Model 1108 Oxygen Combustion Vessel

1108 Oxygen Combustion Vessel

1108 Oxygen Combustion Vessel

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.

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.

An oxygen filling system and other accessories for the 1108 Vessels can be ordered or a vessel complete with all necessary accessories can be obtained by ordering the 1901 Oxygen Vessel Apparatus.


Model 1108CL Chlorine-Resistant Oxygen Combustion Vessel

Parr also offers a 1108CL Vessel that is the same as the 1108 model, but with a head and cylinder made of an alloy with superior corrosion resistance to the free chlorine and halogen acids released when burning halogenated samples. Users who intend to test waste materials and combustible solvents are urged to select the 1108CL Vessel instead of 1108 for its longer service life under extreme corrosive conditions. Vessel maintenance is also improved. In most cases 1108CL Vessels returned to the factory for scheduled maintenance can be restored to optimum finish simply by repolishing instead of having to rebore the cylinder to remove pits. The 1108CL Vessel may be purchased separately or it can be substituted for the standard 1108 Vessel in any Parr calorimeter or combustion apparatus.
