Total Count Tester
ATTENTION
The "Total Count Tester" has a maximum durability of 1
year after its date of delivery.
The cardboard disk contains a dehydrated nutrient
medium. It is activated by the sample and serves as cul-
ture medium for a number of bacteria. The number of
germs provides information on the hygienic condition of
the water.
Performing the test
•
Allow water to run out of the SPRAYVIT syringe for
about 1 minute.
•
Then take a water sample from this syringe.
Fill in water up to the upper mark on the container. To
neutralize the disinfecting agent of the water sample,
add approx. 1.5 g of fixing salt (sodium thiosulfate).
Do not touch the inside of the container or the part of
the tester to be immersed.
•
Immerse the tester in the filled container for 30 sec-
onds.
The cardboard disk with the nutrient medium will
now absorb 1ml of the water sample.
•
Remove the tester and shake off the excess water.
Empty the container completely.
•
Place the tester into the empty container for incuba-
tion: Keep either for two days at room temperature or
for 24 hours at a temperature of 35°C.
•
Then count all germs found on the surface of the tes-
ter.
If the number of germs significantly exceeds 100,
then sanitation is required (see
tion
, page 20).
