Description

A kind of separatory funnel

Technical field

The utility model relates to a kind of chemical experimental instrument, especially a kind of separatory funnel.

Background technique

Separatory funnel is common a kind of experimental ware in chemical experiment, is mainly used for extraction, the isolated or purified of substance. It by liquid out of funnel addition funnel suitable for reading, after fulling shake, stands to solution and is layered, according to the original of " flow down upper " when liquid separation Reason opens cock and lower liquid mouth under funnel is allowed all to flow out, and closure piston, supernatant liquid is poured out from suitable for reading.

Existing separatory funnel structure generally comprises under funnel suitable for reading, funnel bucket body, filler neck, funnel cock and funnel Mouthful.But traditional separatory funnel, there are a drawback, mouth is in tiltedly ellipse under funnel and its area is greater than the cross section of filler neck Product, fluid flow are difficult to control, are unfavorable for directly containing isolated liquid in small containers, it is therefore desirable to find a kind of energy Enough solve the problems, such as this separatory funnel.

Utility model content

In view of this, needing to overcome at least one of drawbacks described above in the prior art.The utility model provides one Kind separatory funnel, can effectively solve relevant issues.

The separatory funnel structure includes a kind of separatory funnel characterized by comprising superposed funnel is suitable for reading, Be bound up on the funnel it is suitable for reading under funnel bucket body, positioned at funnel bucket body lower part filler neck and be mounted on the leakage Mouth under the funnel cock and the funnel that struggle against on neck；Mouth is cambered tip under the funnel.

According in the utility model background technique described in the prior art, a kind of separatory funnel used at present, such as Fig. 1 institute Show that there is mouth 105 under funnel suitable for reading 101, funnel bucket body 102, filler neck 103, funnel cock 104 and funnel, mouth under funnel It is greater than the cross-sectional area of filler neck, when containing the liquid isolated in small containers, liquid in oblique ellipse and its area Body flow is difficult to control or need to increase packing step；And funnel disclosed by the utility model, the lower mouth of funnel are cambered Tip, fluid flow can be reduced, easily controllable flow velocity subtracts convenient for directly containing the liquid isolated in small containers Step is dispensed less, makes safe operation, quick.

In addition, also there is following additional technical feature according to separatory funnel disclosed by the utility model:

Further, under funnel mouth radian be in inner concave shape or male type, guarantee the smooth outflow of liquid, lower mouth inner wall without Residual.

Further, open height is 5mm ~ 50mm under funnel, suitable for matching with various sizes of container.

Further, mouth is in smooth circular under funnel, and the liquid convenient for isolating is flowed out from filler neck.

Further, the area of mouth is the 0.2% ~ 95% of filler neck cross section less than the cross-sectional area of filler neck under funnel, Fluid flow, easily controllable flow velocity can be reduced.

The additional aspect of the utility model and advantage will be set forth in part in the description, partially will be from following description In become obvious, or recognized by the practice of the utility model.
