Wide Opening, Easy Handling: The 7.1" x 6.3" x 5.91" wide tank and 6 L capacity make pouring, loading, and cleaning smooth and effortless. Our laboratory high-temperature circulating oil bath easily fits large containers and improves workflow efficiency Flexible Use: Our lab constant temperature heating tank supports internal and external circulation. Maintain a stable bath temp for precise work, or pump constant-temp liquid to external devices with a 3 m lift height to create a secondary thermal field Accurate Temperature Control: Our high-temperature circulating oil bath achieves up to 300℃ with 0.01℃ precision. The PID system automatically tunes temperature response for quick, stable heating and consistent results Built to Last: This laboratory heating circulator is made of thick 304 stainless steel top and inner chamber, easy to clean. The compression-to-thread adapter design supports multiple pipe types and is compatible with corrugated tubes for high-temp setups Versatile Use: The pure copper motor runs quietly and maintains stable circulation for uniform heating. This high temperature circulator is suited for biological and physical science work, including biotechnology, food processing, metallurgy, and more
