Specific guidance

Follow these guidelines when working with a centrifuge: 1 When loading the rotor, examine the tubes for signs of stress, and discard any tubes that are damaged. 2 Inspect the inside of each tube cavity or bucket. Remove any glass or other debris from the rubber cushion. 3 Ensure that the centrifuge has adequate shielding to guard against accidental flyaways. 4 Use a centrifuge only if it has a disconnect switch that deactivates the rotor when the lid is open. 5 Do not overfill a centrifuge tube to the point where the rim, cap, or cotton plug becomes wet. 6 Always keep the lid closed during operation and shut down. Do not open the lid until the rotor is completely stopped. 7 Do not brake the head rotation by hand. 8 Do not use aluminum foil to cap a centrifuge tube. Foil may rupture or detach. 9 When balancing the rotors, consider the tubes, buckets, adapters, inserts, and any added solution. 10 Stop the rotor and discontinue operation if you notice anything abnormal such as a noise or vibration. 11 Rotor heads, buckets, adapters, tubes, and plastic inserts must match.
