c)
An important principal of the Covaris Focused-ultrasonicator is isothermal temperature control. Your system automatically adjusts the
water temperature, as necessary, to match the method temperature set point once a method is selected. Water Temperature status
will turn green when temperature is within the Min and Max limits (by default 5 degrees above or below the set point). The default
set point (in the absence of a selected method) is 20 ºC.
Bath cool down from room temperature to below 10 degrees takes about 30 minutes. Once a method starts, if the
bath temperature rises beyond the user specified limit, your system finishes the current row being treated, pauses treatment, and
automatically resumes when the temperature is back within limits, with no operator intervention required.
d)
Properly degassed water is important for efficient transfer of acoustic energy from the instrument’s transducer to the sample being
treated. If water is detected in the bath, the degassing pump is automatically turned on when SonoLab is started. The pump should
be allowed to run until the Degas indicator on the Status Screen turns green (60 minutes) prior to an acoustic treatment. The degas
pump can be manually turned on and off from the Water Works pane. See additional information below in section Other Controls on
the Home Screen.
e)
When the “Run” button is clicked to start the method, SonoLab checks that the bath water is at an appropriate level for the
consumables employed in the method. If the water level is incorrect, the method is paused and a message to adjust the water level
is presented.
The remaining conditions, along with their related status, are displayed in the Instrument Status panel. Click the “
System Status
” button
to display the Instrument Status panel. An acceptable condition is indicated by a green check mark in the Status box.
If a condition is not acceptable, the status will show
X
.
If any of the items other than “Water Level” and “Temperature within Limits” in the Status list display
X
, a red
X
will also be displayed in
the System Status button, as shown below. Water level and temperature will be adjusted as necessary once a specific method is started.
