Stainless steel autoclave with PTFE liner, 25 ml capacity

HNZXIB

HNZXIB 25ml Hydrothermal Synthesis Reactor 240°C PTFE KH series

SKU CH-9P67-1Z3G5

A 25 ml pressure reactor with a PTFE lining and non-magnetic stainless steel body, rated to 240 °C for hydrothermal synthesis and sample digestion

  • Total capacity25ml
  • Temperature rangeRT~240 °C
  • Product typePressure Reactor
  • Main materialSteel
  • 25 ml capacity enables small-scale hydrothermal synthesis
  • PTFE inner lining resists acids and alkalis for sample integrity
  • Non-magnetic 0Cr18Ni9Ti stainless steel shell adds structural safety
  • Operates up to 240 °C with 220 °C security limit
  • Heating and cooling rates below 5 °C/min protect vessel integrity

Capacity and Purpose

The HNZXIB KH-25 is a 25 ml hydrothermal synthesis reactor built for laboratory digestion and small-scale synthesis. It serves researchers, teaching labs and quality-control units that need a sealed vessel for acid or alkali treatment of samples such as heavy metals, pesticides or organic matter.

Build and Daily Use

The reactor body uses non-magnetic 0Cr18Ni9Ti stainless steel with a PTFE inner liner that resists both acids and alkalis. A wooden case protects the unit during transit, while the screw-top closure and double-layer protection simplify loading, sealing and cleaning between runs.

Temperature and Pressure Limits

Operation is rated from room temperature up to 240 °C with a safety ceiling of 220 °C, and heating or cooling rates must stay below 5 °C per minute. The vessel withstands 3 MPa safety pressure, and filling must not exceed 80 % of the 25 ml capacity to avoid over-pressurisation.

Questions about this item

What is the maximum operating temperature and safety temperature limit for this reactor?

The reactor operates up to 240 °C with a safety temperature limit of 220 °C to prevent overheating during experiments.

What are the physical capacity and fill limits for the PTFE liner?

The vessel holds 25 ml total volume and should not be filled beyond 80 % to allow safe pressure expansion.

How should the reactor be heated and cooled to avoid damage?

Heat and cool at rates below 5 °C per minute and only open the lid after the vessel has returned to room temperature naturally.
