area = 0.031 m²)
• Freezing and drying inside ice condenser chamber (process A) on one temperature controlled shelf with stoppering device (ø 200 mm, total area = 0.031 m²)
• 2 drying chambers with 24 ports for flasks, wide-neck filter bottles or distributors for ampoules
• Manifold for 8 round bottom flasks, wide-neck filter bottles or distributors for ampoules, specially suited for the drying of solvents
• 5 heatable shelves (ø 200 mm, total area = 0.155 m², distance between shelves = 25 mm - can be varied by removing single shelves) additional ports for 12 round bottom flasks, wide-neck filter bottles or distributors for ampoules
• 10 heatable shelves (ø 200 mm, total area = 0.31 m², distance between shelves = 25 mm - can be varied by removing single shelves)
• 10 heatable shelves (ø 200 mm, total area = 0.31 m², distance between shelves = 25 mm - can be varied by removing single shelves) additional ports for 12 round bottom flasks, wide-neck filter bottles or distributors for ampoules
• 2 heatable shelves with stoppering device (ø 250 mm, total area = 0.09 m², distance between shelves = 45 mm - can be increased to 110 mm by removing one shelf) additional ports for 12 round bottom flasks, wide-neck filter bottles or distributors for ampoules
• 4 heatable shelves with stoppering device (ø 250 mm, total area = 0.18 m², distance between shelves = 50 mm - can be varied by removing single shelves)
• 5 heatable shelves (ø 375 mm, total area = 0.55 m², distance between shelves = 67 mm - made possible with special adapter plate)
• 1 drying chamber with additional ports for 12 round bottom flasks, wide-neck filter bottles or distributors for ampoules, additional connection to a rotation vacuum concentrator (e.g. RVC 2-25) available
