What gum concentration must be to determine, change in concentration can influence testing result, can reduce the water volatilization in bottle in this way.So
And agarose needs to boil certain time and can be just completely dissolved, during which also need to stir or rock to accelerate dissolving and uniformly.
During stirring or rocking, especially in whipping process, moisture evaporation amount is big, influences final gel strength.Some experiment people
Member supplements the water of volatilization by the way of moisturizing after boiling dissolving, but is easy to produce error during moisturizing, it is difficult to
Reach accurate.On the other hand, because the DNA that severe toxicity is added with Ago-Gel is fitted together to reagent, if operating procedure is excessively cumbersome,
The easily probability of increase experiment accident.On the other hand, because the sepharose temperature after boiling is higher, easily scald tests people
Member, especially during bottle is rocked after boiling and accelerates agarose dissolving, hot gas can be outside preservative film or masking foil sealing part
Let out, easily scald experimenter.
Therefore, experimenter expects that can design one kind can be used for reagent to heat, and can effectively reduce water loss when boiling,
And the test glass with anti-scald function.
Utility model content
The purpose of this utility model is to provide a kind of test glass, water loss when can effectively reduce reagent heating, and has
There is anti-scald function, facilitate experimenter to operate.
To achieve the above object, a kind of test glass provided by the utility model, it includes cup and is sheathed on cup opening
Cup lid at mouthful, the cup lid include inner cap and the outer cover being sheathed on outside the inner cap, and the outer rim of the inner cap, which is provided with, to be used for
The outer flanging coordinated with cup opening, sink concavity for the middle part of the inner cap, it is described in cover provided with several stomatas.
Preferably, the cup opening is provided with heat insulation loop, and the outer cover passes through the heat insulation loop and cup activity
Connection.
Preferably, the heat insulation loop is provided with external screw thread, is to be threadedly coupled between the outer cover and the heat insulation loop.
Preferably, hasp is provided with the outer rim of the outer cover, is hasp connection between the outer cover and the heat insulation loop.
Preferably, the outer cover is provided with the stomata or air cleft for being used for gas circulation.
Preferably, the middle part of the inner cap, which is provided with, is used to accommodate the poke hole that stirring rod passes through.
Preferably, the inner cap uses elastic material.
Preferably, the inner cap uses silica gel material.
Preferably, the heat insulation loop uses silica gel material.
Preferably, the cup is conical flask.
A kind of test glass that above-mentioned technical proposal is provided, compared with prior art, its advantage includes：Pass through design
The inner cap of spill, vapor condenses and sunk by inner cap the concave panel formed and is back to when heating reagent after touching inner cap
In cup, the water loss of reagent is effectively reduced；The outer cover being sheathed on by design outside the inner cap, it is possible to achieve cup lid
Effect of heat insulation, prevent experimenter to be burned when holding test glass, there is anti-scald function, the operation of experimenter can be facilitated.
Brief description of the drawings
Fig. 1 is the structural representation of the test glass of embodiment of the present utility model,
Fig. 2 is the structure enlargement diagram of the A in Fig. 1.
Wherein, 1- cups, 3- inner caps, 4- outer covers, the outer flangings of 5-, 6- stomatas, 7- heat insulation loops, 8- hasps, 9- poke holes.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
Attached Fig. 1 and 2 is referred to, a kind of test glass provided by the utility model, it includes cup 1 and is sheathed on cup 1
The cup lid of opening, the cup lid include inner cap 3 and the outer cover 4 being sheathed on outside the inner cap 3, and the outer rim of the inner cap 3 is set
There are the outer flanging 5 for coordinating with the opening of cup 1, the sagging concavity in middle part of the inner cap 3, if the inner cap 3 is provided with
Dry stomata 6.
Based on the test glass of above-mentioned technical characteristic, by designing the inner cap 3 of spill, vapor touches when heating reagent
The concave panel formed is condensed and sunk by inner cap 3 after inner cap 3 to be back in cup 1, effectively reduces the water loss of reagent；It is logical
Cross the outer cover 4 that design is sheathed on outside the inner cap 3, it is possible to achieve the effect of heat insulation of cup lid, prevent the hand-held experiment of experimenter
