{"product_id":"benchmark-scientific-digital-hotplate-h3770-h","title":"Benchmark Scientific Digital Hotplate H3770-H | 7 × 7 in Ceramic Top Plate, 35–400°C, Heat Only","description":"\u003cp\u003eH3770-H is the heat-only member of Benchmark's 7 × 7 in digital series, with no stirring drive. Its white ceramic top plate heats from 35 to 400°C under microprocessor control, and the set temperature is shown on a digital readout. A safety LED stays lit while the surface is hotter than 50°C. Connecting the optional external probe lets the hotplate regulate on the liquid temperature, holding it within ±1°C.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHeat only, 35–400°C on a 7 × 7 in ceramic plate\u003c\/li\u003e\n\u003cli\u003eChemical-resistant white ceramic surface\u003c\/li\u003e\n\u003cli\u003eDigital temperature setting and readout\u003c\/li\u003e\n\u003cli\u003eSafety LED warns of a plate above 50°C\u003c\/li\u003e\n\u003cli\u003eOptional probe regulates sample to ±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-H \/ H3770-H-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\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\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-H\u003c\/td\u003e\n\u003ctd\u003e115V, US plug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eH3770-H-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-h3770-h#product\",\"brand\":{\"@type\":\"Brand\",\"name\":\"Benchmark Scientific\"},\"manufacturer\":{\"@type\":\"Organization\",\"name\":\"Benchmark Scientific\"}},{\"@type\":\"Offer\",\"@id\":\"https:\/\/labsupplies.com\/products\/benchmark-scientific-digital-hotplate-h3770-h?variant=67828495778024#offer\",\"mpn\":\"H3770-H\",\"sku\":\"H3770-H\"},{\"@type\":\"Offer\",\"@id\":\"https:\/\/labsupplies.com\/products\/benchmark-scientific-digital-hotplate-h3770-h?variant=67828495810792#offer\",\"mpn\":\"H3770-H-E\",\"sku\":\"H3770-H-E\"}]}\u003c\/script\u003e","brand":"Benchmark Scientific","offers":[{"title":"115V, US plug","offer_id":67828495778024,"sku":"H3770-H","price":309.65,"currency_code":"USD","in_stock":true},{"title":"230V, European plug","offer_id":67828495810792,"sku":"H3770-H-E","price":309.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0694\/5361\/1240\/files\/H3770-H_20Digital_20Hotplate.jpg?v=1790993307","url":"https:\/\/labsupplies.com\/products\/benchmark-scientific-digital-hotplate-h3770-h","provider":"LabSupplies.com","version":"1.0","type":"link"}
