INSTRUCTION MANUAL-CoolSafe Freeze Dryersmodels Page 10 / 19 The drain valve is located at the front, and is used for draining the ice condenser after de-icing. 5. Operation The freeze drying process is a balance between the heat absorbed by the sample to vaporize the ice, and the heat removed by the condenser to convert the water vapor into ice.
INSTRUCTION MANUAL-CoolSafe Freeze Dryersmodels Page 12 / 19 5.2. Preparations Check that the CoolSafe ice condenser is free from ice and water, and that all valves i.e. the drain valve is closed.. Check that there is no water in the drain valve. ...

Start the application of the vacuum by opening the vacuum valve and check that the AWO-Indicator stays green indicating OK for freeze-drying. 3. Connect a flask to an appropriate cone on the rubber valve. Turn the rubber valve to position (B). The AWO-Indicator should always be green prior to connecting the next flask.
INSTRUCTION MANUAL-CoolSafe Freeze Dryersmodels Page 14 / 19 5.4. Freeze-drying using chambers 1. Make sure that the (external) vacuum valve is closed. 2. Mount the chamber and shelf arrangement on the CoolSafe. Check that all connections are tight and the chamber is closed. If heated shelves are to be used, refer to the controller manual. 3.
INSTRUCTION MANUAL-CoolSafe Freeze Dryersmodels Page 15 / 19 5.6. Stopping the vacuum pump Close the (external) vacuum valve and let the pump run for a minimum of 45 minutes after the freeze-drying has ended. This is to avoid any possible condensates remaining in the pump oil. If the freeze dryer is used regularly during the week, it is recommended that the vacuum pump runs constantly with gas ballast valve open and the vacuum valve closed.
INSTRUCTION MANUAL-CoolSafe Freeze Dryersmodels Page 16 / 19 7.3. Cleaning If a sample is spilled in the concentrator chamber, it must be cleaned up immediately. 8. The Freeze-drying process To understand the freeze-drying process, this section describes the theory for the process in short. For more detailed information about freeze-drying please consult available literature e.g.

The heating will initiate sublimation of the moisture from the product to the surrounding environment. The vapor will move to the condenser surface because of the lower vapor pressure in the condenser. ...
