Use of the Micro Kjeldahl
Applicable methods for nitrogen determination as outlined by the A.O.A.C. or other technical
procedures involved with Protein (Nitrogen) determination by the Kjeldahl method, are to be
referred to in all cases.
The infinite heat control in the digestor uses a bi-metallic element to proportion the on and off time
of the heating element. In the “high” position, the heater is on 100% of the time and in the “low”
position the heater is on 20% of the time.
A digestion of extremely small samples may require less heat than available from the lowest
control setting. In that event, a voltage reducing device should be used to reduce the power input
to the apparatus.
CAUTION: DO NOT boil flasks dry. Breakage of the flask may occur.
