Introduction to Bomb Calorimetry
There are a number of factors which should influence a user in the selection of a calorimeter. In general, the following four areas will help define the correct calorimeter choice:
- Precision
- Workload
- Type of Analysis: including Test Method, Sample Size and Sample Characteristics
- Budget
To learn more about each of these factors please read Parr's Calorimeter Selection Criteria Tech Note 105.
Parr continues to offer the
broadest range of oxygen bomb calorimetry available.

Model 6400 Calorimeter. Designed for laboratories that require high through-put. The unit features a closed loop cooling subsystem in the calorimeter. The patented Quick Twist-Lock vessel closure design allows one operator to run up to four 6400 Calorimeters simultaneously.
Model 6300 Calorimeter. An alternative to the 6400 Calorimeter. This highly mechanized calorimeter is a cost effective system; both as a capital investment and by limiting operating costs. It is capable of running off of tap water and one operator can run up to four 6300 Calorimeters simultaneously.
Model 6200 Calorimeter. Featuring a removable bomb and bucket design, the 6200 is our most popular calorimeter. It is a good choice for high precision quality control work and for research and development. Multiple bomb choices are available, expanding its functionality.
Model 6100 Compensated Calorimeter. The 6100 takes advantage of the real time, continuously corrected method originally developed by Parr Instrument Company. While not an isoperibol method, its real time correction achieves nearly equal results. This feature, along with a reasonable price, make it attractive for waste and refuse disposal work and student instruction.
Model 1341 Plain Jacket Calorimeter. A reliable calorimeter, the 1341 can be used for the same broad range of solid and liquid combustible samples. Its modest cost and simple design make the model suitable for low throughput and minimal precision work such as sample screening and student instruction. (Bulletin 1341MB)
Model 6725 Semimicro Calorimeter. A compact, static jacket, calorimeter designed specifically for measuring the heat produced by the combustion of small samples. (Bulletin 6700MB)
Model 6755 Solution Calorimeter. For laboratories who wish to measure enthalpy changes produced by chemical reactions in solution. (Bulletin 6700MB)
