{"product_id":"ekmdjltbr","title":"ECS-KM Double-Jacket Low-Temperature Batch Reactor (-80~150℃, 0.6 MPa, 20 L), EKMDJLTBR","description":"\u003cp\u003eA low-temperature double-jacketed batch reactor (also known as a triple-walled reactor) is designed specifically for cryogenic chemical syntheses, organometallic reactions (such as Grignard formation or lithiation), bio-extractions, and low-temperature crystallizations down to -80℃ or lower. The key feature is the dual-concentric wall architecture: the inner jacket circulates the low-temperature heat-transfer fluid (HTF), while the sealed outer jacket is pulled under high vacuum to act as a thermal insulation barrier.\u003c\/p\u003e\n\u003cp data-path-to-node=\"0\"\u003eDouble jacket is essential for low-temperature processing due to the following reasons: (1) \u003cstrong\u003eElimination of Frost \u0026amp; Condensation\u003c\/strong\u003e: In a standard single-jacketed vessel operating at sub-zero temperatures (e.g., -40 to -80℃), ambient humidity rapidly freezes on the outer glass wall. Heavy frost buildup completely obscures the view inside and creates messy water runoff when thawing. The outer vacuum layer prevents external surface cooling below the ambient dew point. (2) \u003cstrong\u003eThermal Efficiency \u0026amp; Temperature Stability\u003c\/strong\u003e: Uninsulated single jacket walls lose significant cooling capacity to the surrounding room air. A vacuum-jacketed outer layer drastically reduces convective and conductive heat gain, keeping thermal stress low and allowing dynamic circulators (chillers) to reach and hold target cryogenic setpoints faster. (3) \u003cstrong\u003eOperator Safety\u003c\/strong\u003e: The outer wall stays near room temperature even when the inner chamber is at -80℃, preventing cold-contact burns (frostbite) during active sampling or material addition.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 595.1px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEKMDJLTBR (EKM-DJLTBR)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 67.2px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 67.2px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 67.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC220V±10%, single phase, 50\/60Hz, ~1000 W \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eA 1500 W converter can be used for AC110V condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 302.4px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 302.4px;\"\u003e\u003cem\u003eKey Features for Low-Temperature Batch Reactor\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 302.4px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eElectric-driven lifting the reactor cover up\/down (position sensor) and the reactor vessel is fixed. \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eVessel Material: SS316L\u003c\/li\u003e\n\u003cli\u003eVessel Volume: 20 L\u003c\/li\u003e\n\u003cli\u003eDesign Pressure: 0.6 MPa \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDesign Temperature: -80~150℃.
