or call us at 1-800-727-0467
The 1108 Vessel is the standard, 350 mL, general purpose vessel which is widely used in all Parr 6100, 6200 and 1341 Calorimeters, and in the 1901 Oxygen Vessel Apparatus. It will safely burn samples liberating up to a maximum of 8000 calories per charge, using oxygen charging pressures up to 40 atm.
This vessel features an automatic inlet check valve and an adjustable needle valve for controlled release of residual gasses following combustion. They are intended for samples ranging from 0.6 to 1.2 g with a maximum energy release of 8000 calories per charge. The 1108B has a larger screw cap and is rated for a maximum release of 10,000 calories. The 1108P and 1108BP Vessel features a semi-permanent heating wire and cotton thread. When contact is made through the heating wire, the thread will burn, drop into the sample cup and ignite the sample.
The standard 1108 Vessel is made of a special niobium stabilized stainless steel selected for its excellent resistance to the mixed nitric and sulfuric acids produced in a vessel combustion. This is a superior alloy which is suitable for most combustion tests, yet neither it nor any other stainless steel will resist the corrosive atmosphere produced when burning samples containing halogen compounds. For these applications Parr offers the 1108CL Vessel described below. All 1108 Vessels are available in Alloy 20 and Alloy G30.
