Optimatm Max and Max-E Ultracentrifuge (6.0.13) First time you use the centrifuge you must have personal instructions!!!!! User instructions: 1. Prepare your sample(s) in the centrifuge tube(s) that fit the rotor in the centrifuge. 2. If you have an unequal number of samples make an extra tube with water. 3. It is important that you make them weigh exactly the same. 4. Place the two tubes opposite of each other in the rotor. 5. You must place the tubes in the rotor before you put the rotor in the centrifuge. ( Rotor can be found in the fridge in lab 6.0.19) 6. If you have more samples you repeat no. 3 and 4 until you have all your samples in the rotor. 7. VERY IMPORTANT: The samples must be placed two by two opposite of each other to keep the rotor balanced when running. 8. Place the lid on the rotor. 9. Turn on the power on the front. 10.
