5.8.2 STORAGE AND USE OF THE REAGENTS
Table 3 Recommended storage and use of reagents
E.coli reagent
4°C / 39.2 °F Dark place.
CAUTION (Solid when < 15 °C / 66,4 °F )
1 year storage when unopened.
Consumption within 3 months when opened and kept at
room temperature.
Enterococci
reagent*
4°C / 39.2 °F Dark place.
CAUTION (Solid when < 15 °C / 66,4 °F )
1 year storage when unopened.
Consumption within 3 months when opened and kept at
room temperature.
Coliform
reagent*
4°C / 39.2 °F Dark place
CAUTION (Solid when < 15 °C / 66,4 °F )
1 year storage when unopened
Consumption within 3 months when opened and kept at
room temperature.
TA reagent
(Total activity)
-20°C / -4 °F Dark place.
4 months storage when unopened.
Consumption within 1 to 2 months when opened and kept
at room temperature.
Buffer
-20°C / -4 °F Dark place
1 year storage when unopened
Consumption within 1 to 2 months when opened and kept
at room temperature.
* IMPORTANT!
Storage at -20°C / -4 °F is also possible for E.coli and coliform reagents. However this
might affect the solubility of MUG after thawing. In case it is kept at -20°C / -4°F,
homogenize thoroughly after thawing.
E.Coli, Enterococci and Coliform reagent can be SOLID when < 15 °C / 66,4 °F.
This will not affect the reagent and it will be liquid again after warming up above 15 °C
/ 66,4 °F.
Longer periods of storage than as described above may lead to an unstable/
nonhomogeneous solution, causing deviating results.
