A bottle is connected to the bottom of the cleaner, and the water pump is opened when one end of the nozzle is connected to the pump. 3. Pour acetone at one end of the dumped solvent, and acetone will run straight into the inverted NMR tube to wash out the lipid material. Pour in the ethanol, then pour in the water, and then pour the acetone. 4.
