Warning
The decontamination procedure should be performed by
authorized trained personnel in a well-ventilated room wearing
disposable gloves, protective glasses, and clothing.
▲
Decontamination should be performed in accordance with normal
laboratory procedures. Any decontamination instructions provided with
the reagents used should be followed.
It is strongly recommended to perform the complete decontamination
procedure before relocating the instrument from one laboratory to
another.
Example of decontaminants:
●
Ethanol 70%
●
Virkon™ solution 1–3%
●
Glutaraldehyde solution 4%
●
Chloramine T
●
Microcide SQ™ 1:64
●
Decon™ 90 min. 4%
Caution
If local or laboratory regulations prescribe regular
decontamination, it is not advisable to use formaldehyde, since even
small traces of formaldehyde negatively affect the enzyme being used in
EIA tests, resulting in inconsistent test results.
