Description
Technical field
The utility model is related to a kind of Buchner funnel more particularly to a kind of multistage Buchner funnels.
Background technology
Buchner funnel is a kind of common filter plant in laboratory, usually forms Suction filtration device with vacuum pump and bottle,suction,
It can be using vacuumizing or negative pressure is quickly filtered.But traditional filtered on buchner funnel equipment is only used for solution
Filtering, and can not achieve and detach the solute in solution while filtering, while some solution composition complexity are easy to make
Aluminium film block, even if select different pore size membrane filtration but if will by several times be filtered step by step, when not only needing longer operation
Between, and filtrate can cause centainly to lose in transfer process.
Disclosed in Chinese patent literature " a kind of multistage Buchner funnel ", notification number CN202569719U, bulletin
Day is on December 5th, 2012, and this application discloses a kind of multistage Buchner funnels, by Buchner funnel ontology and both sides disposed thereon
Parallel barrier piece is constituted, and while once being filtered sample to be filtered, crossing Buchner funnel with multistage can be easily
Different size of molecule in filtered sample is detached, compared with usually being filtered the filter effect that could be realized several times
Greatly shorten the operating time.The shortcoming of the utility model is that the installing and dismounting of barrier piece is difficult inconvenient.
Utility model content
In order to overcome the shortcomings of that multistage Buchner funnel handling in the prior art are inconvenient, the utility model provides a kind of handling
Convenient multistage Buchner funnel, the filter are not only suitable for mobile phase when the chemical analyses such as high performance liquid chromatography, gas-chromatography
Remove particle and degassing filter, and can also according to requirement of experiment to the particulate matter in filtered sample by molecular size carry out by
Grade separation.
To achieve the goals above, the utility model uses following technical scheme：
A kind of multistage Buchner funnel, including Buchner funnel ontology and setting are in intrinsic first filtering of the Buchner funnel
Tube filler, first filter core cartridge are threadedly coupled with the Buchner funnel ontology, and first filter core cartridge bottom surface is equipped with several
The hole penetrated for filtrate.
First filter core cartridge can both form sealing structure with Buchner funnel ontology by helicitic texture, can also be easily
Dismounting, can be carried out at the same time separation by the substance of different molecular size in filtered sample, be lost caused by avoiding filtrate from shifting, greatly
Filtration time is saved greatly, improves efficiency.
As a kind of optimal technical scheme of the utility model, the bottom edge of first filter core cartridge is equipped with a circle and falls
Angle.The edge of filter paper in Buchner funnel ontology is just pushed down in the bottom of first filter core cartridge, and the purpose that chamfering is arranged is to prevent from filtering
Paper is damaged.
As a kind of optimal technical scheme of the utility model, the second filter core cartridge is equipped in first filter core cartridge,
Second filter core cartridge is threadedly coupled with first filter core cartridge, and second filter core cartridge bottom surface is equipped with several for filtrate
The hole of transmission.The internal thread structure of first filter core cartridge can be combined into multistage filtering structure with the second filter core cartridge.
As a kind of optimal technical scheme of the utility model, the diameter of the first filter core cartridge bottom hole is less than described
The diameter of second filter core cartridge bottom hole.
As a kind of optimal technical scheme of the utility model, first filter core cartridge and second filter core cartridge top
Portion is respectively equipped with spacing ring.
As a kind of optimal technical scheme of the utility model, first filter core cartridge and second filter core cartridge top
Portion is respectively equipped with a pair of symmetrically arranged limited block.
As a kind of optimal technical scheme of the utility model, the outer surface of the spacing ring or the limited block, which is equipped with, rubs
Wiping portion.
The advantageous effect that the utility model is reached compared with prior art is：Using removable multistage Buchner funnel, energy
It is enough that the substance of different molecular size in filtered sample is carried out at the same time separation according to requirement of experiment, it is damaged caused by avoiding filtrate from shifting
It loses, filtration time is greatly saved, improves efficiency；Simultaneously as Buchner funnel ontology and filter core cartridge and filter structure energy
Enough separation, can easily clean it.The utility model has simple in structure, easy to operate, easy cleaning, can be multistage same
When the characteristics of filtering.
