Acceleration and deceleration curves can be varied in three
steps according to the type of sample and experimental
conditions.
Acceleration and/or deceleration commencement speed can
be selected for the sample easy to stir.
Density gradient method is also possible.

■ Safety pursued
• 7780 conforms to International safety standard IEC 61010-2-
020.
• The various alarm detector sensors secure operation. When
the alarm is detected, the operation stops.
• Safety is increased by a rotor setup condition sensor that
detects whether or not the rotor is properly set on the driver
shaft. (Patent pending)
shaft. (Patent pending)
• Automatic rotor identification. (Patented, Patent pending)
Rotor type is automatically identified.
■ Sample temperature kept at 4°C
(At the ambient temperature of 25°C. Please refer to the rotor.)
■ Design incorporates friendliness to the
global environment and recycling
A limited amount of plastic is used to reduce the load on the
environment.
