• * The volume is the approximate amount of the sample.
• For example, in the ether extraction of rat urine, the cooler is removed and the urine is filled from the top of the 88 up to 10 mm to 15 mm below the top of the tube that runs from the bottom of the center.
• Next, turn on the condenser and evaporate the ether of 6, which is then refluxed by the condenser, enters the urine through a small sigmoidal tube, extracts it during the rise of the ether by specific gravity, overflows into the central tube, and returns to the flask.
