General InformationSpecificationProduct Photos Parr offers a number of different reactors in the 4570 and 4580 Series in a variety of sizes and with different mountings for operating pressures to 5000 psi (345 bar) and temperatures to 500 °C 4581 – 4582 Reactors These 1 gallon (3.75 L) and 1.5 gallon (5.5 L) reactors are designed…
General InfoProduct PhotosSpecification These 4550 Reactors extend the size range of the 4530 Series to 1 and 2 gallon (3.75 and 7.5 liter) sizes, providing excellent facilities for pilot plant studies. They can be furnished with either a self-sealing O-ring closure for working temperatures up to 225 °C, or with a flat, PTFE gasket for…
General InfoProduct PhotosSpecification The Model 4555 and 4557 Reactors with their 5 gallon (18.75 L) capacity are the largest stirred reactors offered by Parr. The 4556 and 4558 Models are similar units with a 10 liter (2.6 gal) volume which falls between the larger 5 gallon design and the smaller 1 and 2 gallon models…
PARR 6400 Automatic Isoperibol Calorimeter Designed for laboratories that require high through-put, the 6400 Automatic Isoperibol Calorimeter features a closed loop cooling subsystem and the highest automation in a calorimeter. The patented Quick Twist-Lock vessel closure design allows one operator to run up to four 6400 Calorimeters simultaneously. The 6400 Automatic Isoperibol Calorimeter represents the…
Model 6200 is a microprocessor controlled, isoperibol oxygen bomb calorimeter which is widely used for both routine and occasional calorific tests. It uses the time-tested Parr 1108 style oxygen bomb and oval bucket in a compact calorimeter, producing reliable results with good repeatability, but differing from the 6400 Model in that the bomb and bucket both must be removed from the calorimeter and refilled manually for each test, thereby requiring more of the operator’s time than the automatic and semi-automatic models.
PARR 6100 Compensated Jacket Calorimeter The Parr 6100 Compensated Calorimeter takes advantage of the real time, continuously corrected method originally developed by Parr Instrument Company. This real time correction can produce superior results. This feature will make it attractive for coal testing, waste and refuse disposal work, and other sample testing.

PARR – 1341 Plain Jacket Calorimeter The 1341 Calorimeter is an improved version of a plain, static jacket, oxygen bomb calorimeter that has been made by Parr for more than eighty years. It is a reliable calorimeter that can be used for the same broad range of solid and liquid combustible samples as the 6000 Series.…
General InfoSpecificationProduct Photos These are the largest of the Parr Reactors that can be handled on a bench top. They can be furnished with either a self-sealing, O-ring closure for working temperatures up to 225 °C or with a flat, PTFE gasket for higher temperatures to 350 °C. Both fixed head and moveable vessel designs…

They are also available in high pressure versions. Reactors Configured for Polymer Studies. The floor stand reactors in this series are mounted on a sturdy stand which will accommodate larger stirrer drive motors…
General InfoProduct PhotosSpecification This series of stirred reactors has been designed for users who need higher operating pressures than the 2000 to 3000 psi offered by the General Purpose Reactors, but do not require the high operating temperatures provided by the Series 4570 High Pressure, High Temperature Reactors. These reactors offer working pressures to 5000…
