Abstract
Disclosed is a gravity flow type polyacrylamide gel injection device. The gravity flow type polyacrylamide gel injection device includes a liquid storage barrel, a top part of which is open. A bottom part of the liquid storage barrel is provided with a liquid discharging opening, which is connected with an end of a liquid guiding pipe. The other end of the liquid guiding pipe is provided with a flat mouth, the thickness of which is less than or equal to 0.5 mm. A switch is disposed at the connection part of the liquid discharging opening and the liquid guiding pipe. Flow rate of the gel is controlled through a combining mode of changing a pressure at the liquid bottom by adjusting the height of the liquid and controlling a flow valve, according to the theory that the pressure of the liquid is in proportion to the height of the liquid. Bubbles numbers in the injected gel is decreased, by discharging bubbles existed in the flow guiding pipe that containing gel out before the gel is injected according to a principle of bubble floating. A flat mouth is disposed at the outlet part of the flow guiding pipe, which facilitates injection between the two glass boards and improves uniformity of the injected gel.
Description
Technical field
The utility model relates to a kind of gravity flow polyacrylamide gel device for casting.
Background technology
In molecular biology research, often can use the making of polyacrylate hydrogel.The general encapsulating bottle encapsulating that uses the syringe encapsulating or pass through squash type in gel manufacturing process.During the syringe encapsulating, in the process that advances because the friction of syringe piston and wall is irregular, propelling easily occurs irregular, produce bubble and formation gel density irregularity when causing the perfusion gel in the middle of glass plate, make the phenomenon that can occur the banding pattern bending at the electrophoresis of running out of.Adopt the encapsulating bottle by the extruding encapsulating, return-air can occur after once extruding is completed, also easily cause the gel of perfusion to produce bubble.
Summary of the invention
The purpose of this utility model provides a kind of gravity flow polyacrylamide gel device for casting, can overcome the defective that existing method of operating easily produces bubble, pours into uniformly.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of gravity flow polyacrylamide gel device for casting, comprise the liquid storing barrel that the top is opened wide, the bottom of liquid storing barrel is provided with tap hole, tap hole connects mozzle, the other end of mozzle is provided with the flat mouth, the thickness≤0.5mm of flat mouth, and described tap hole and mozzle junction are provided with switch.
The top of described liquid storing barrel is provided with the edge of outside projection, makes when grasping, and is difficult for landing from hand.
Described switch is provided with the external control bar, and the end of external control bar is provided with bend, has angle between external control bar and liquid storing barrel outer wall, and also is provided with spring between external control bar and liquid storing barrel outer wall.Switch is in closed condition when spring is in deployed condition, when pressing the external control bar to the direction of liquid storing barrel, and spring-compressed, switch is opened gradually.The amplitude that spring is pressed is larger, and the permeability of switch is larger, and the liquid of liquid storing barrel more easily circulates.The design of bend facilitates the staff to adopt finger to control in addition.
Also be provided with scale on the outer wall of described liquid storing barrel, can grasp more intuitively the volume of liquid in liquid storing barrel.
Described mozzle and flat mouth junction are provided with hand holding handle, the convenient flat mouth of controlling.
The capacity of described liquid storing barrel is 〉=100ml that mozzle adopts the smooth transparent plastic hose of internal diameter 3-5mm to make.
The utility model is the principle of p=ρ gh according to fluid pressure to highly being directly proportional, and controls the flow velocity of coagulant liquid by the dual mode of regulating Level Change liquid bottom pressure size and control flow valve.Based on the principle of bubble floating, will exist before gel the bubble in the mozzle of gel fully to discharge in perfusion, the bubble that reduces in the perfusion gel exists.The exit of mozzle is provided with flat flat mouth, more is conducive to the homogeneity of the gel of perfusion between two glass plates and perfusion.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises the liquid storing barrel 1 that the top is opened wide, the bottom be provided with tap hole 2, tap hole 2 connects mozzle 3, the other end of mozzle is provided with flat mouth 4, the thickness≤0.5mm of flat mouth, and described tap hole 2 is provided with switch 5 with mozzle 3 junctions.
The top of described liquid storing barrel 1 is provided with the edge 11 of outside projection.
Described switch 5 is provided with external control bar 51, and the end of external control bar 51 is provided with bend 52, has angle between external control bar 51 and liquid storing barrel 1 outer wall, and also is provided with spring 53 between external control bar 51 and liquid storing barrel 1 outer wall.
Also be provided with scale 12 on the outer wall of described liquid storing barrel 1.
Described mozzle 3 is provided with hand holding handle 6 with flat mouth 4 junctions.
Capacity 〉=the 100ml of described liquid storing barrel 1, mozzle 3 adopts the smooth transparent plastic hose of internal diameter 3-5mm to make.
When using the utility model, first the polyacrylamide gel solution that configures is poured in liquid storing barrel 1, by gauge tap 5 and raise the height of the flat mouth 4 on mozzle 3, make the air in mozzle discharge by coagulant liquid, until flat mouth 4 places of mozzle are when being full of coagulant liquid, then closing switch inserts flat mouth 4 between mounted glass plate gap, with the middle finger of holding liquid storing barrel container hand or forefinger tension bend 52, encapsulating begins.In the encapsulating process, can control by the height of regulating liquid storing barrel 1 pressure of flat mouth 4, perhaps control the size of flow and interrupt by switch 5.
