Abstract
The utility model discloses a novel automatic suction-discharge type calibrated suction pipe capable of preventing excessive suction, belonging to the field of chemistry apparatus. The calibrated suction pipe comprises a main pipe with scales, wherein the upper end opening is sheathed with a syringe with corresponding capacity; a liquid storage groove is arranged above the scales of the main pipe; a side pipe is arranged at one side above the liquid storage groove of the main pipe and connected with a rubber soft pipe; the rubber soft pipe is provided with a flow control valve; the rubber soft pipe can generate a gap by adjusting the flow control valve and then air gets in and out from the gap so as to carry out micro-adjustment on the liquid in the main pipe; and the operation is safe and reliable, and simple and fast.
Description
Technical field:
The present invention relates to liquid getting device tool commonly used in the laboratories, field such as a kind of chemical industry, scientific research, teaching, relate in particular to a kind of novel anti-suction and cross automatic suction type measuring pipette.
Background technology:
Measuring pipette is to carry out glass wares commonly used in chemical analysis and the experimental work at present, it is usually used in quantitatively pipetting all ingredients solution in chemical analysis, and the specification of measuring pipette has 0.1ml, 0.2ml, 0.5ml, 1ml, 2ml, 5ml, 10ml, 15ml, 20ml, 25ml, 50ml etc.At present, common measuring pipette mostly is the straight shape glass tube of up/down perforation in the experimental implementation, insert the upper port imbitition of measuring pipette during use by rubber pipette bulb, because the effect of pipe inside and outside differential pressure, liquid is promptly entered in the pipe by measuring pipette lower end sharp-crested, when getting the liquid height and be higher than required scale 2-3cm, take away rubber pipette bulb and block the mouth of pipe with forefinger, slowly reduce liquid level to required scale by moveable finger.The problem that existing method exists is: inconvenient operation, it is wayward to get liquid measure, and operator's technical merit is had relatively high expectations.When imbibition,, pollute rubber pipette bulb, cause the waste of reagent usually because operator's undue force sucks liquid in the rubber pipette bulb; In the process of transferring liquid level, draw again owing to operate unskilled often the needs.Patent 200420070531.X discloses a kind of anti-suction pipe of inhaling, and the reservoir that utilizes suction pipe top has played the effect of a buffering to the solution of imbibition surplus, prevents that effectively the imbibition surplus is to rubber pipette bulb.Shortcoming is, is in the measuring pipette imbitition process below the 5ml for specification, because measuring pipette top suction inlet internal diameter is very little, is difficult for accurately aiming at rubber pipette bulb, and inconvenient operation also causes the vessel that hold solution to topple over sometimes.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency that exists in the existing measuring pipette, provides a kind of novel anti-suction to cross automatic suction type measuring pipette, can guarantee the convenience of imbibition, transfers the accuracy of liquid, the agility of tapping.Manipulate simply, greatly reduce specification requirement the operator.
The utility model is to finish by following technical proposal: automatic suction type measuring pipette is crossed in a kind of novel anti-suction, the person in charge who comprises band scale on it, it is characterized in that the described syringe of being responsible for the corresponding volume of upper end port socket, syringe passes through the one-shot forming of FIxed abrasive article high temperature with the person in charge.Be responsible for 1cm-2cm place, scale the top and be provided with a reservoir, reservoir top one side is provided with side pipe, connect rubber hose on the side pipe, flow control valve is housed on the rubber hose, by adjusting flow control valve, allow rubber hose produce the slit, make air through the turnover of place, slit, thereby the liquid in being responsible for is carried out trace adjustment, with the adjustment of accurate control liquid level.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
(1) cushion space of reservoir has avoided the imbibition surplus to enter rubber pipette bulb, has avoided the waste of reagent and the pollution of rubber pipette bulb; (2) use of syringe has increased the simplification of imbibition process, has solved the drawback that can't aim at because of the too thin rubber pipette bulb of measuring pipette upper end suction inlet; (3) use of flow control valve on the rubber hose, solution in being responsible for can not flowed out automatically from the mouth of pipe, be responsible for thereby move easily, in addition by the slit in the flow control valve adjustment rubber hose, allow air through the slit turnover person in charge, thereby the liquid in being responsible for is carried out trace adjustment, with accurate control liquid outflow amount.
Description of drawings:
Accompanying drawing 1: the utility model master TV structure schematic diagram
Number among the figure: 1. syringe, 2. reservoir 3. is responsible for, 4. rubber hose, 5. flow control valve, 6. roller, 7. tiltedly rail, 8. wedge shape race, 9. side pipe
The specific embodiment:
As shown in Figure 1, the measuring pipette of this example has the person in charge 3 of a scale of band on it, be responsible for the syringe 1 of 3 the corresponding volume of upper end port socket, be responsible for 1cm-2cm place, scale top and be provided with a reservoir 2, reservoir top one side is provided with side pipe 9, side pipe 9 ports connect rubber hose 4, installing flow control valve 5 on the rubber hose 4, by adjusting the roller 6 on the flow control valve 5, make rubber hose 4 produce the slit, make air through the turnover of place, slit, thereby the liquid of being responsible in 3 is carried out trace adjustment, with the adjustment of accurate control liquid level.
As shown in Figure 1, in the present embodiment, flow control valve 5 has adopted the medical infusion regulator commonly used of, and it has a wedge shape race 8 and is installed in the wedge shape race 8 and the roller 6 that can roll along the oblique rail 7 of wedge shape race 8.Rubber hose 4 is contained between the perpendicular wall in right angle of roller 6 and wedge shape race 8.During imbibition roller 6 is slided into Far Left, rubber hose 4 sealings this moment with syringe 1 imbitition, after absorption is enough, is slowly regulated roller 6 and are slided to the right, thereby guarantee the degree of accuracy that liquid level is adjusted.
