Summary of the invention
The application provides a kind of novel reaction cup.
According to the application's first aspect, the application provides a kind of reaction cup, described reaction cup comprises holding part, described holding part has elongated reaction chamber, be used for depositing reaction solution, described reaction cup also comprises fluid injection portion, and described fluid injection portion has the fluid injection wall flowing down for guiding liquid being obliquely installed, the lower end of described fluid injection wall is connected with holding part, and fluid injection liquid can flow in reaction chamber along fluid injection wall.
As the further improvement of described reaction cup, described fluid injection portion is up big and down small cylindrical shell, and the inwall of described cylindrical shell is described fluid injection wall, and the lower end of described cylindrical shell is connected in the upper end of holding part.
Further improvement as described reaction cup, described holding part comprises pillar buoy and conically shaped, described pillar buoy has cylinder chamber, described conically shaped has conical cavity, described conically shaped is connected in pillar buoy lower end, described cylinder chamber and conical cavity are communicated with the described reaction chamber of formation, the bottom seal of described conical cavity.
As the further improvement of described reaction cup, the bottom of described conical cavity is spheric.
As the further improvement of described reaction cup, described reaction cup also comprises the clamping part for manipulator clamping, and described clamping part, holding part and fluid injection portion one are fixed.
As the further improvement of described reaction cup, described clamping part is tubular, and it is arranged at the upper end of fluid injection portion.
As the further improvement of described reaction cup, the depth size of described reaction chamber is the more than 5 times of cylinder chamber diameter.
The application's beneficial effect is:
The reaction cup that the application provides, it is except having holding part, also there is fluid injection portion, this fluid injection portion has the fluid injection wall being obliquely installed, the lower end of fluid injection wall is connected with the upper end of holding part, utilizes fluid injection instrument (as discharge opeing pin) by liquid fluid injection wall during fluid injection, and fluid injection liquid can flow in reaction chamber along fluid injection wall, avoid directly splashing into liquid and cause liquid splash, reduce crossed contamination.
Further, also can make fluid injection portion is up big and down small cylindrical shell, and its lower end osculum connects with the upper end of holding part, and liquid runs down barrel slowly flow in reaction chamber through osculum downwards.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the application's reaction cup;
Fig. 2 is fluid injection schematic diagram embodiment illustrated in fig. 1;
Fig. 3 is the mobile schematic diagram of clamping embodiment illustrated in fig. 1.
Embodiment
Below by embodiment, by reference to the accompanying drawings the present invention is described in further detail.The application can realize with multiple different form, is not limited to the described embodiment of the present embodiment.The object that following embodiment is provided is to be convenient to this to the clearer thorough understanding of application disclosure.
Embodiment mono-:
Please refer to Fig. 1, reaction cup 1 comprises clamping part 2, fluid injection portion 3 and holding part.
As illustrated in fig. 1 and 2, this holding part has elongated reaction chamber 6, for accommodating reaction solution.
In the present embodiment one, holding part comprises pillar buoy 4 and conically shaped 5.Pillar buoy 4 has cylinder chamber, and conically shaped 5 has conical cavity, and conically shaped 5 is connected in pillar buoy 4 lower ends, and cylinder chamber and conical cavity are communicated with formation reaction chamber 6.The bottom seal of conical cavity, and this bottom can be spheric.Through experimental verification, the shape of this reaction chamber is convenient to mixing of under the lower speed that mixes realization response liquid, reduces and spatters liquid risk.
According to this area general knowledge, when the degree of depth of reaction chamber 6 is greater than the diameter of tube chamber, think that this reaction chamber is elongated reaction chamber 6.
In the present embodiment one, the degree of depth of reaction chamber 6 can be for the diameter of cylinder chamber be more than 5 times, and these 5 times comprise 5 times above, and the reaction chamber 6 of this ratio can reduce and while mixing reaction solution, spills drop, thereby reduces the probability of crossed contamination.
And in other embodiments, reaction chamber 6 can be also separately cylindricality or taper, or be other reaction cup 1 shapes.
This fluid injection portion 3 is up big and down small cylindrical shell, the inwall of cylindrical shell is fluid injection wall, fluid injection wall is obliquely installed, the lower end of cylindrical shell is connected in the upper end of holding part, as shown in Figure 2, utilizes fluid injection instrument (as discharge opeing pin 7) by liquid fluid injection wall during fluid injection, fluid injection liquid can flow into along fluid injection wall the chamber wall of reaction chamber 6, and then flow in reaction chamber 6, avoid directly splashing into liquid and cause liquid splash, reduce crossed contamination.
Certainly, in other embodiments, fluid injection portion also can not be arranged to tubular, for example, a tilt component is set separately as fluid injection portion, and this tilt component stretches out from the upper end of holding part, and it has scarp as fluid injection wall.Further, groove type also can be made in this scarp, and groove, by guiding fluid reaction chamber 6, avoids liquid to leak from scarp side.
This clamping part 2 is when needs mobile response cup 1, is convenient to the operations such as manipulator clamping reaction cup 1 moves.As shown in Figure 3, mechanical manipulator 8 drive-motor driving device hand finger parts 9 clamp clamping part 2, thereby reaction cup 1 is moved with mechanical manipulator 8.Certainly, in other embodiments, if reaction cup 1 is from start to finish without relatively moving, also can save this clamping part 2.
For the ease of mould molding, the reaction cup 1 that the present embodiment provides is the revolution symmetrical container of upper end open, if clamping part 2, pillar buoy 4 are all cylindrical.And in other embodiments, clamping part 2, fluid injection portion 3 and holding part can be also square cylinders.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace.
