250 ml stainless-steel pressure reactor
The HNZXIB vessel holds 250 ml and is built from stainless steel for laboratory reactions that demand a leak-free static seal. It is intended for chemists and process engineers who need a small-scale high-pressure environment. The unit ships new and includes a pressure gauge and a needle valve for direct monitoring and control. Buyers who require larger reaction volumes or continuous-flow operation will need a different platform.
Gauge and needle valve enable live pressure
The bundled pressure gauge lets operators watch the internal pressure in real time without opening the vessel. The needle valve provides fine adjustment of gas inlet or venting during a run. Together they remove the need for external manifolds when running batch experiments at elevated pressure. Users who want automated data logging or remote actuation must add their own instrumentation.
Static-seal design limits rapid thermal cycling
The flat-cover, bolted flange relies on progressive symmetric tightening to maintain a seal up to 22 MPa (220 bar) and 300 °C (572 °F). External heating should not exceed 350 °C and the recommended ramp rate is 5 °C per minute for both heating and cooling. This makes the reactor unsuitable for processes that require faster temperature swings or frequent opening while hot.

Questions about this item
How often do the gasket or tapered sealing surfaces need replacement on this 250 ml reactor?
The sealing port uses a gasket or line-contact tapered surface that is compressed by the main bolts; inspect these surfaces each time the vessel is opened and replace the gasket if any deformation or wear is visible.
What is the first operating limit reached during prolonged heating at the maximum 5 °C/min rate?
The vessel is rated for 300 °C and 22 MPa (220 bar); the safety pressure of 22 MPa will be reached before the 300 °C temperature ceiling if the reaction generates sufficient vapour pressure.
How hot does the stainless-steel body get during continuous operation at 300 °C?
The reactor body is designed for 300 °C (572 °F) service; external heating should not exceed 350 °C, so the vessel wall will approach the set-point temperature during all-day runs.
