Troubleshooting
Evaporation
»
If the evaporation is uneven between wells:
»
One or more nozzles may be clogged. Clean or replace
the nozzle manifold, see page 11 and page 20.
»
One or more nozzles may be bent. Make sure the
nozzles are aligned in straight rows. If the nozzles
cannot be aligned, contact Biotage
®
1-Point Support
™
.
»
The manifold and the well plate may be
misaligned. To align the bottom heater to the
manifold, contact Biotage
®
1-Point Support
™
.
»
If the evaporation rate is too slow:
»
Check that the gas flow is not too low; see "Determine
the Appropriate Gas Flow" on page 6.
»
Check there is no gap between the manifold and
the gas heater. Check the screws are tightened.
»
Check that the gas inlet tube is not leaking.
»
Check that the pressure regulator is set to the appropriate
range. See the technical specification in TurboVap
®
96 Dual Installation and Safety, (P/N 418002).
»
If the evaporation rate is too rapid or splashing occurs:
»
Check that the gas flow is not too high, see
"Determine the Appropriate Gas Flow" on page
6 and the technical specification in TurboVap
®
96 Dual Installation and Safety, (P/N 418002).
»
Check that the nozzles are not too close
to the surface of the samples.
»
If there is no gas flow:
»
Check that the gas supply is turned on and
that the pressure is higher than the minimum
pressure specified in TurboVap
®
96 Dual
Installation and Safety, (P/N 418002).
»
Check that the gas inlet tube is not
obstructed or damaged.
»
If the recovery of sample is low:
»
Check that the plate heater temperature is not too high,
thereby causing the solvent to boil; see "Determine the
Appropriate Plate Heater Temperature" on page 7.
»
Check that the sample is not left too long on the
plate heater after the evaporation is completed.
»
Check that the gas flow is not too high and
causing splashing; see "Determine the
Appropriate Gas Flow" on page 6.
»
Check that the gas heater temperature is not too high,
thereby causing the solvent to boil; see "Determine the
Appropriate Gas Heater Temperature" on page 7.
Gas Supply
»
If a gas leak has been detected at the gas inlet (the
N2
port):
»
Check that the gas inlet tube is securely attached.
»
Check that a gas inlet tube with the correct
outer diameter is used, i.e. 6 mm. Always use
tubing and adapters supplied by Biotage.
»
If the instrument warns for too low gas pressure or the
flow rate does not reach the expected set value:
»
Check that the pressure at the inlet (the N2 port)
meets the minimum pressure requirement specified in
TurboVap
®
96 Dual Installation and Safety, (P/N 418002).
»
Check that the provided inlet tube is used. A
longer tube may cause pressure drop.
Touch Screen
»
If the touch screen is not responding as
expected, test its calibration:
»
Press
More
in the settings view and then
Verify Screen
.
»
Draw or write on the touch screen to
verify its function and calibration.
»
If the touch screen calibration is off, calibrate it:
»
Press
More
in the settings view and
then
Calibrate Screen
.
»
Follow the instructions on the screen and then test
the calibration as described in the bullet above.
»
If the touch screen calibration wizard cannot be
accessed due to a faulty calibration, restart the system
and repeatedly open and close one of the doors during
start-up. This will open the calibration wizard.
Note:
The door only needs to be opened approximately 20
mm.
Lift
»
If there is an error message regarding a lift:
»
Restart the system. Should the error persist,
