Abstract
The invention discloses a heater used for magnetic bead capture instrument, which comprises a disc which is uniformly provided with slots on the circumference. Hot blocks are arranged in certain slots; and close heat conducting blocks, heating device and radiating fins are tightly fit on the disc and below the hot blocks in sequence. During heating, reagent plates filled with a biochemical reaction reagent are placed on the hot blocks and the heating device are powered on; then the heat generated by the heating devices is transferred on the reagent plates by the heat conducting blocks and the hot blocks in sequence; the radiating fins are fixed below the heating devices; and the heating devices can more quickly transfer heat with the air through the radiating fins; the disc can rotate to drive a heating part and a heat transfer part fixed on the disc to rotate together; in this way, the reagent plates can be under a constant heating state no matter on which position the disc is stayed; therefore, operations can be implemented on other reagent plates on the disc simultaneously when heating, thus realizing automatic working process with high efficiency and high flux, and improving the working efficiency to a great extent. The heater used for magnetic bead capture instrument has the advantages of simple structure, small size and low cost.
Description
Technical field
The present invention relates to heater field, particularly relate to a kind of heater for magnetic capture instrument.
Background technology
The existing heater for biochemical reaction is broadly divided into following two kinds:
1, heater is fixed;
2, heater is a direction or multiple directions traveling priority.
The heater of these two kinds of biochemical reactions has certain defect: the first heater underaction, if will realize automation and high flux, and having relatively high expectations to other parts.Although the second heater can move in to a certain degree, there is certain flexibility, but the design cost of this device and production cost are higher, control complicated, and the space taking is larger, and movably scope can only be confined to the rectilinear motion of one or several direction.
Summary of the invention
Technical problem to be solved by this invention be in prior art, install underaction, complex structure, cost higher, take up room larger, be difficult to realize automation and high-throughout shortcoming, and a kind of heater for biochemical reaction rotating proposing.Device of the present invention can rotate arbitrarily in 360 ° of circumference range, can realize automation, high flux, reaches high efficiency requirement.
The present invention requires the technical problem solving to be achieved through the following technical solutions:
A heater for magnetic capture instrument, comprises heater element, hot piece, heat-conducting block, disk; On the circumference of described disk, be evenly equipped with groove, wherein have at least a groove to have heating function, in groove, place agent plate, between the described trench bottom that has a heating function and agent plate, place hot piece, lower disk surface, the position corresponding with groove be heat-conducting block fixedly, described heat-conducting block below fixed heater part, described disk can together rotate around disc centre with the hot piece, heat-conducting block, the heater element that are fixed thereon, so that disk can be in arbitrary position heating of 360 ° of circumference.
Under described heater element, settle fin, heater element upper surface and heat-conducting block laminating, lower surface and fin laminating, described heat-conducting block, heater element, fin are fixed together by press strip.
Described heat-conducting block and the laminating of hot piece.
The upper surface of described hot piece matches with the shape of agent plate lower surface, to guarantee that hot piece contacts with agent plate maximum area.
Owing to having adopted technique scheme, the present invention compared with prior art, has following features: the present invention can realize automation and the high flux of biochemical reaction, thereby greatly increase work efficiency, and device volume of the present invention is little, takes up room little, simple in structure, low cost of manufacture.

Fig. 3 is upward view of the present invention.
Fig. 4 is top view of the present invention.
In figure, 1-heater element, 2-fin, 3-agent plate, the hot piece of 4-, 5-disk, 6-heat-conducting block, 7-press strip.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the upper surface of heater element 1 and heat-conducting block 6 laminatings, heat-conducting block 6 and hot piece 4 laminatings, heat heater element 1 being produced by heat-conducting block 6 passes to hot piece 4.On the excircle of disk 5, be evenly equipped with some grooves, hot piece 4 is placed in groove wherein, and agent plate 3 is directly placed in the groove that has heating function on disk 5, by the hot piece 4 that is positioned at its below, it is heated.The lower surface of heater element 1 and fin 2 laminatings, can carry out energy transmission with air faster by fin 2.Heat-conducting block 6 is fixed on disk 5 lower surfaces, by press strip 7, heater element 1, fin 2 and heat-conducting block 6 is fixed together.Like this, each parts of whole heater are just in a relatively-stationary position.When disk 5 is around its center rotating, just can drive the heater element 1, heat-conducting block 6, hot piece 4 and the fin 2 that are fixed thereon together to rotate.No matter disk 5 rotates to any position, and biochemical reaction reagent can both be constant in heated condition.
Heater specific operation process of the present invention is as follows:
First agent plate 3 is placed into disk 5(and has heating function) groove in, at the interior filling reaction liquid of agent plate 3, then make heater element 1 heat subsequently.In heating, disk 5 rotates, and allows the position of next groove on disk 5 groove in heating, and another agent plate is placed in this dead slot, this agent plate is carried out to the work such as imbibition, liquid feeding.Like this, by disk 5, rotate, the hot piece 4 that drive is fixed thereon, heat-conducting block 6, heater element 1, fin 2 together rotate, when not affecting original heating work, can also operate other agent plate, increase work efficiency to a great extent, thus the high efficiency of realization, high-throughout automatically working process.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
