  • Operates up to 240 °C with 220 °C safety limit
  • Heating and cooling rates capped at 5 °C/min for safe control

250 ml Hydrothermal Synthesis Reactor

This 250 ml hydrothermal synthesis reactor provides a sealed vessel for high-temperature, high-pressure digestion and synthesis. It is intended for laboratory staff and researchers who need a compact autoclave for sample preparation in materials, environmental or analytical work.

Thermal limits and safe operation

The reactor is rated for a maximum temperature of 240 °C with a security limit of 220 °C. Heating and cooling rates must stay below 5 °C per minute, and the fill level should not exceed 80 % of the 250 ml capacity to maintain safe pressure containment.

Non-magnetic steel body with PTFE liner

The outer shell uses non-magnetic 0Cr18Ni9Ti stainless steel for corrosion resistance and structural strength. A Teflon inner lining gives acid and alkali resistance while protecting the metal from direct chemical attack. The vessel ships in a wooden case and includes a one-year warranty.

Questions about this item

How do I install the PTFE liner inside the 0Cr18Ni9Ti stainless-steel autoclave body and which step do users most often miss?

Place the PTFE liner into the vessel, add reactants up to the 80 % fill limit, seat the lid gasket, then torque the bolts evenly in a cross pattern; the step most often missed is confirming the liner sits flat before sealing.

What maintenance or replacement will the 250 ml KH-series reactor need after repeated 240 °C cycles?

Inspect the PTFE liner for cracks or discoloration after each run and replace it once surface damage appears; the 0Cr18Ni9Ti body and bolts only need thread cleaning and light lubrication.

What is the first operating limit reached when the reactor runs at the maximum 240 °C for extended periods?

The 220 °C safety temperature is the first limit; exceeding it risks over-pressure beyond the 3 Mpa rating, so the heating rate must stay below 5 °C/min and cooling must be equally slow.
