Abstract
The utility model discloses a device used for chemical analysis and pipetting, in particular to a pipette suction-prevention device. The pipette suction-prevention device comprises a base for placing vessels. An upright pole is arranged on the base and is provided with a clamp which can move up and down along the upright pole and can be fixed at any height in clamping mode. The pipette suction-prevention device has the advantages that the clamp which can be moved and be positioned is arranged on the upright pole, the upper end position of a pipette can be marked through the clamp in a pipetting process, and the suction phenomenon due to the fact that an operator needs to observe the volume of the pipetted liquid at the upper portion of the pipette in the pipetting process and cannot observe whether the sharp opening of at the lower end of the pipette breaks away from the liquid surface is avoided; and a groove arranged on the base can be used for placing an ampoule bottle to provide convenience for pipetting of fluid inside the ampoule bottle.
Description
Technical field
The utility model relates to the device that a kind of chemical analysis pipetting is used, specifically a kind of anti-pipette suction device.
Background technology
The method that quantitatively pipettes at present liquid in chemical analysis is mainly finished by pipette, concrete flow process is: at first pipette is inserted liquid internal to be pipetted, and then pinch flat ear washing bulb with one and aim at the suitable for reading of pipette, the negative pressure that flat ear washing bulb inside is pinched in utilization makes pipette top vacuum occur the liquid of pipette bottom is entered in the pipette, thereby reaches the purpose that pipettes liquid.
In practical operation, because pipette is generally longer, operating personnel's sight line often will notice that the graduation mark on pipette top is quantitatively to pipette liquid in pipetting the liquid process, in this process owing to can't take into account the lower end sharp-crested of pipette, tend to make the lower end sharp-crested to break away from the liquid level that will pipette liquid, extraneous air will enter pipette and cause the suction phenomenon under the effect of pipette top negative pressure at this moment; The efficient that appearance suction phenomenon can affect pipetting on the one hand causes repeatedly pipetting, also enters ear washing bulb inside for vacuum will cause the liquid that pipettes owing to pinching flat ear washing bulb inside on the other hand, pollutes ear washing bulb.If when the liquid that will pipette in addition is less, thereby owing to can waste the phenomenon that partially liq causes remaining liquid to pipette in the suction process.
Summary of the invention
Technical problem to be solved in the utility model just is to pipette the defective that can occur suction in the liquid process for existing pipette, provides a kind of pipette that prevents the anti-pipette suction device of suction to occur.
In order to solve the problems of the technologies described above, anti-pipette suction device of the present utility model includes the base of placing container, is provided with a vertical rod on the base, is provided with the clip that can move up and down and can grip at arbitrary height along vertical rod in the vertical rod.
Also have the groove that to place ampoule bottle on the container placement surface of described base.
After adopting above-mentioned structure, owing to being provided with the clip removable and location in the vertical rod, can in the pipetting process, utilize clip that the pipette upper end position is indicated, avoid in moving the liquid process pipetting the volume of liquid and can't taking into account the phenomenon whether pipette lower end sharp-crested breaks away from the suction that liquid level causes owing to operating personnel need to observe pipette top; The groove that arranges on the base can be used for settling ampoule bottle, has made things convenient for the ampoule bottle inner fluid is carried out pipetting.
Description of drawings
Fig. 1 is the structural representation of the anti-pipette suction device of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, anti-pipette suction device of the present utility model is described in further detail.
As shown in the figure, anti-pipette suction device of the present utility model, the base 2 that comprises placing container 1, be provided with groove 8 on the base, larger container can be placed on the placement surface of base (such as Fig. 1), and can be placed in the groove 8 for the ampoule bottle that is difficult for steadily settling, avoid occurring overturning or the phenomenon of toppling; Base 2 tops are provided with a vertical rod 3, are provided with the clip 4 that can move up and down and can grip at arbitrary height along vertical rod 3 in the vertical rod 3.Also comprise the pipette 6 that can draw the solution 5 in the container 1, pipette 6 tops are provided with the ear washing bulb suitable for reading 7 of an aligning pipette 6.
Use procedure is as follows:
When carrying out pipetting, the container 1 that will pipette solution 5 is placed on the base 2, pipette 6 is inserted in the container 1, when the lower end sharp-crested of observation pipette 6 soon arrives container bottom, unclamp the clip 4 on vertical rod 3 tops, the upper port of clip 4 with pipette 6 flushed, then clip 4 is clamped in the vertical rod 3, so just can indicate the position of pipette 6, the upper port that needs only pipette 6 in pipetting solution 5 processes is no more than the position that clip 4 is indicated, because the lower end sharp-crested of pipette 6 is in the position near container 1 bottom, so the lower end sharp-crested can not break away from liquid level, the phenomenon of suction just can not occur yet.In moving the liquid process because operating personnel's sight line mainly concentrates on the top of pipette 6 will pipette solution 5 with observation post volume, therefore operating personnel are the positions that can take into account vertical rod 3 upper clamp 4, can guarantee not allow the upper port of pipette 6 surpass the position that clip 4 is indicated, thereby can avoid the appearance of suction phenomenon.
Claims (2)
