It is easy to clean in the event of accidental spills of solvents, oils, or other contaminants.\u003c\/p\u003e\n\u003cp\u003eThe corrosion-resistant all-metal housing provides efficient heat dissipation and reliable fire protection.\u003c\/p\u003e\n\u003cp\u003eAn optimized fluid-guiding platform and raised spill-protection edge help prevent liquids from entering the unit and damaging internal electronic components.\u003c\/p\u003e\n\u003cp\u003eThe safety lock prevents accidental changes to the operating status.\u003c\/p\u003e\n\u003cp\u003eA built-in buzzer provides an audible alert when a fault occurs or when the timer countdown is complete.\u003c\/p\u003e\n\u003cp\u003eThe residual heat warning function enhances operational safety. When the plate temperature exceeds 50°C, the display flashes “HOT” after heating is turned off. Even after the power is switched off, the “HOT” warning continues to flash, reminding users that the surface remains hot.\u003c\/p\u003e\n\u003cp\u003eTwo independent safety circuits continuously monitor the device. In the event of overheating or sensor failure, the unit displays an error and stops heating. In the event of a short circuit, the device automatically cuts off power to protect the operator.\u003c\/p\u003e\n\u003cp\u003eThe LCD screen clearly displays both set and real-time values for time and temperature, ensuring intuitive operation.\u003c\/p\u003e\n\u003cp\u003eThe built-in timer supports a setting range from 1 minute to 99 hours and 59 minutes. Heating stops automatically when the countdown ends, helping prevent thermal damage to samples.\u003c\/p\u003e\n\u003cp\u003eRemote control functionality allows the unit to be connected to a computer for convenient operation.\u003c\/p\u003e\n\u003cp\u003eThe safety temperature limit can be set according to application requirements.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eProduct Applications：\u003c\/p\u003e\n\u003cp\u003eHigh-boiling acid digestion of minerals; preparation of nanomaterials and inorganic materials; sample ashing and sintering of metal catalysts; rapid removal of high-boiling solvents and sample drying; rapid sample concentration and drying; pre-treatment for analytical testing; pre-treatment of environmental water samples, soil, and pollutant samples.\u003c\/p\u003e\n\u003cp\u003eTarget Customers：\u003c\/p\u003e\n\u003cp\u003eR\u0026amp;D laboratories in mineral processing and metallurgical production industries; environmental monitoring stations for heavy metal pollutants in soil and water; university research laboratories in petrochemical and functional materials; R\u0026amp;D laboratories for battery electrode materials.\u003c\/p\u003e","brand":"DLAB US","offers":[{"title":"Default Title","offer_id":48300330123478,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/3583\/5350\/files\/DHP7-550-1.webp?v=1779958945","url":"https:\/\/dlab-us.myshopify.com\/products\/dhp7-550-lcd-digital-7-inch-timed-heating-hotplate","provider":"DLAB US","version":"1.0","type":"link"}
