Carefully lower a Magnetic Stir Bar Retriever into the neck of the 5-mL Conical Vial to remove the Magnetic Spin Vane from the reaction solution. (Note: It is very important that the tip of the Magnetic Stir Bar Retriever does not come into contact with the liquid in the 5-mL Conical Vial; this could contaminate the liquid and oblige you to start the experiment over.)
