c. After the rotor stops spinning, the cover unlocks and
the lid locked indicator is turned off. The display
reverts to last set parameters.
d. Open the cover and remove samples.
GENERAL: During the run, display shows actual parameters.
To check set parameters, press
View
button and
Select
button. The display will revert temporarily to the set points for
approximately 5 seconds.
Drying Rate
Thermal energy can be applied to the concentrator chamber
to counteract the cooling effect of evaporation, maintain the
samples in the liquid state, and accelerate the concentration
run. Select the highest drying rate if you desire accelerated
drying. To ensure against over drying of samples, and
possible denaturing, it is recommended that the “Heater”
timer be set for only a portion of the total run time (e.g., 50%-
75% of total run time).
Exporting Live Run Data
The unit is equipped with a USB port to enable
communication with an external computer. The USB port is
located on the rear panel of the unit and is connected to a
computer via a standard USB type A to B cable.
Figure 2. USB Port location
When a run is ongoing, the unit exports the following
information via the USB port every minute.
•
The live temperature applied to the samples chamber
•
The remaining heat time for the run (“CCC” indicates
continuous heating)
•
The remaining or elapsed run time, depending on the run
type (manual or automatic)
The data are sent at a fixed baud rate of 115200 and are
comma-separated as shown in the format:
<temperature>,
<heat time>, <run time>.
•
The temperature is represented as a 2-digit integer in °C
•
The heat time is expressed as a 3-digit integer in minutes
(or “CCC” for continuous heating)
•
The runtime is expressed as a 3-digit integer in minutes.
Note:
The following section details the step-by-step
procedures for configuring Microsoft
®
HyperTerminal running
on a host computer using Windows

4. Connect to the virtual COM port that is linked with the
SpeedVac™ concentrator attached to the computer
(USB virtual com port).
5. In the “COM Port Properties” box \ “Port Settings” folder
select the following options:
Bits per second: _ 115200
Data bits: _ 8
Parity: _ None
Stop bits: _ 1
Flow control _ None
After verifying the above settings, click
OK
.
6. In the main dialog box click on
File
\
Save
