8.B. Cleaning the Hardware
If the plungers are inadvertently omitted during a run or placed in the wrong starting position, the machine may
go through a run with the magnetic rods unprotected. If this happens, the magnetic rod assembly needs to be
removed for cleaning.
1.
To remove the hardware, see Section 7.A.
2.
To clean the magnetic rod assembly, wipe with a damp, soft cloth. You also can wipe the assembly with 70%
ethanol. Removal of paramagnetic particles from the magnetic rod assembly will require multiple wipes. Use
a damp towel wrapped around a magnet to help remove paramagnetic particles.
3.
If the magnetic rod assembly cannot be cleaned, please contact Promega for assistance.
4.
Replace the magnetic rod assembly, and firmly tighten the three thumbscrews.
5.
Ensure that the hardware mode displayed in the Home screen matches the hardware that is installed in the
instrument.
8.C. Dealing with Spills
Wipe up any spills immediately. If the reagent spills in the instrument, wipe up visible material with a cloth. Dried
material should be wiped up with a wet towel. Note that the reagents contain hazardous materials; therefore
dispose of towels according to your institutional guidelines. Wipe well once visible material is removed.
In case of spills in the instrument where there is a potential biohazard, wipe up the spill with towels and wash the
spill area with a detergent solution such as Steris
towels used according to your institutional guidelines for biohazardous waste.
UV-treat the instrument.
!
Important. Bleach reacts with guanidine thiocyanate and should not be added to any sample waste containing
lysis solutions.
8.D. Decontamination Using the UV Lamp
UV radiation is useful in decontamination due to its ability to inactivate biological molecules. The Maxwell
MDx Instrument is equipped with a UV lamp that can be used to treat the interior of the instrument with UV light,
after cleaning, to help with decontamination. UV treatment is not a substitute for cleaning. Using the UV lamp
treatment alone may not provide sufficient decontamination.
To turn on the UV lamp manually, navigate to the Home screen, and select the Setup option. In the Maxwell
16 Configuration screen, select Configuration. In the Configuration screen, select UV Setup. In the UV
Settings screen, select the option to switch on during startup and set the amount of time you would like to run the
lamp. The recommended setting is at least 60 minutes when cleaning up after a spill. The maximum setting is 600
minutes. Return to the Configuration screen and select UV On. The UV lamp will turn on and remain lit for the
time set. Once the instrument has been UV-treated, the UV time may be reset by navigating to the UV Settings
screen and resetting the UV treatment time.
