It creates a sealed, high-temperature, high-pressure environment using strong acids or bases to rapidly digest otherwise insoluble substances, such as heavy metals, pesticide residues, food, sludge, rare earths, aquatic products, and organic matter. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"67\" data-end=\"340\"\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eFeaturing an innovative stepped-positioning PTFE liner, the design minimizes “cold flow” deformation after high-temperature cooling, preventing volume shrinkage and extending liner life. The reactor is precision-machined from non-magnetic ASIS 321 stainless steel, with a corrosion-resistant double-layer PTFE lining, and supports a maximum temperature of 260°C and pressure up to 3 MPa. With its sleek design, structural integrity, and ease of use, it is ideal for university labs, environmental monitoring, public health, and quality inspection applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"67\" data-end=\"340\"\u003e\u003cstrong\u003eA complete hydrothermal reactor set includes a stainless steel outer shell and a PTFE liner.
