DESCRIPTION

The 4748 Vessel is the largest of all Parr acid digestion vessels. 125 mL, 250 °C, 1900 psig

It has a 125 mL, removable PTFE cup in a stainless steel body with six cap screws in the screw cap to seal the flanged PTFE cup. An expandable wave spring maintains continuous pressure on the seal during the cooling cycle when PTFE parts might otherwise relax and leak. Stirring can be provided with a magnetic stir bar. A safety rupture disc above the PTFE cup will blow out through an opening in the vessel head if pressure should accidentally reach the 3500 psi range. But for safe operation, pressures in this vessel should never exceed 1900 psi and temperatures must not exceed 250 °C. Operations should be conducted well below these limits whenever possible due to the potential destructive forces in a large vessel charge. It also is advisable to test any new procedures for safety in one of the smaller vessels before scaling up to this size. A wrench for the cap screws is furnished with the vessel. No other accessories are required
