The Series 4600, 1L Vessels are the largest of the Parr vessels that can be handled on a bench top.
- Moveable or fixed head mounting style
- Bench top stand
- 131 bar (1900 psi) maximum pressure (MAWP)
- Split-ring (6 Compression bolts for flat gasket, no compression bolts for O-ring) closure
- 3,175 mm Male NPT
- 114,3 mm Pressure gage
These reactors are available with an FKM O-ring seal for operating temperatures to 225 °C, and FFKM O-ring for temperatures to 300 °C, or with a flat, PTFE gasket for operating temperatures up to 350 °C maximum. An optional HP (High Pressure) flat gasket version has been added for maximum allowable working pressure of 200 bar (2900 psi) at 350 °C. Both fixed head and moveable vessel designs are available.
With their larger diameter, these mid-size reactors have sufficient space for special modifications, such as an internal cooling coil, bottom drain valve (not on 2 L bench top), ball valve for a solids charging port, catalyst addition devices, condensers, electrical feed-throughs and more.
