Description
Technical field
The utility model relates to melting point substance measuring devices, are specifically exactly to be related to a kind of dual-purpose micro-meldometer of improvement
Heating furnace warm table.
Background technique
In Physical Experiment, it is often required to the fusing point with micro-meldometer measurement of species.When measurement, sample is placed in aobvious
The metal thermal station of micro- melting point apparatus is gradually heated up, and under microscopical observation, when sample becomes liquid from solid-state, records thermal station
Temperature, the as fusing point of the substance.A kind of existing dual-purpose thermal station of micro-meldometer, can add sample with two methods
Heat: the first is that sample is mounted in capillary, is inserted into thermal station heating；Second is that sample is placed on to sheet glass (referred to as to carry
Slide) on, it to prevent the sample of powdered from dispersing, covers sheet glass (referred to as coverslip) again on sample, is placed in thermal station and adds
Heat.But this dual-purpose thermal station has the following problems: if 1. heating same sample using both the above method, the fusing point measured
Differ larger because on glass slide sample heat when, a part of heat consumption of thermal station in the heating to surrounding air,
Affect the consistency of measurement result；And after being measured, when removing glass slide from the thermal station of high temperature, it is easy operation of burning
The both hands of person；2. use capillary heating, since the capilar bore of thermal station side is smaller, find accurately it is harder, if firmly slightly
Accidentally, it is easy to fracture in capillary, unnecessary waste is caused to expensive sample；
Chinese patent ZL200920286276.5 is for a kind of dual-purpose micro melting point apparatus heating stove, including thermal station, insulation cover, hair
Tubule guide pad hangs down its main feature is that there are disk side protruding upward, positioning convex platform in the two sides and one end on thermal station with thermometer hole
The perpendicular airflow hole for wearing thermal station directly communicated；Insulation cover can be disposed on thermal station guard ring, to form a closed sample
Heating space；Capillary guide pad is installed on Instrument shell, capillary guide groove above and capillary hole location in thermal station
Set correspondence.In application glass slide method measurement, safety easy to operate, and improve the measuring accuracy of fusing point；It is applying
It is easy to operate accurate when capillary tube method measures, and improve measuring speed and sample utilisation
But when measuring the substance of non-non-powder, due to using carrying of the glass slide as test substance in above-mentioned patent
Body first heats glass slide, is then passed when the metal thermal station that sample is placed in micro-meldometer is gradually heated up
It leads to the sample to be tested on glass slide is prevented, since glass slide general thickness is all thicker, area is also larger, required preheating
Time will be longer, while also resulting in the waste of energy.
Utility model content
The purpose of this utility model is aiming at above-mentioned existing dual-purpose micro melting point apparatus heating stove with warm table using load
Slide is long as the supporting body preheating time of determinand, the technological deficiency of waste of energy, provides a kind of the dual-purpose micro- molten of improvement
Point instrument heating furnace warm table, the supporting body of object under test is changed into coverslip, can be improved the efficiency of warm table heat transfer,
Shorten dual-purpose micro melting point apparatus heating stove warm table preheating time.
Technical solution
In order to achieve the above technical purposes, a kind of dual-purpose micro melting point apparatus heating stove of improvement provided by the utility model is used
Warm table, it includes thermal station ontology, and the thermal station ontology is equipped with installation slotted eye, and the installation slotted eye is provided with electric heating tube,
It is characterized by: the upper surface of corresponding thermal station ontology is equipped with coverslip mounting groove above the electric heating tube, coverslip is set
In the coverslip mounting groove, the trench bottom of the coverslip mounting groove is equipped with capillary guide groove, and capillary is along described
Capillary guide groove protrudes into the coverslip mounting groove, and the capillary guide groove is located at one in the coverslip mounting groove
End is equipped with light hole in the corresponding position of the thermal station ontology.
Further, at least 2 coverslips are located in the coverslip mounting groove, test substance is by 2 coverslips
Clamping.
Further, the light hole is corresponding with the position of the test substance through the thermal station ontology.
Preferably, described installation slotted eye at least two, point column light hole two sides.
Beneficial effect
The dual-purpose micro melting point apparatus heating stove warm table of a kind of improvement provided by the utility model, by holding for object under test
Carrier, which is changed, can be improved warm table heat transfer since the area and thickness of coverslip are all smaller than glass slide at coverslip
Efficiency shortens dual-purpose micro melting point apparatus heating stove warm table preheating time, while increasing capillary guide groove and can be avoided hair
Tubule fractures when being inserted into thermal station ontology.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model embodiment.
Attached drawing 2 is the structural schematic diagram of the utility model embodiment overlook direction.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described further.
Embodiment
As shown in figure 1 and 2, the dual-purpose micro melting point apparatus heating stove warm table of a kind of improvement, it includes thermal station ontology
1, the thermal station ontology 1 is equipped with installation slotted eye 101, and in the present embodiment, described 101 at least two of installation slotted eye, point column are described logical
