3-1-2 Rotor and Tube Preparations and Precautions
The
Sorvall WX+ Ultra
series centrifuges allow you to balance samples, by eye. The difference
between meniscus levels of opposing samples must be less than 5 mm (Fig. 3-1-2), but some rotors
are exceptions.
However, some tube and bottle may in certain rotor and sample combinations trigger an imbalance
alert. If this happens, balance the samples more accurately.
Fig. 3-1-2 Balancing samples
Note that partially filled tubes may impose speed limitations or lead to tube failure with some rotors.
Tubes or bottles must be full in the following cases:
1. When thin tubes or seal tubes are used.
2. When thick tubes are loaded in a swing rotor.
3. When a bottle is used 100,000 x g or more.
For more information on rotor and tube handling, read through the "Rotor, tube, bottle and cap
instruction manual " and the instruction manual supplied with the rotor.
