The syringe-degasifier is designed to withdraw air from fresh and separated milk.
The cap is removed from the syringe. 30 cm3 of milk and 10 cm3 of air is taken into the syringe, and the bottom edge of the syringe piston should be right at the «40» mark located on the housing of the syringe. The syringe is closed with a cap, the rod of the syringe is extracted up to the end of the stops located at the syringe rod. The stops should fix the syringe rod in an immovable position. Milk is stirred by lightly rocking the syringe for 30 seconds. Then the cap is removed, the stops are pressed to the syringe rod, the degassed milk is poured into a container of 50−100 cm3 capacity.
On removal of the cap, a light clap should be heard, which indicates vacuum presence inside the syringe. Lack of the clap means the sealing is broken, and no milk degasation is possible. Restore the sealing (check the syringe rod for leakage, ensure the syringe is tightly closed with the cap, check the integrity of the housing), and repeat degasation of the sample.
