Preparation of 5%
EkoWeek
working solution:
a. Use pipette to add 25 mL
EkoWeek
to glassware with 475 mL distilled
water.
b. Pour into a labeled container.
Take care this solution does not contact your eyes or skin!
Attention! Use only 5 % EkoWeek working solution as a cleaning agent.
The EkoWeek concentrate can damage your analyzer!
2.1. Clean the analyzer first as it is cleaned at the end of the working day;
Attention! Make sure that the analyzer is properly cleaned with pure water
before going on to the next item of the procedure. Mixing both cleaning
solutions- alkaline EkoDay and acid EkoWeek will result in forming “milk
stone”.
2.2. Fill the measuring mug with 5 % solution of the acid cleaner
EkoWeek
(25°- 40°C), put the analyzer in cleaning mode, set 40 cycles and press the
OK
button. When the
CLEANING
stage is over,
CLEANING END
is shown on
the display.
2.3. Take the plastic plug (for Ekomilk UltraPro both plastic plugs) with the
vinyl tube out of the holes. Insert the plunger instead of the plastic plug with
the vinyl tube.
2.4. Fill the measuring mug with clean and warm, but not hot, water (40°-
60°C).
Pull up and down the plunger several times. Remove the mug and throw
away the water. Fill the mug with clean and warm water and repeat this step
4-5 times.
2.5. Take the plunger out of the syringe. Wait until all water comes out. Insert
back slowly the plunger to the bottom.
2.6. Remove the measuring mug. Take the plunger out of the syringe again.
This time insert the rubber plug with the vinyl tube instead of the plunger.
2.7. Done
Attention!
1. Perform strictly this procedure to remove both acid cleaning solution
and milk stone from the analyzer measuring system.
2. Do not use hard water (water that contains high amounts of Ca
2+
and/
or Mg
2+
) for analyzer cleaning. For best results use distilled or deionized
water.
CALIBRATION
The Analyzer should be calibrated if the measuring accuracy for one or
more milk parameters is out of the specified limits.
