Description
Technical field
This patent relates to a kind of chemical laboratory heating for dissolving instrument product, relates in particular to a kind of instrument of chemistry laboratory employing low-temperature heat sample dissolution.
Background technology
At present, in chemical laboratory, while adopting crucible, beaker or other vessel instrument dissolution in low temperature samples, generally adopt electric furnace, adjustable electric cooking stove or electric hot plate, and match with asbestos gauge.This mode generally there will not be any problem for crucibles such as the metal of serviceability temperature wider range, quartz, potteries, but for the lower non-metallic material instrument of serviceability temperature scope, as polytetrafluoroethylene (PTFE) crucible, just easily there is the too low molten sample of temperature not exclusively in above-mentioned mode of heating or excess Temperature damages crucible.Damage for fear of sample-dissoloing unit ware, a lot of laboratories adopt the molten sample of noble metal vessel, not only make cost increase, and have consumed a large amount of noble metal vessel, and environmental pollution also causes certain influence.Traditional mode of heating in addition, also has heating-up temperature fluctuation larger, and the phenomenon that sample jumps out or the dissolving cycle is long, easily appears in poor reproducibility.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, controls easy to usely, and cost is low, and instrument is dissolved in the effective laboratory low-temperature heat of temperature control.
Instrument is dissolved in the technical solution of the utility model a kind of laboratory low-temperature heat, it wraps low-temperature furnace 1, it is characterized in that: be provided with metal tray 2 in the top movable of described low-temperature furnace 1, in described metal tray 2, quartz sand layer 3 is housed, in described quartz sand layer 3, can be placed with heating vessel 4, be provided with power temperature controller 7 in the outside of described low-temperature furnace 1, described power temperature controller 7 is connected with a thermocouple temperature measurement instrument 5 by electric lead 6, the point for measuring temperature of described thermocouple temperature measurement instrument 5 is positioned at the top layer of described quartz sand layer 3, described power temperature controller 7 is also connected with described low-temperature furnace 1 by power line 8.
The beneficial effects of the utility model are to be provided with metal tray 2 by the top movable at described low-temperature furnace 1, in described metal tray 2, quartz sand layer 3 is housed, in described quartz sand layer 3, can be placed with heating vessel 4, be provided with power temperature controller 7 in the outside of described low-temperature furnace 1, described power temperature controller 7 is connected with a thermocouple temperature measurement instrument 5 by electric lead 6, the point for measuring temperature of described thermocouple temperature measurement instrument 5 is positioned at the top layer of described quartz sand layer 3, and described power temperature controller 7 is also connected with described low-temperature furnace 1 by power line 8; When work, by regulating the low-temperature furnace 1 of appropriate power as heating unit, be placed on corrosion resistant metal pallet 2 as support platform on low-temperature furnace 1, the quartz sand layer in certain particle size interval 3 is put into metal tray 2 as heat transmitting medium, heating vessel 4 is placed in quartz sand layer 3, heat not only evenly but also stable by sand bath, then by thermocouple temperature measurement instrument 5 thermometrics, and the point for measuring temperature of thermocouple temperature measurement instrument 5 is positioned to the top layer of quartz sand layer; Control power and the temperature of heating by electric cooker by power temperature controller 7, then molten sample temperature requirement per sample, Modulating Power temperature controller 7 also controls to suitable power and temperature, realize simple in structure, control easy to usely, cost is low, and the effective object of temperature control.
