6510 Water Handling System Operating Instruction Manual
- 4 -
Description
The system consists of a 20 liter, temperature controlled, tank with a built in circulating
pump, an attached glass delivery pipet and provision for continuous filtration of all water
in the system. This is a closed circuit system in which water is re-used continuously.
When the 6510 System is used with a 6200 Calorimeter, water from the tank is
delivered to the temperature control manifold at the rear of the calorimeter and returned
in a closed loop, thereby maintaining a constant temperature in the calorimeter.
The water handling system can be used to supply water not only to the calorimeter
jacket but also to the bucket through an attached delivery pipet. The choice of oxygen
bomb size will dictate the pipet choice as follows:
Oxygen Bomb Pipet Volume Pipet Part Number Support Assembly
1108 2000 mL 167HW A335HW
1104 1850 mL 167HW2 A335HW
1109 450 mL 167HW3 A335HW2
A maximum of two pipets may be installed on the water handler. Only one pipet may be
filling the bucket at any one time.
Temperature controlled water flows continuously through the glass delivery pipet and
back to the tank to maintain a constant water temperature in the pipet for filling the
calorimeter bucket with repeatable volumes. Flow through the pipet stops when the
stopcock is opened to fill the calorimeter bucket. The pipet refills automatically when
the stopcock is turned back to a closed position. At the end of each test, the user will
empty the bucket water into the reservoir where it is released slowly into the tank so as
not to cause a sudden change in temperature.
NOTE: Do not leave the stopcock dry as the Teflon will seize in the glass.
Incorporated in the system is a solid-state water chiller that is capable of removing and
dissipating the heat in the returned bucket water produced during calorimetric testing,
thus maintaining the water at a constant temperature for repeatable test temperatures.
Required Accessories and Utilities
Approximately 15 L of water with a total hardness of less than 85 ppm is required for
filling the tank of the system.
