is as close a representation as possible to the biological samples. To maintain accuracy and longevity
of the tube thermistor Thermo Hybaid recommends the following:
1. Do change the tube thermistor annually. It may be necessary to change the thermistor more often
under heavy use (e.g. frequent removal of the thermistor from the tube).
2. Do check that the mineral oil volume is the same as the reaction volume including any oil overlay.
3. Do check and replace the control tube if it is showing signs of thermal degradation.
4. Do use the same type of tube for the thermistor tube as for the biological samples.
5. Do make sure the sensor part of the thermistor probe is centrally located at the base of the tube
and is fully covered by mineral oil.
6. Don’t use aqueous solutions in the thermistor tube.
7. Don’t remove the control tube from the cap assembly by pulling the wire; gently lever the tube
from the cap.
8. Don’t kink the thermistor wire or crush the sensor part of the thermistor probe end.
9. Don’t remove the thermistor assembly from the instrument by pulling on the wire, pull from the
plug.
