It is selectively adsorbed, desorbs when solid phase filler, to realize the separation, purifying and enrichment to sample, be finally reached purification and mention
Pure sample component to be measured, the purpose for reducing sample substrate interference, improving detection sensitivity, belong to the novel skill in agriculture test
Art, but corresponding use for laboratory Solid Phase Extraction frame type is seldom, and structure is complicated, exists and manufactures difficult, higher cost,
The problems such as more troublesome is used, also has corresponding extraction frame to disclose in the prior art, but using effect is undesirable, because
This provides a kind of more applicable Solid Phase Extraction and puts up as urgent problem to be solved.
Summary of the invention
The utility model fills up prior art blank, provides a kind of completely new Solid Phase Extraction frame, including support arm and from
Heart pipe support, the support arm upper inner are provided at least one set of extraction column holder, and support arm lower inside is provided with centrifugation
Pipe support, is provided with sliding slot on the inside of the support arm in side wall, the centrifuge tube shelf two sides are provided with detachable sliding block, on sliding block
It is provided with plunger；Moving left and right for centrifuge tube shelf can be achieved using the Solid Phase Extraction frame of this structure, while it can also be adjusted
Vertical height facilitates experimenter to dismantle and clean, meets the requirement of Solid Phase Extraction.
The specific technical solution of the utility model is as follows:
A kind of Solid Phase Extraction frame, including support arm and centrifuge tube shelf, the support arm upper inner are provided at least one
Group extraction column holder, support arm lower inside are provided with centrifuge tube shelf, are provided with sliding slot in side wall on the inside of the support arm, institute
It states centrifuge tube shelf two sides and is provided with detachable sliding block, be provided with plunger on sliding block；
The sliding slot is made of upper hopper chute and gliding groove, and the upper hopper chute is connected with gliding groove two sides by annular groove；
The centrifuge tube shelf is divided into upper layer and lower layer, and the upper layer is provided at least two rows of centrifugation pores, and lower layer is provided with and centrifuge tube
The corresponding tapered blind hole in hole；The side of the centrifuge tube shelf is connected with handle by bracket；
The detachable sliding block is flexibly connected with centrifuge tube shelf two sides side wall, can pass through screw thread or other flexible connection sides
Formula connection；The plunger size and sliding slot internal diameter are adapted；The upper hopper chute, gliding groove are identical with the internal diameter of annular groove；Institute
It states extraction column holder and is provided with several extraction post holes corresponding with centrifuge tube hole site；
Using the Solid Phase Extraction frame of this structure, solid-phase extraction column is passed through into extraction post holes insertion extraction column holder when use
In, in order to guarantee its stability, generally require setting two groups of extraction column holders up and down；Solution after extraction will be used to installing later
Centrifuge tube is placed on centrifuge tube shelf by being centrifuged pore, and the lower end of centrifuge tube is placed in tapered blind hole to realize centrifuge tube
It is firm；Since centrifuge tube shelf upper layer is provided at least two rows of centrifugation pores, two rows of centrifuge tubes, experimenter can be placed simultaneously
The back-and-forth motion of centrifuge tube shelf may be implemented by pull handle, thus two rows of centrifuge tubes can be made to install identical extraction respectively
Liquid is taken, to provide control group, two groups of extraction conditions is identical with environment, it is ensured that the accuracy of experiment；
Sliding slot is made of upper hopper chute and gliding groove, and the upper hopper chute is connected with gliding groove two sides by annular groove, upper cunning
The setting of slot and gliding groove is directed to the various sizes of extraction column branch so that the vertical range of centrifuge tube realizes adjustable in this way
Frame can be preferably adapted to；And connected by annular groove, it both ensure that the smooth degree of gliding groove connection, simultaneously because annular
The presence of sliding slot, experimenter can allow centrifuge tube shelf to move in a circle in the annular groove, can thus make centrifuge tube
Interior liquid preferably disperses, and does not need to carry out the operations such as vibration dispersion after taking out centrifuge tube again, saves the time；It simultaneously can
Disassembly sliding block is flexibly connected with centrifuge tube shelf two sides side wall, and various sizes of centrifuge tube shelf can be replaced in this way, improve and set
Standby versatility saves the use cost of equipment.
It is moved left and right in conclusion centrifuge tube shelf can be achieved using the Solid Phase Extraction frame of this structure, while can be with
Its vertical height is adjusted, facilitates experimenter to dismantle and clean, meets the requirement of Solid Phase Extraction.
