The plate heats from 35 to 400°C and the stir drive runs 150–1,500 rpm, handling up to 5 L of liquid. Both values show on a digital display, and a warning LED lights whenever the plate is above 50°C. With the optional external probe, the controller holds the sample itself within ±1°C; clamp assembly H3770-CS mounts probes and thermometers.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e7 × 7 in chemical-resistant white ceramic top plate\u003c\/li\u003e\n\u003cli\u003eHeats 35–400°C; stirs 150–1,500 rpm\u003c\/li\u003e\n\u003cli\u003eStirs volumes up to 5 L\u003c\/li\u003e\n\u003cli\u003eHot-surface LED lights above 50°C\u003c\/li\u003e\n\u003cli\u003eOptional probe holds sample temperature within ±1°C\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\u003eH3770-HS \/ H3770-HS-E\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTemperature Range\u003c\/th\u003e\n\u003ctd\u003e35–400°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpeed Range\u003c\/th\u003e\n\u003ctd\u003e150–1,500 rpm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePlatform Dimensions\u003c\/th\u003e\n\u003ctd\u003e7 × 7 in (17.8 × 17.8 cm)\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\u003eMax Stirring Volume\u003c\/th\u003e\n\u003ctd\u003e5 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSample Temperature Control\u003c\/th\u003e\n\u003ctd\u003e±1°C with optional external probe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHot-Surface Indicator\u003c\/th\u003e\n\u003ctd\u003eLED, above 50°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e6.4 lb (2.9 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eElectrical\u003c\/th\u003e\n\u003ctd\u003e115 V or 230 V\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\u003eH3770-HS\u003c\/td\u003e\n\u003ctd\u003e115V, US plug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eH3770-HS-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\u003eDocuments\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.benchmarkscientific.com\/wp-content\/uploads\/2026\/08\/H3770-manual-Digital-Hotplate-stirrer.pdf\" target=\"_blank\" rel=\"noopener\"\u003eInstruction manual (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.benchmarkscientific.com\/wp-content\/uploads\/2020\/10\/H3770-Series-NEW-Hotplate-Brochure-HR-EM.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"Product\",\"@id\":\"https:\/\/labsupplies.com\/products\/benchmark-scientific-digital-hotplate-stirrer-h3770-hs#product\",\"brand\":{\"@type\":\"Brand\",\"name\":\"Benchmark Scientific\"},\"manufacturer\":{\"@type\":\"Organization\",\"name\":\"Benchmark Scientific\"}},{\"@type\":\"Offer\",\"@id\":\"https:\/\/labsupplies.com\/products\/benchmark-scientific-digital-hotplate-stirrer-h3770-hs?variant=67828495712488#offer\",\"mpn\":\"H3770-HS\",\"sku\":\"H3770-HS\"},{\"@type\":\"Offer\",\"@id\":\"https:\/\/labsupplies.com\/products\/benchmark-scientific-digital-hotplate-stirrer-h3770-hs?variant=67828495745256#offer\",\"mpn\":\"H3770-HS-E\",\"sku\":\"H3770-HS-E\"}]}\u003c\/script\u003e","brand":"Benchmark Scientific","offers":[{"title":"115V, US plug","offer_id":67828495712488,"sku":"H3770-HS","price":451.07,"currency_code":"USD","in_stock":true},{"title":"230V, European plug","offer_id":67828495745256,"sku":"H3770-HS-E","price":451.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0694\/5361\/1240\/files\/H3770-HS_20Closeup_20w_20flaskHR_20Editable_20.jpg?v=1790993298","url":"https:\/\/labsupplies.com\/products\/benchmark-scientific-digital-hotplate-stirrer-h3770-hs","provider":"LabSupplies.com","version":"1.0","type":"link"}
