A microprocessor with turn-knob control sets and holds stir speed between 60 and 1,500 rpm, and a front-panel LED shows when stirring is active. The square top takes common borosilicate beakers, flasks and bottles, and the compact body fits on crowded benches or inside a bio-hood. It weighs 9 lb and is offered in 115V and 230V versions.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStir speed 60–1,500 rpm, set with a microprocessor-controlled turn knob\u003c\/li\u003e\n\u003cli\u003eSquare, chemical-resistant white ceramic top\u003c\/li\u003e\n\u003cli\u003eFront-panel LED indicates when the stir function is on\u003c\/li\u003e\n\u003cli\u003eCompact body for crowded benchtops and bio-hoods\u003c\/li\u003e\n\u003cli\u003eWeighs 9 lb (4 kg); 115V and 230V versions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eBenchmark Scientific\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCatalog number\u003c\/th\u003e\n\u003ctd\u003eH4000-S \/ H4000-S-E\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFunction\u003c\/th\u003e\n\u003ctd\u003eStir only (no heating)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpeed Range\u003c\/th\u003e\n\u003ctd\u003e60–1,500 rpm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTop Plate\u003c\/th\u003e\n\u003ctd\u003eWhite ceramic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e9 lb (4 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eElectrical\u003c\/th\u003e\n\u003ctd\u003e115 V, US plug (H4000-S); 230 V, European plug (H4000-S-E)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e2 Years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eOrdering information\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eCatalog number\u003c\/th\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eH4000-S\u003c\/td\u003e\n\u003ctd\u003e115V, US plug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eH4000-S-E\u003c\/td\u003e\n\u003ctd\u003e230V, European plug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eQuestions about the Magnetic Stirrer H4000-S\u003c\/h2\u003e\u003ch3\u003eWhat speed and stirring volume does the Magnetic Stirrer H4000-S handle?\u003c\/h3\u003e\u003cp\u003eThe Magnetic Stirrer H4000-S stirs at 60–1,500 rpm, on a white ceramic top plate.\u003c\/p\u003e\u003ch3\u003eIs the Magnetic Stirrer H4000-S available with a European plug?\u003c\/h3\u003e\u003cp\u003eYes.
