VACUUM
The ThermoVac is capable of pulling a maximum vacuum of 28.4 inches of
mercury. If the VACUUM switch is pushed to the right the vacuum pump
will turn on and remain on for approximately 5 minutes (recommended time
for degassing samples), then the pump will shut off. If you desire to remove
the vacuum before the preset time you must turn off the main power switch (located at the rear of
the instrument). When the switch is pushed to the left the vacuum pump will remain on till it is
manually turned off (either by pushing the VACUUM switch to its middle,
OFF
, position or by
turning off the main power switch).
TEMPERATURE
Use this dial to set the temperature, in °C, for thermostatting the sample chamber. The rightmost
digit sets the temperature value in tenths of a degree. Typically, ITC samples are thermostatted to
a temperature that is below the desired run temperature for the sample. This should also allow for
any temperature increase that may occur during the transfer of solution from the ThermoVac to
the ITC cells or syringe.
SAMPLE TEMPERATURE
Displays the current temperature of the sample chamber.
