Description

A kind of solid-phase extraction device

Technical field

The utility model relates to a kind of Laboratory Instruments, refers in particular to use a kind of solid-phase extraction device that solid phase extraction techniques is separated, purified target substance or concentrates.

Background technology

At present, the solid-phase extraction device that the laboratory is used, solid-phase extraction device as brands such as widely used Waters, SUPELCO, Mediwax, JT-BAKER, be to utilize a casing and fixed head, casing is connected with vacuum extractor by pipeline, is provided with a lot of standard extraction pillar connectors (12 or 24) on fixed head, during use fixed head is placed on the casing, start vacuum extractor, vacuum swabbing action extracts; The problem that this device exists is: the sealing between casing and the fixed head is bad, and poor stability makes to be difficult to reach the vacuum that needs in the casing; Simultaneously, inhomogeneous to the suction of each extraction connector, the part pillar is very fast, the part pillar is slow, is difficult to reach consistent, influences the accuracy of effect of extracting and experiment.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, rate of extraction high conformity, control easy to adjust, can support a kind of solid-phase extraction device of each operating procedure of SPE operation preferably.

The purpose of this utility model is achieved in that a kind of solid-phase extraction device, comprise housing, wherein: described case top is provided with a plurality of standard solid-phase extraction pillar connectors, in housing, be provided with multi-channel peristaltic pump, the number of channels of this multi-channel peristaltic pump is consistent with the standard solid-phase of case top extraction pillar connector quantity: each standard solid-phase extraction pillar connector is connected with a pump orifice of multi-channel peristaltic pump respectively by pipeline, and each outlet of multi-channel peristaltic pump leads to housing by pipeline and is connected with pipe connections respectively outward; On housing, be provided with control panel.

Housing front portion described in above-mentioned a kind of solid-phase extraction device is provided with panel easy to assemble, and panel easy to assemble is fixedlyed connected with housing by screw; Be provided with support on panel easy to assemble, be provided with the holddown groove identical with pipe connections quantity at the support front end, pipe connections is plugged in this holddown groove.

Case top described in above-mentioned a kind of solid-phase extraction device is provided with six to 38 standard solid-phase extraction pillar connectors.

The utility model is fixed on case top by standard solid-phase being extracted the pillar connector, and is connected with a pump orifice of multi-channel peristaltic pump respectively after adopting said structure, and is simple in structure, can guarantee the sealing of each standard solid-phase extraction pillar; The rotating speed and the flow velocity of multi-channel peristaltic pump are good linear relationship, and extracting operation is carried out under stable environment, guarantee the effect of extraction, and can regulate pumping velocity easily by control panel as required; Simultaneously, be connected with pipe connections by each outlet with multi-channel peristaltic pump, pipe connections can be connected with malleation wash-out water conservancy diversion joint, realizes the malleation of standard solid-phase extraction pillar wash-out at the uniform velocity, thereby support each step of SPE operation fully, use convenient.

Description of drawings

Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.

Fig. 1 is the perspective view of a kind of specific embodiment of the utility model;

Fig. 2 is one of user mode schematic diagram of the present utility model;

Fig. 3 is two of a user mode schematic diagram of the present utility model.

Among the figure: 1-housing, 2-standard solid-phase extraction pillar connector, 3-multi-channel peristaltic pump, 4-pipe connections, 5-control panel, 6-panel easy to assemble, 7-support, 8-holddown groove, 9-malleation wash-out water conservancy diversion joint.

The specific embodiment

Consult Fig. 1, shown in Figure 2, a kind of solid-phase extraction device of the present utility model, comprise housing 1, be provided with eight standard solid-phase extraction pillar connectors 2 at housing 1 top, in housing 1, be provided with digital multi-channel peristaltic pump 3, the number of channels of this multi-channel peristaltic pump 3 is eight, and is consistent with standard solid-phase extraction pillar connector 2 quantity at housing 1 top; Each standard solid-phase extraction pillar connector 2 is connected with a pump orifice of multi-channel peristaltic pump 3 respectively by pipeline, and each outlet of multi-channel peristaltic pump 3 leads to outside the housing 1 by pipeline and is connected with pipe connections 4 respectively; Be provided with panel 6 easy to assemble in housing 1 front portion, panel 6 easy to assemble is fixedlyed connected with housing 1 by screw, is easy to remove and repair and changes tube connector; Be provided with support 7 on panel 6 easy to assemble, be provided with eight holddown grooves 8 identical with pipe connections 4 quantity at support 7 front ends, pipe connections 4 is plugged in this holddown groove 8, can be convenient for changing discharging tube like this or is connected with malleation wash-out water conservancy diversion joint; On housing 1, be provided with control panel 5, be used to control the running of multi-channel peristaltic pump 3.

When the utility model specifically uses, consult shown in Figure 2, standard solid-phase is extracted pillar to be plugged on each connector 2, add various solution and sample to be extracted set by step, select suitable pumping velocity can carry out extracting operation by control panel 5 as required, use very simply, convenient, and it is steadily consistent respectively to extract the pumping velocity of connector 2.
