תיאור
The Series 4680 High Pressure/High Temperature Vessels are available in either a 1.0 L or 1.8 L capacity. The maximum temperature for these vessels is 600 °C and at that temperature can be run at a maximum pressure of 4200 psi (290 bar). Or, run these vessels at 350 °C and obtain a maximum pressure of 6000 psi (410 bar). A Split Ring closure with 12 Compression Bolts secures the head which allows a maximum of 8 openings. The Series 4680 Vessels can be configured with either a fixed head on a floor stand or as a moveable head vessel on a moveable cart. An optional pneumatic lift is available on the floor stand model.
