1-4 Sorvall MTX 150
Functions and Actions
Display various fields.
The SPEED (RCF), TIME, and TEMP fields give the current status indicator in the top row and
the setting indicator in the bottom row. (For setting, see
• SPEED (Speed indicator)
(Top row) Displays speeds in increments of 10 rpm at lower than 5,000 rpm, and in steps of 100
rpm at 5,000 rpm or more.
(Bottom row) Sets speeds from 5,000 to maximum speed in increments of 1,000 rpm. The lower
three digits (one, ten, and one-hundred positions) display zeros.
Maximum speed: 150,000 rpm
For RCF, see "Displaying and setting RCF"
• TIME(running time indicator)
(Top row) Displays the remaining operation time. If the running time is set to HOLD, this field
displays time elapsed.
(Bottom row) Specifies a setting in the range from 1 minute to 99 hours 59 minutes in steps of
minutes and hours.
• TEMP(temperature indicator)
When the pressure in the rotor chamber equals the atmospheric pressure, the temperature of
the inside of the rotor chamber is kept at 25 °C to prevent condensation.
(Top row) Displays in steps of 0.1 °C.
(Bottom row) Sets a setting in the range from 0 °C to 40 °C in increments of 1 °C
The column is shifted from SPEED (RCF) column to RCF (SPEED) column by pressing this
button.
The Acceleration rate and Deceleration rate are set by pressing this button.
• ACCEL(acceleration mode indicator)
Displays acceleration modes 1 through 9.
• DECEL(deceleration mode indicator)
Displays deceleration modes 1 through 9, along with free coast (F).
ROTOR CATALOG is displayed by pressing this button and you can select the desired rotor.
• Press this button to turn the vacuum pump on or off. When the vacuum pump is turned off,
the pressure in the rotor chamber will change to equal the atmospheric pressure. (While the
rotor is rotating, you can not turn off the vacuum pump.)
• Temperature control starts as soon as the vacuum pump is turned on.
Displays the following four stages according to the vacuum of the rotor chamber.
(1) Atmospheric state.
The vacuum pump is not activated.
(2) Low vacuum. The rotor waits at 5,000 rpm until the vacuum
reaches an intermediate level.
(3) Intermediate vacuum.
(4) High vacuum.
Starts rotor rotation. If VACUUM is off, pressing this button activates the vacuum pump and
starts temperature control.

on page 2-41.
NOTE: If the sample is sensitive to a
temperature rise, do not press the START
button until the chamber is at a high
vacuum level
on page 2-5.)
