Food Calorimeter Unit

The food calorimeter offers superior method of measuring the energy in foodstuff, compared to burning it under boiling tube of water. The enclosed vessel and copper tube ensure that more of the food's energy is used to heat up the water, and less heat is lost to the environment, increasing the accuracy of the experiment.
The unit comprises glass jacket with bell jar inside. spiral copper tube draws air through the bell jar, in which food is burning, transferring more of the heat to the water. The lid has holes for thermometer and stirrer.
The base unit (BI180105) has clips to hold the calorimeter unit securely, crucible holder, and posts for replaceable ignition coil. The bottom of the base has 4 mm sockets for connecting power supply to the ignition coil.
A sample of food is placed in the crucible, the calorimeter unit placed over the top, and filled with water. The power to the ignition coil is turned on, and the food ignited. The temperature of the water is recorded, and the energy released can be calculated from the temperature change. To increase accuracy further, the calorimeter can be calibrated using spirit with known energy density.
Also required: a 12 V power supply, 4 mm plug leads, a 0.1 g resolution balance and crucible.
Please note that the calorimeter unit and base are sold separately, and both are required.
