The external screw thread that screw thread matches, the core is located between the core pallet and core retainer ring.
It is preferred that technical scheme, the bottom of the upper chromatographic column is provided with upper flange, and the upper end of the lower chromatographic column is provided with down
Flange, the upper flange is identical with the diameter of lower flange, the upper end connection upper flange of the core pallet, bottom connection laxative remedy
Orchid, the top and bottom of core pallet side wall are respectively along the groove that is circumferentially with of core pallet side wall, and the groove is interior provided with O-shaped
Circle.
It is preferred that technical scheme, during the core is glass core, filter cloth, stainless steel filtering net, polytetrafluoroethylene diaphragm
It is a kind of.
It is preferred that technical scheme, the upper chromatographic column, lower chromatographic column, core pallet, core retainer ring are by polytetrafluoroethyl-ne
Alkene is made.
It is preferred that technical scheme, the upper flange is bolted to connection with lower flange.
The upper chromatographic column of core changeable type glass chromatography column of the present utility model and lower chromatographic column are by upper flange with
Filter is fixed between the two by flange, is carried out between filter and upper chromatographic column, lower chromatographic column by O-ring close
Envelope, it is to avoid polluted to material using vacuum grease or vaseline.Appointing in upper chromatographic column, lower chromatographic column and filter
A meaning part is damaged, and only need to change broken parts, improve the utilization rate of glass chromatography column, reduces glass chromatography
The use cost of post.By changing the core in filter, it is possible to achieve material of the same glass chromatography column to different-grain diameter
Filtration needs, increase the use scope of glass chromatography column.
