8.1
CLEANING INSTRUCTION
Liquid waste is potentially biologically hazardous. Always wear gloves if handling those materials. Do not
touch parts of the device other than those specified. Consult the laboratory protocol for handling biohazardous
materials.
Take care that no liquid enters the device! There is no protection against penetrating of liquids
(Code IP X0). Check from time to time that the tubing and the connections are leakproof.
The
flow-through system
of the Photometer
5010
has to be washed with dist. water regularly before and after
measuring 2 – 3 times. Depending on sample material and reagent, and
always
at the end of a working day, the
Photometer
5010
has to be cleaned additionally with a phosphate-free detergent, e.g. with approx. 5ml of
Biogent-A (REF 5010-024), and afterwards rinsed with 5ml distilled water.
Persistent residues are to be removed with a combined alkaline-acid treatment. The following procedure is
advised step by step:
1. 5 x wash with NaOH 1 N
2. 5 x rinse with dist. water
3. 5 x wash with HCl 0.5 N
4. 5 x rinse with dist. water
If the system is contaminated severely, it may alternatively be cleaned with hypochlorite. The following proce-
dure is advised step by step:
1. 5 x rinse with dist. water
2. 2 – 3 x wash with hypochlorite (1:20 diluted solution) or ISE Cleaning Solution,
undiluted, let it possibly affect up to 20 minutes
3. 5-10 x rinse with dist. water
For device cleaning and surface decontamination purposes use commercial decontaminating solution which are
usually available in clinical chemistry laboratories like Mikrozid
®
AF Liquid, Bacillol
®
plus, 3 % Kohrsolin
®
or
similar solutions. Switch off the device and disconnect it from the mains voltage. Then clean the device with soft
cloth and decontaminating solution.
Empty the drain tank at the end of daily measurement, or whenever filled.
