Applicable Rotors - Thermo Scientific Sorvall MTX 150 Instruction Manual

Tubes
Figure 2-2. Balancing tubes/bottles containing a sample solution
Depending on the type of tube or rotor combined with this machine, an excessively low liquid level
may limit the speed or crush the tube.
• When sealed tubes are used, fill the tubes with liquid to the full level.

Applicable rotors

For the Sorvall MTX 150 micro-ultracentrifuge you can only use automatic securing rotors shown
below. These rotors can be installed by merely placing it on the drive shaft in the rotor chamber.
Screw-type rotors, also shown below, are inapplicable to the Sorvall MTX 150 micro-ultracentrifuge.

Within 5 mm
CAUTION Do not run the micro-ultracentrifuge in an extremely imbalance condition.
This might cause a mechanical failure. When balancing tubes or bottles by eye, alarm
message "IMBALANCE" might appear. Balance tubes or bottles more accurately again if
alarm message "IMBALANCE" appears.
CAUTION
1. Before using a rotor, read the rotor instruction manual carefully.
2. Do not use any corroded, scratched, cracked, or otherwise damaged rotor or bucket.
Before operation, always check if there is no corrosion and damage on the rotor surface.
3. Before running a swing rotor, make sure that each bucket is hooked on a pin securely.
Poor setting might seriously damage the instrument. Even though all of them are not
used, make sure to install all buckets at any time. Make sure that all the rotor buckets are
of the same type.
4. Some tubes and adapters are inapplicable at the maximum speed of the rotor. Refer to
the rotor instruction manual carefully.
5. The S58A rotor, S55A rotor, and S50A rotor can handle sample whose mean density is
1.2 g/ml or less. Do not rotate this rotor at its maximum speed when using a sample
whose mean density is over 1.2 g/ml. Refer to the rotor instruction manual (Part No. PN
45735) for how to limit the maximum speed when using a sample whose mean density is
over 1.2 g/ml.
For an S140AT rotor, an S100AT5 rotor, and an S50A rotor, set the
approximate meniscus level difference to within 3 mm, and for
an S110AT rotor and an S80AT3 rotor, set it to within 4 mm.
