These High Pressure/High Temperature Vessels have a 1-inch inside diameter and offer volumes of 25 or 75 mL. These vessels are closed with an alloy steel screw cap which includes six cap screws to develop the sealing force on a flat, flexible graphite gasket. Interchangeable PTFE gaskets are also available for users who need the high pressure capabilities provided by these vessels, but who do not need to operate above 350 °C. Maximum pressure drops quickly at temperatures above 350 °C to a rating of 1850 psi (125 bar) at 538 °C. These vessels are available in all of the standard materials currently offered by Parr, although some of these materials will limit the maximum pressures and temperatures available.
The head of these vessels can only accommodate one opening. It is designed to accept the 4310A Gage Block Assembly which can be furnished with or without a thermocouple. Parr offers the 4921 Bench Top Ceramic Fiber heater for use with the 75 mL, 4740 Vessel only. The smaller 25 mL Vessels are generally heated in an oven, bath, furnace or similar general purpose heater (not available from Parr).
With Flexible Graphite Flat Gasket: 500-538 °C
