Stainless steel 300ml high pressure reactor with gauge and needle valve

HNZXIB

HNZXIB 0.3L High Pressure Reactor with Pressure Gauge and Needle Valve, 300ml laboratory supply

SKU CH-AM1C-3PWE8

A 300 ml stainless-steel high-pressure reactor rated for 22 MPa and 300 °C with a pressure gauge and needle valve for leak-free chemical reactions

  • Total capacity300ml
  • Product typePressure Reactor
  • 300 ml capacity fits small-scale synthesis
  • 22 MPa (220 bar) rating handles demanding reactions
  • 300 °C (572 °F) operating temperature enables high-heat chemistry
  • Stainless-steel body resists corrosion and ensures durability
  • Static-seal design with needle valve prevents leakage during operation

0.3 L High-Pressure Reactor

This 300 ml stainless-steel reactor is built for small-scale chemical synthesis under static-seal, no-leakage conditions. It targets laboratory researchers who need a compact vessel for high-pressure experiments up to 22 Mpa.

Replaces open-vessel setups

The unit upgrades from atmospheric glassware when reactions demand 220 Bar and temperatures reaching 300 °C (572 °F). The jump is worth it for processes that require sealed containment and precise thermal control beyond what open systems can safely deliver.

Static-seal pressure limit

The flat-plate lid and bolted flange rely on symmetrical tightening of a gasket or metal-to-metal line contact to hold pressure. Safe operation requires gradual, even torque and natural cooling to room temperature before opening; exceeding 350 °C external heating or rapid thermal cycling risks seal failure.

Questions about this item

What bolt pattern secures the 300ml reactor cover to the flange?

The cover is a flat plate connected to the flange by main bolts and nuts; tighten them symmetrically in several gradual passes with equal force to prevent the cover from tilting and to achieve a leak-free seal.

What is the correct tightening sequence for the main bolts on this high-pressure reactor?

After loading the vessel, tighten the main bolts and nuts symmetrically in multiple gradual steps using equal force so the flat cover seats evenly against the gasket or tapered line-contact seal without tilting.

How often should the gasket on this 300ml stainless-steel reactor be replaced?

The reactor uses a gasket or tapered line-contact seal made from materials such as PTFE, copper or asbestos; inspect it after each run and replace it whenever it shows deformation, cracking or loss of sealing performance.
