Abstract
The utility model discloses a module for rapid replacement of column inserted rods. The module comprises an extraction tube, a switchover head, a branch pipe and a lower sealing screw. External threads are formed on the outer side of the upper end of the switchover head and the outer side of the lower end of the switchover head respectively. The upper end of the switchover head is in threaded connection with a solid-phase extraction instrument. The lower end of the switchover head is in threaded connection with the branch pipe. The extraction tube is mounted in the branch pipe and the switchover head. The upper end of the extraction tube and the upper end of the switchover head are mounted in a sealed mode. The lower end of the extraction tube and the lower end of the branch pipe are mounted in a sealed mode. A lower opening of the extraction tube is sealed with the lower sealing screw. By means of the module, the column inserted rods with different specifications can be replaced quickly and easily on the same solid-phase extraction instrument.
Description
Technical field
The utility model relates to a kind of post inserted link, refers in particular to a kind of quick-replaceable post inserted link module.
Background technology
In prior art, the post inserted link of solid-phase extracting instrument is generally integral type, be divided into 1ml, 3ml, 6ml and 12ml etc., and between post inserted link and solid-phase extracting instrument, be monolithic construction, in the time of need to changing different post inserted link, parts need to be dismantled one by one, be changed and need specification post inserted link, its complex operation and easily makeing mistakes, and the parts that remove are divided into a plurality of findings, easily obscure and easily lose.
In view of the described defect of prior art solid-phase extracting instrument post inserted link, the inventor furthers investigate, and develops a kind of quick-replaceable post inserted link module that overcomes described defect, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of quick-replaceable post inserted link module, realizes between the post inserted link of different size on same solid-phase extracting instrument fast, provides for simple replacement of.
For reaching above-mentioned purpose, solution of the present utility model is:
A quick-replaceable post inserted link module, comprises extracting tube, adapter, arm and lower seal screw; Outside, adapter upper end and outside, lower end are formed with respectively external screw thread, and upper end and solid-phase extracting instrument are spirally connected, and lower end and arm are spirally connected; Extracting tube is arranged in arm and adapter, and upper end and the sealing of adapter upper end are installed, and lower end and the sealing of arm lower end are installed, and the lower ending opening of extracting tube seals by lower seal screw.
On described arm lateral wall, sealing ring is installed, sealing circle is " O " RunddichtringO.
Described extracting tube is teflon pipe.
Install by conical gasket and the sealing of adapter upper end described extracting tube upper end, and install by conical gasket and the sealing of arm lower end extracting tube lower end.
Adopt after such scheme, the utility model is installed while changing, conventionally at solid-phase extracting instrument, a common interface is set, this common interface mates with adapter, the post inserted link of different size is designed to the adapter of same specification and the common interface of solid-phase extracting instrument docks, only need screw off adapter, change the new post inserted link of different size and screw adapter, simple to operate, reliable, same post inserted link joint can be repeatedly used, guaranteed sealing, simultaneously easy to use.
