Chapter 5 Care and Maintenance
5.1 Instrument Maintenance
In order to ensure the reliability of daily operations, please clean up the dust in time to prevent
liquid leakage. Do not use abrasive cleaners, as they may damage the paint surface.
It is recommended that you clean the surface of the instrument regularly to maintain its good
appearance. Wipe with a soft cloth dampened with warm water and neutral detergent. If necessary,
clean the outer surface of the instrument and the turntable with clean low-pressure compressed air, or a
cloth dampened with water or a mild detergent.
Although Purifier HT is made of high-quality materials, you must remove the spilled salt
solution, chemical solvent, acid or alkaline solution from the surface immediately to prevent damage
to the instrument.
Caution
The painted surface can be cleaned with most laboratory cleaners. Do not
expose the surface to concentrated acid or ethanol for a long time to avoid damage.
The display, plastic door and surface can be cleaned with mild laboratory cleaners or
alcohol.
Waning
If any surface is contaminated with biologically hazardous materials, it should
be cleaned immediately with a mild disinfectant solution. Do not autoclave any part of
the instrument.
5.2 Cleaning
Keep the surface of the platform clean to prevent dust and dirt from entering the instrument. At
least once a week, clean the surface of the turntable with a soft cloth or paper towel dampened with
ethanol, mild detergent (SDS, sodium lauryl sulfate) or soap solution. If contaminated reagent is
spilled out on the turntable, clean it with a cloth dampened with ethanol or mild detergent.
5.3 Magnetic Rods Cleaning
If necessary, soak the magnetic rods in alcohol, mild detergent (SDS) or soap solution, and
then wipe the magnetic rods finally.
5.4 Waste disposal
Follow the specific regulations of laboratories and the country for handling biological waste.
For the disposal of contaminants, please refer to the relevant local regulations.
Warning
The sample may be potentially contaminated. Dispose of disposable deep-
well plates, parafilm, magnetic tip comb, disposable gloves, syringes, and disposable
pipette tips as biohazardous waste.
5.5 Decontamination Procedure
If you have spilled out contaminant reagents, please perform a decontamination procedure.
Warning
The decontamination procedure should be carried out by authorized
trained personnel in a well-ventilated room, wearing disposable gloves, protective
glasses and clothing.
Follow regular laboratory procedures for decontamination. The decontamination instructions
provided with the reagents used should be followed. It is strongly recommended to perform a
complete decontamination procedure before transferring the instrument from one laboratory to
another, or before sending it to a repair service department.
