Page 13: Installing Theflask Adapters
Flask Adapters Place the hotplate-flask adapters on the hotplates. Take care that the adapters are seated securely on the hotplates and cannot slip off sideways. Inserting the Glassware To minimize the risk of breakage, always hold all glassware in the vicinity of the standard taper joint! Lay the cross-shaped distance parts into the hotplate-flask adapters. The round-bottom flasks must not be immediately inserted in the hotplate- flask adapters; otherwise they could break on heating. Never operate your in-line extraction unit without the distance parts! Place the round-bottom flask in the flask adapter on the hotplate. Check once more the height of the crossbars with extractor mounts. The upper end of the neck of the round bottom flask must protrude several millimeters into the lower opening of the extractor mount. This will secure the flask against tipping over. If necessary, adjust the height of the crossbars. – 13 – © behr Labor-Technik GmbH... - Page 14 ® In-Line Extraction Unit Insert the extractors from above into the extractor mounts and seat them on the round-bottom flasks. The upper horizontal segment of the extractor mounts have a slot in front. In If you are using the event that you are using an extractor an extractor with spigot: guide the with spigot (for example, the behrotest ® spigot through EZ 100 H), then guide the extractors this slot with the spigots carefully through these slots. Insert the reflux condensers onto the extractors. – 14 – © behr Labor-Technik GmbH...

Lay the hose to a sink or other drain. Make sure that there are no tight curves or kinks in the hose. If necessary, shorten the hose to prevent constrictions of this nature. Connections to the Condensers Attach the silicone tubing segments to the tubing nipples on the cooling water distribution unit identified as „Out“ (outflow) and „In“ (inflow). Attach the tubing segments to the condensers. The lower nipple on the reflux condenser is for water inflow. Connect the tubing segments coming from the lower „In“ panel of the cooling water distributor to these nipples. Connect the upper nipples of the condensers in the same manner with the upper „Out“ panel of the cooling water distributor. – 16 – © behr Labor-Technik GmbH...

Page 20: Sample Preparation
Now fill solvent into the round-bottom flask. Place the flask on the hotplate flask adapter (2) and insert the extractor into the mouth of the flask (3). Attach the reflux condenser to the extractor and start the flow of cooling water. Switching the Heating Unit On Turn the power switch on the front of the inline heating unit to the „I“ position. behrotest ® The power switch of the inline heating unit fulfills two functions. It serves to turn the apparatus on and off and also contains a built in electrical circuit-breaker The circuit-breaker operates similarly to those in household appliances – it shuts off the electrical power supply Since this safety feature (circuit-breaker) requires cocking a spring, turning the power switch of the inline heating unit to the on position will require somewhat more force than a simple on/off switch – 20 – © behr Labor-Technik GmbH... -
Page 21: Starting The Extraction
The yellow „HEATING“ indicator lamps of each heating position indicate heating activity. Finishing the Extraction If you are using an extractor with stopcock, you can now evaporate the solvent. Draw the solvent that is accumulating in the extractor off in portions; collect it in a bottle that can be properly closed. Afterwards, shut the energy controls down and then switch the in-line heating unit off with the MAIN SWITCH. If you are using an extractor without stopcock, the easiest will be to evaporate the solvent with a rotary evaporator: Shut the energy controls down to zero and then swith the in-line heating unit off with the main switch. Wait till the solvent has ceased boiling. Take the condensers off the round- bottom flasks and place them in the borings of the condenser stand. Cautiously take the extractors off the roundbottom flasks; be careful not to let the solvent run through the siphon while you are doing this. Collect the solvent in a bottle that can be properly closed. Take the round-bottom flasks out of the device and insert them in your rotary evaporator. – 21 – © behr Labor-Technik GmbH... -
