Technical field
The utility model belongs to the technical field of centrifugation trim, more particularly to a kind of centrifugation balancing device.
Background technique
In laboratory centrifugation trim operation it is very frequent, at present trim mode mainly pass through laboratory technician pour into manually or
Partially liq is poured out, it is consistent for reaching both sides weight.However, manual trim often has that accuracy is not high, this will
Subsequent centrifugal effect and experimental result, and a large amount of times for expending experimental implementation are directly affected, in addition, trim inaccuracy also can
Centrifuge abrasion is caused to accelerate, noise vibration increases, and centrifuge service life is caused to substantially reduce.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of centrifugation balancing devices, realize automatic trim, use
It is convenient, improve the accuracy and efficiency of centrifugation trim.
Technical solution adopted by the utility model to solve its technical problems is provide a kind of centrifugation balancing device, including bottom
Seat, balance bracket, balancing pole, centrifuge tube fixing groove, pipettor, water tank and sensor, the balance bracket are set in pedestal
Portion, the balancing pole both ends are evenly connected to the top of balance bracket, and the both ends of the balancing pole are respectively equipped with same size
Opening upwards centrifuge tube fixing groove, inside described pipettor one end insertion water tank, the liquid outlet of the other end is correspondingly arranged in
The surface of one end centrifuge tube fixing groove, the pipettor are drawn water upwards by water pump, and the sensor is connected to pipettor
Water pump simultaneously controls water pump opening and closing by the induction information of detection balancing pole both ends horizontal balance.
The pipette of the pipettor is equipped with valve, and the valve is switched by the actuated signal control of sensor.
The horizontal both ends that the inner wall of the pedestal corresponds to balancing pole are respectively equipped with sensor, and two sensors receive induction
Water pump is controlled when signal to close.
The pedestal is the case structure of upper end opening.
The connection of the side of the water tank and pedestal.
Detachable, reducing hollow fixing sleeve is equipped with inside the centrifuge tube fixing groove.
Beneficial effect
In the present invention, water tank liquid is added into the centrifuge tube to trim by pipettor and carries out trim, to flat
When weighing apparatus bar both ends reach horizontal equilibrium, sensor detects balancing pole balanced signal, and then the water pump for controlling pipettor stops work
Make, trim is completed.Therefore, the utility model can be realized automatic liquid-feeding and the stopping of centrifugation trim, easy to use, be conducive to mention
The accuracy and efficiency of height centrifugation trim.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
A kind of centrifugation balancing device as shown in Figure 1, including pedestal 1, balance bracket 2, balancing pole 3, centrifuge tube fixing groove
5, pipettor 6, water tank 7 and sensor 9.
Pedestal 1 is the case structure of upper end opening, is made of stainless steel, and plays support and protects internal unit
Effect.Balance bracket 2 is set to inside pedestal 1, and 3 both ends of balancing pole are evenly connected to the top of balance bracket 2, forms balance
Formula structure.The both ends of balancing pole 3 are respectively equipped with the centrifuge tube fixing groove 5 of the opening upwards of same size, for placing centrifuge tube
Trim is carried out, dismountable hollow fixing sleeve is equipped with inside centrifuge tube fixing groove 5, hollow fixing sleeve is made of elastic material,
It can be suitable for the centrifuge tube of different size.
The horizontal both ends that the inner wall of pedestal 1 corresponds to balancing pole 3 are respectively equipped with sensor 9, and two sensors 9 can balance
3 both ends horizontal of bar generates inductive signal when balancing.
Water tank 7 is set to the side of pedestal 1 and connect with pedestal 1.Pipettor 6 includes pipette, water pump 8 and valve 4, is moved
The lower end of liquid pipe is inserted into the inside of water tank 7, and upper end liquid outlet is correspondingly arranged in the surface of one end centrifuge tube fixing groove 5, moves
Liquid device 6 is used to treat each other liquid feeding in the centrifuge tube of trim.Sensor 9 is connect with the water pump 8 of pipettor 6 and valve 4 respectively, passes through inspection
Survey the opening and closing of signal control water pump 8 and valve 4.
The centrifugation balancing device when in use, will need the empty centrifuge tube of trim to be placed into one end with pipettor 6
Centrifuge tube fixing groove 5 in；Carry sample liquid centrifuge tube to be centrifuged is placed in the centrifuge tube fixing groove 5 of the other end；Starting dress
It sets, water pump 8 and valve 4 are opened under the detection signal control of sensor 9, and liquid is added into the centrifuge tube to trim；When two
When holding centrifuge tube weight to reach one causes balancing pole 3 to tend to horizontal equilibrium state, the sensor 9 at both ends detects that equilibrium state is believed
Number, and then control water pump 8 and stop working immediately, while valve 4 is closed, liquid feeding is not continued to, namely complete trim work.
