Abstract
The utility model provides a kind of Buchner funnel that conveniently can cut filter paper, described Buchner funnel comprises cylindrical shell (1), infundibular body (2), the filter (3) placing filter paper is provided with at cylindrical shell (1) and infundibular body (2) place, it is characterized in that, metal ring section (4) is set inside the top edge of described cylindrical shell (1); Firmly be stamped on the filter paper of Buchner funnel by endless chipping, filter paper can be made to have and obviously impress vestige, user can cut along impression vestige the filter paper being suitable for this funnel and using easily.The utility model is easy to use, can reduce the probability in the filter paper edge uneven even cutting failure used of cutting Buchner funnel, saves filter paper.
Description
Technical field
The utility model relates to the Buchner funnel that chemical suction filtration uses, and specifically belongs to a kind of Buchner funnel that conveniently can cut filter paper.
Background technology
Many chemical experiments need to carry out suction filtration, and carrying out the modal device of suction filtration is Buchner funnel.Buchner funnel when cutting filter paper often by following steps: 1), by funnel top edge be stained with water; 2), the Buchner funnel with water is tipped upside down on filter paper and make filter paper stay next watermark; 3) along watermark cutting.Owing to being carry out cutting by the watermark be imprinted on filter paper, in process when the process of cutting in cutting, filter paper is wetted, if sharp being not easy to of scissors causes cutting edge uneven, and filter paper has water imbibition, in in watermark to filter paper, hydrosphere can be excessive and cause filter paper cutting too small, cannot suction filtration.Also do not have a kind of instrument or the method that can carry out cutting under non-wetted condition at present, experimenter often can only carry out cutting by experience, and this is extremely unfavorable for the carrying out of testing.
Utility model content
The purpose of this utility model is to provide a kind of Buchner funnel that can facilitate cutting filter paper.
A kind of Buchner funnel that can facilitate cutting filter paper that the utility model provides, comprise cylindrical shell (1), infundibular body (2), the filter (3) placing filter paper is provided with at cylindrical shell (1) and infundibular body (2) place, it is characterized in that, metal ring section (4) is set inside the top edge of described cylindrical shell (1).Firmly be stamped on the filter paper of Buchner funnel by endless chipping, filter paper can be made to have and obviously impress vestige, user can cut along impression vestige the filter paper being suitable for this funnel and using easily.
Another kind of implementation of the present utility model: comprise cylindrical shell (1), infundibular body (2), the filter (3) placing filter paper is provided with at cylindrical shell (1) and infundibular body (2) place, it is characterized in that, the low inside and high outside formation annular incision (4) of top edge of described cylindrical shell (1).
Another implementation of the present utility model: comprise cylindrical shell (1), infundibular body (2), the filter (3) placing filter paper is provided with at cylindrical shell (1) and infundibular body (2) place, it is characterized in that, the top edge of described cylindrical shell (1) in the inner part edge arranges 3-5 small embossment (4).
Described Buchner funnel body is made up of materials such as pottery or glass.
The utility model is easy to use, can reduce the probability of the uneven even cutting in the edge failure when the filter paper that cutting Buchner funnel is used, saves filter paper.
The utility model tool has the following advantages:
The utility model structure is simple, easy to use, impresses, be beneficial to filter paper and cut under can be implemented in dry condition to filter paper.The utility model can reduce the probability of the uneven even cutting in the edge failure when the filter paper of cutting Buchner funnel.

Detailed description of the invention
A kind of Buchner funnel that conveniently can cut filter paper as shown in Figure 1, comprise cylindrical shell (1), infundibular body (2), be provided with the filter (3) placing filter paper at cylindrical shell (1) and infundibular body (2) place, metal ring section (4) is set inside the top edge of cylindrical shell (1).Firmly be stamped on the filter paper of Buchner funnel by endless chipping, filter paper can be made to have and obviously impress vestige, user can cut along impression vestige the filter paper being suitable for this funnel and using easily.
Another kind of implementation: the top edge of cylindrical shell (1) can be designed to low inside and high outside annular incision (4), see Fig. 2.
Another implementation: can by the top edge of cylindrical shell (1) in the inner part edge 3-5 small embossment (4) is set.
Above-mentioned embodiment all can realize that filter paper is had and obviously impress vestige, and user can cut along impression vestige the filter paper being suitable for this funnel and using easily.Effectively can reduce the probability of the uneven even cutting in the edge failure when the filter paper of cutting Buchner funnel.
