Description
Technical field
The utility model relates to a kind of device for carrying out vacuum freeze drying to external diagnosis reagent calibration object.
Background technology
Vacuum freeze drying to need the solution of freeze-drying to be frozen into solid in advance, then under low-temp low-pressure condition, dewatered a kind of drying means is directly sublimed into from frozen state without liquid, current vacuum freezing drying device is that material is frozen into below eutectic temperature, make the ice that moisture becomes solid-state, then material is made to heat under cryogenic vacuum state, the moisture in material is made directly to be sublimed into steam by ice, current vacuum freezing drying device, reagent is placed on after on this vacuum freezing drying device, need with a cover body, reagent to be covered, so that reagent is hedged off from the outer world, in this vacuum freezing drying device, after reagent covers by cover body, cover body is fixing built on the sand, cover body is easily toppled over, make this vacuum freezing drying device safety in utilization poor.
Utility model content
Technical problem to be solved in the utility model is, provides and makes cover body be not easy the device for carrying out vacuum freeze drying to external diagnosis reagent calibration object of toppling over.
For solving the problems of the technologies described above, the device for carrying out vacuum freeze drying to external diagnosis reagent calibration object that the utility model provides, comprising:
One casing, this box house is provided with a cavity, is provided with a refrigeration part and a heating parts in this cavity, the upper surface of this casing is provided with the opening portion with cavity connects;
One cover body, this cover body is cylindrical shape and is transparence, and one end of this cover body is openend, and the other end of this cover body is closed; And
One vacuum pumping pump, the air entry of this vacuum pumping pump is by pipeline and cavity connects;
The upper surface of described casing offers an annular groove around opening portion, and the groove width of annular groove is greater than the wall thickness of cover body, cover body cover opening portion and the week of the openend of cover body along being placed in annular groove.
As preferably, between the outer wall of described cover body and the cell wall of annular groove, leave gap.
As preferably, described cover body is made up of glass.
After adopting above structure, the utility model compared with prior art, has following advantage:
In the utility model, when cover body is covered opening portion, the week of the openend of cover body is along being placed in annular groove, spacing fixation is played in the openend of annular groove to cover body, like this, make cover body fixing firm, be not easy to topple over, make this better for the device safety in utilization of external diagnosis reagent calibration object being carried out to vacuum freeze drying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the utility model comprises casing 1, cover body 2 and a vacuum pumping pump 3 for device external diagnosis reagent calibration object being carried out to vacuum freeze drying.
Described casing 1 inside is provided with a cavity 101, is provided with refrigeration part 102 and a heating parts 105, the upper surface of this casing 1 is provided with the opening portion 103 be communicated with cavity 101 in this cavity 101.
This cover body 2 is cylindrical shape and is transparence, and one end of this cover body 2 is openend, and the other end of this cover body 2 is closed, and the air entry of this vacuum pumping pump 3 is communicated with cavity 101 by pipeline.
The upper surface of described casing 1 offers an annular groove 104 around opening portion 103, this annular groove 104 is circular, the groove width of annular groove 104 is greater than the wall thickness of cover body 2, cover body 2 cover opening portion 103 and the week of the openend of cover body 2 along being placed in annular groove 104.
Gap is left between the outer wall of described cover body 2 and the cell wall of annular groove 104.
Described cover body 2 is made up of glass.
This cover body 2 can take off from casing 1, when reagent put into by needs, cover body 2 is taken off from casing 1, near the opening portion 103 reagent being put into casing 1, then cover body 2 is covered opening portion 103 and reagent, and make the week of the openend of cover body 2 along being placed in annular groove 104, then toward perfusion in annular groove 104 one circle high vacuum seal fat, high vacuum seal fat to week of the openend of cover body 2 along and the bottom of annular groove 104 between space play sealing function, make between the inside of cover body 2 and outside isolated, then refrigeration part 102 works, reagent is frozen into below eutectic point, make the ice that the moisture in reagent becomes solid-state, then vacuum pumping pump 3 works, make to form vacuum in cover body 2, then heating parts 105 works, moisture in reagent is made directly to be sublimed into steam by ice, complete the vacuum freeze drying to reagent.
Below only apply preferably example with regard to the utility model and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes done in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
