Hydrothermal & Solvothermal Research
The OPX-281 is designed for hydrothermal and solvothermal synthesis, where compatible chemical reactions are carried out in a sealed vessel under elevated temperature and pressure.
These techniques are widely used in materials science and research for producing or studying nanomaterials, crystalline compounds, catalysts, ceramics, and other advanced materials under controlled laboratory conditions.
SS 316 Construction
The outer reactor vessel is manufactured from SS 316 stainless steel, providing robust mechanical construction for laboratory applications. The stainless-steel outer jacket surrounds and supports the inner reaction chamber.
The actual chemical compatibility of the reactor depends on the liner material, reagents, temperature, pressure, concentration, and complete reactor configuration.
PTFE (Teflon) Lined Reactor
The PTFE-lined configuration is intended for compatible hydrothermal applications requiring chemical resistance. Based on the supplied specifications, the PTFE liner has a stated maximum temperature of approximately 220°C, with a recommended safe working limit of 200°C.
Operating limits should always follow the rating supplied with the specific liner and complete reactor assembly.
PPL Lined Reactor
For applications requiring higher temperature capability, a PPL-lined configuration may be used where compatible with the intended process.
According to the supplied specifications, PPL liners can support temperatures up to approximately 280°C, with a recommended working limit of around 260°C, subject to the rating of the actual reactor configuration.
Available Capacity Range
The Hydrothermal Autoclave series can be supplied in multiple capacities depending on laboratory requirements.
Threaded Type: Typically available from 10 mL to 500 mL.
Flange Type: Larger configurations may be available in 1 L, 1.5 L, and 2 L capacities.
The OPX-281 featured here has a 100 mL chamber capacity.
Working Purpose
The OPXICA OPX-281 Hydrothermal Autoclave provides a sealed reaction environment for compatible laboratory synthesis requiring elevated temperature and pressure. It is particularly useful in research involving material formation and chemical transformations that require hydrothermal or solvothermal conditions.
Researchers can use this type of reactor for applications involving nanoparticle synthesis, crystal growth, catalyst development, materials research, and chemical synthesis, provided the process remains within the rated limits of the reactor and liner.

- Quality-control and analytical research
Laboratory Safety & Operating Considerations
Because a hydrothermal autoclave operates under elevated temperature and pressure, it should only be operated by trained laboratory personnel according to the manufacturer’s operating manual and institutional safety procedures.
The reactor, liner, seals, threads, and closure components should be inspected before operation. Do not exceed the rated temperature, pressure, or filling limits of the specific assembly. The supplied guidance recommends keeping the filling level at 90% or less; some reactions may require a lower limit, so the validated procedure and manufacturer instructions should take priority.
The reactor should be allowed to cool and depressurize fully according to the manufacturer’s procedure before opening. Proper cleaning between compatible experiments is important to minimize contamination.
At the End
The OPXICA OPX-281 Hydrothermal Autoclave provides a specialized solution for scientific research involving elevated-temperature and elevated-pressure reactions. Its 100 mL chamber, SS 316 construction, and compatibility with specialized inner liners support a broad range of hydrothermal and solvothermal research applications.
For reliable operation, users should always follow the specified limits for the particular reactor body, liner, seals, temperature, pressure, and chemical system being used.
