Page 18: Description Of Function
4 .1 Instrument function There are several important components integrated into the B-811 extraction system which allow you to use the instrument for many kinds of applications in the area of solid-liquid extraction. 1. The solvent and extract only come in contact with glass and PTFE. This allows the instrument to be used for applications in the area of residue analysis (e.g. -

The number of cycles and/or time defines the length of the extraction process. If the programmed number of cycles is reached and/or the extraction time is up, all valves are opened and the solvent is released into the beaker. Then the program switches to the next step.

When the rinsing time (step 2) is expired the program switches to step 2a. The samples are lifted up automatically. Then the valve closes and the solvent evaporates, rises up to the condenser and condenses. The freshly condensed solvent is collected in the extraction chamber.

Page 29: Putting Into Operation
NOTE We recommend to operate the instrument under a fume hood if e.g. diethyl ether or chloroform are used. Do not operate the Extraction System B-811 under the same fume hood as the hydrolysis unit. ATTENTION To ensure the instrument safety do not place any object on top of it. -
Page 30: Mounting The Glass Parts
Make sure that there is enough solvent in the extraction chamber so that the solvent level you have set will be reached. NOTE Some samples absorb a lot of solvent. You may have to add more solvent so that the required solvent level is reached in the extraction chamber. B-811 Operation Manual, Version H... -
