Description
Technical field
The utility model relates to a kind of utensil of use for laboratory, specifically a kind of simple glass pipette Rapid Cleaning in medicine, chemical industry, scientific research or other field laboratory, inspection laboratory and get liquid servicing unit.
Background technology
The accurate quantitative analysis often adopting pipette to carry out a small amount of fluid sample in the laboratory of field of medicine and chemical technology or control laboratory at present pipettes.When carrying out getting liquid, use rubber pipette bulb from pipette upper port by after the height that needs in liquid suction duct, remove rubber pipette bulb rapidly and block pipette upper port with finger, by controlling discharge air in hand point tube thus realize pipetting of liquid.The cleaning of pipette and rinse process are as got liquid process.
In the inspection and analytic process of reality, for ensureing the accuracy pipetting sample, must through repeatedly cleaning and pipetting of sample can being implemented after rinse before pipette uses, the discharging of waste liquid inconvenience of cleaning and rinse in operating process, length consuming time, workload is large, when particularly using same pipette to carry out pipetting of multiple sample, waste time and energy especially, complicated loaded down with trivial details.
Summary of the invention
The purpose of this utility model be for common pipette above-mentioned cleaning and get the deficiency of liquid, and a kind of the upper end that pipette need be installed on device is provided, just can realize automatic cleaning, rinse, absorption and effluent discharge function pipette Rapid Cleaning and get liquid servicing unit.
To achieve these goals, technical solution adopted in the utility model is: provide a kind of pipette Rapid Cleaning and get liquid servicing unit, comprise three-way pipe, waste liquid collection vessel and negative pressure generator, two ports opposing upper and lower are had in described three-way pipe, three-way pipe lower port is connected with flexible rubber interface, and described interface is connected with pipette; Be provided with valve in 3rd port of three-way pipe, the 3rd port of three-way pipe connects waste liquid collection vessel by flexible pipe A, and waste liquid collection vessel connects negative pressure generator by flexible pipe B.
Described negative pressure generator is the general water-jet type vavuum pump in a kind of small-sized vavuum pump or laboratory.
Two kinds of described vavuum pumps control the work of vavuum pump by floor push.
Pipette Rapid Cleaning of the present utility model and get the beneficial effect that liquid servicing unit compared with prior art has and be: this servicing unit coordinates existing pipette to use, highly versatile, simple to operation, automaticity is high, time saving and energy saving, can greatly increase work efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of pipette Rapid Cleaning of the present utility model and the structural representation getting liquid servicing unit.
In figure: 1-three-way pipe, 2-waste liquid collection vessel, 3-negative pressure generator, 4-pipette, 5-upper port, 6-lower port, 7-three-way pipe the 3rd port, 8-interface, 9-valve, 10-sebific duct A, 11-sebific duct B.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment 1: the utility model provides a kind of pipette Rapid Cleaning and gets liquid servicing unit, its structure as shown in Figure 1, comprise three-way pipe 1, waste liquid collection vessel 2 and negative pressure generator 3, two ports opposing upper and lower are had in described three-way pipe 1, three-way pipe upper port 5 communicates with air, and three-way pipe lower port 6 is connected with flexible rubber interface 8, and described interface 8 is connected with common pipette 4; Be provided with valve 9 in 3rd port 7 of three-way pipe, the 3rd port 7 connects waste liquid collection vessel 2 by flexible pipe A10, and waste liquid collection vessel 2 connects negative pressure generator 3 by flexible pipe B11.
Described negative pressure generator 3 is a kind of small-sized vavuum pumps, and described negative-pressure vacuum pump leads to the work that floor push controls vavuum pump, to liberate both hands.
Use the utility model pipette Rapid Cleaning and get liquid servicing unit, the method for cleaning pipette is: pipette 4 upper port be connected with the interface 8 be connected to below three-way pipe lower port 6; Open valve 9, controlled the vavuum pump work of negative pressure generator 3 by floor push; Now one hand picks up three-way pipe 1, presses three-way pipe upper port 5 with food, makes it seal; Inserted in clear water, cleaning fluid or rinse liquid pipette 4 lower end, because vavuum pump produces the effect of negative pressure, washing lotion is inhaled into pipette, cleans or rinse pipette, and is entered in waste liquid collection vessel 2 by the 3rd port 7 of three-way pipe, sebific duct A10.
The method pipetting required liquid is: cleaning pipette and after rinse, pipette 4 lower port is inserted in the liquid that need pipette, liquid is inhaled in pipette due to negative pressure, when the liquid level in pipette exceedes the scale of aequum, close the valve 9 on the 3rd port 7 of three-way pipe, then by regulating by the forefinger be pressed in three-way pipe upper port 5, put into a certain amount of air and enter pipette, in reduction pipette, liquid level is to the scale needed, pin forefinger, pipette is moved in the vessel accepting solution, unclamp forefinger, liquid in pipette is flowed in vessel along inner wall of utensil, complete and wholely move liquid process.
When same liquid is repeatedly pipetted, only above-mentioned steps need be repeated.
When different liquids is pipetted, first operate by the method for above-mentioned cleaning pipette, then by pipetting the method for required liquid, again pipette being cleaned respectively and after rinse, implementing pipetting of another liquid.
Embodiment 2: the utility model provides a kind of pipette Rapid Cleaning and gets liquid servicing unit, its basic structure is with embodiment 1, and different just described negative pressure generators 3 adopts water-jet type vavuum pump.Current are utilized to produce negative pressure.All the other clean and get the method for liquid with embodiment 1.
Servicing unit of the present utility model coordinates existing pipette to use, highly versatile, and simple to operation, automaticity is high, time saving and energy saving, substantially increases operating efficiency.
