3.3 Cleaning and Decontamination
3.3.1 Cleaning the System
The DYNEX Technologies DSX Automated ELISA System is constructed from materials
that are resistant to chemical attack.
Spills should be cleaned up as soon as possible. The service engineer should clean and
decontaminate the system before servicing it.
WARNING: MAKE CERTAIN THAT THE POWER CABLE IS
DISCONNECTED BEFORE CLEANING THE INSTRUMENT.
To Clean the System:
Clean all external surfaces with a cloth moistened with a mild laboratory detergent. If
necessary dilute the detergent according to the manufacturer's instructions before
using.
Note: If particulate matter is observed in the Wash Bottle, the wash solution
should be discarded at once.
To Decontaminate the System:
Wipe all surfaces with a cloth moistened with a cleaner such as iDecon Detergent
disinfectant or a 70 % (by volume) solution of alcohol.
Note: If bleach is used, remove residual bleach from surfaces with a cloth
moistened with deionized water. Residual bleach fumes may affect the
results of ELISA assays.
If the system will not be used for a period of time, the system should be flushed with
de-ionized water so that buffers and/or reagents are not deposited on the wash head or
other components of the system. The dispense tubing should be removed from the
pinch valves to prevent permanent compression of the tubing.
If dispense or aspiration tips become clogged, use the wires supplied with the system
to remove any particulate matter from them.
If a system is returned to a DYNEX Technologies facility, the customer must
decontaminate the system before shipment and a decontamination certificate must be
submitted with the unit (see Cleaning and Decontamination on page 3-4).
