The 1341 Plain Jacket Calorimeter is the current version of the static jacket, oxygen bomb calorimeter that Professor Parr developed over 100 years ago. It is a reliable calorimeter that can be used for the same broad range of solid and liquid combustible samples as the 6000 series calorimeters. Its modest cost and simple design make the model suitable for low throughput and minimal precision work such as sample screening and student instruction.
Static Jacket
Although commonly called a plain calorimeter because of its simple design, technically this is a static jacket instrument which operates at or near room temperature with no provision for controlling the jacket temperature. Compensation for any heat loss (or gain) during a test is made by applying a correction computed from heat leak measurements taken before or after each test. Good repeatability can be obtained with the 1341 Calorimeter provided that the temperature rise and heat leak corrections are measured and applied carefully.
Laboratory Requirements
The calorimeter requires a source of 99.5% oxygen, deionised water and an ignition unit for operation.
1341 Plain Calorimeter
The 1341 Plain Calorimeter includes the following components:
- 1341 Calorimeter
- Oxygen Bomb
- Oval Bucket
- Oxygen Fill Connection
- 6775 Digital Thermometer
- 6008 Bomb Maintenance Kit
6775 Digital Thermometer
The 6775 Digital Thermometer provides digital precision and reliability for temp- erature measurements. The thermometer has a working range of 10°C to 40°C and a resolution of 0.001°C. The readout is displayed on a clear LCD screen. In addition to displaying temperature, the thermometer includes a timer that can be used to manually record the time intervals of specific temperature readings. The thermometer uses high capacity lithium batteries which provide approximately 200 hours of operation.
Designed for use with the Parr 1341 Plain Jacket Calorimeter, the 6775 is a replacement for the 1604 and 1623 liquid-in-glass thermometers.
