1. Adding Sulphuric Acid
1.1. Ensure the Bulb Screw is closed tightly.
1.2. Place the Butyrometer in the stand with Bulb facing downwards.
1.3. Pour 10 ml of sulphuric acid in the body.
1.4. Gently tap the Butyrometer on the stand in order to allow a small part of the acid
to flow into the scale and the Bulb.
2. Pipetting the milk
2.1. Carefully turn the bottle with the milk specimen upside down three or four times.
2.2. Then immediately pipette 10.75 ml of milk into the Butyrometer.
(Laying the milk carefully on top of the acid)
3. Adding Amyl Alcohol
3.1. Add 1 ml of amyl alcohol onto the milk.
Two Mode Function: Centrifugation Mode and Read Off Mode
Safety Butyrometer
5. Shaking the Butyrometer
5.1. Shake the Butyrometer vigorously until the liquids are thoroughly mixed.
Note: When the liquids are mixed, a considerable amount of heat is given off.
4. Locking the Butyrometer
4.1. Tighten the Body Screw carefully.
Important: turn the screw up to the stop! (Centrifugation-Mode).
4.2. Press the stabilizer on the Body Screw.
6. Centrifugation
6.1. Immediately after the mixture has been shaken and turned upside down a few
times, the Butyrometers (at least 2 Butyrometers in order to avoid unbalances)
still hot and with bulb pointing upwards, are placed in buckets inside the heated
FUNKE-GERBER centrifuge.
6.2. Centrifuge settings: Time: 5 minutes
Centrifugal force: 350 g +/- 50 g Temperature: <60°C
6.3. Start Centrifuge.
7. . Warming up
7.1. After centrifugation remove the Butyrometers from the centrifuge, taking care not
to tilt them. Place the Butyrometers with bulb pointing upwards for 5 minutes in
a water bath, which is heated to a temperature of 65°C +/- 2 K.
The stabilizer can be removed before.
8. Read out measurement results
8.1. After removing the butyrometer from the water bath, hold it vertically at the height
where the meniscus of the column of fat is at eye level.
8.2. By using the screw below you can adjust on zero the demarcation line between
the residual mixture and the fat column and read out at the lowest point of the
meniscus. (Read Off Mode).
turn the screw up to the stop! (Centrifugation-Mode).
the residual mixture and the fat column and read out at the lowest point of the
meniscus. (Read Off Mode).
