Abstract
The utility model relates to a kind of sample loading device for column chromatography, is made up of piston, empty cylinder, back-up ring.There is plug handle at described piston rear portion, and piston can coordinate with wall slip in empty cylinder; Fluid pore is had at the bottom of described empty cylinder cylinder; Described shield ring sleeve, outside empty cylinder, is made up of back-up ring ring and back-up ring bar, back-up ring ring is also provided with screwed hole, by clamping screw, back-up ring ring is fixed on empty cylinder.The utility model controls empty cylinder falling head by back-up ring, stably frame flat bottom empty cylinder, on the medium bed surface in chromatographic column, is added to medium upper surface with making fluid sample accurate stable, avoids the separating medium of disturbing good dynamic balance, improves experiment effect.
Description
Technical field
The utility model relates to laboratory services, is specifically related to a kind of sample loading device for column chromatography.
Background technology
The utility model is mainly used in Food Science, life science, chemical and environmental science, column chromatography is one of Main Means of isolated or purified organic or inorganic thing, utilize the difference of each component physical property, carried out being separated and measuring by multicomponent mixture, the medium of sharing of use has macroreticular resin, silica gel, sephadex etc. multiple.Carry out in chromatography operating process, sample to be separated should be uniformly distributed on the dielectric surface balanced during application of sample.Conventional loading methods drips along chromatographic column inwall with after glue head dropper or pipettor pipette samples, and due to the difference of manual operation, the bed surface that particularly medium is formed has certain distance with chromatographic column mouth, sample drop after falling media plane often impact media plane cause eddy current, thickness homogeneous sample layer can not be formed after application of sample, experimental implementation poor stability, the accuracy of impact experiment.
Summary of the invention
The utility model provides a kind of sample loading device for column chromatography for solving prior art problem, can stablize and complete column chromatography loading exactly.
The technical solution of the utility model is as follows: a kind of sample loading device for column chromatography, is made up of piston, empty cylinder, back-up ring.It is characterized in that: there is plug handle at described piston rear portion, piston can coordinate with wall slip in empty cylinder, and described shield ring sleeve is outside empty cylinder.
Multiple fluid pore is had at the bottom of described empty cylinder cylinder.
Described back-up ring is made up of back-up ring ring and back-up ring bar, and back-up ring ring set is outside empty cylinder, and back-up ring bar is fixed on outside back-up ring ring in pairs.
Described back-up ring ring is also provided with screwed hole, by the clamping screw of correspondence, back-up ring ring is fixed on empty cylinder.
The beneficial effect of the technical program: can back-up ring bridge to the upper brim of chromatographic column along upper, allow fluid sample is housed empty cylinder bottom drop to dielectric surface in post reposefully, empty cylinder is fixed by clamping screw, by gently pressing piston handle, piston is pushed to dielectric surface the sample in empty cylinder equably by fluid pore.

Fig. 1 is the utility model structural representation.
In figure, 1, piston handle; 2, piston; 3, back-up ring bar; 4, back-up ring ring; 5, clamping screw; 6, screwed hole; 7, empty cylinder; 8, fluid pore.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of sample loading device for column chromatography of the present utility model, is made up of piston, empty cylinder, back-up ring.As shown in Fig. 1, it is characterized in that: there is plug handle 1 at described piston rear portion, and piston 2 can coordinate with wall slip in empty cylinder 7, and described shield ring sleeve is outside empty cylinder.
Multiple fluid pore 8 is had at the bottom of 7, described empty cylinder.
Described back-up ring is made up of back-up ring ring 4 and back-up ring bar 3, and back-up ring ring 4 is enclosed within outside empty cylinder 7, and back-up ring bar 3 is fixed on outside back-up ring ring 4 in pairs.
Described back-up ring ring is also provided with screwed hole 6, by the clamping screw 5 of correspondence, back-up ring ring 4 is fixed on empty cylinder 7.
The beneficial effect of the technical program: can back-up ring bar 3 frame to the upper brim of chromatographic column along upper, allow fluid sample is housed empty cylinder 7 bottom drop to dielectric surface in post reposefully, empty cylinder 7 is fixed by clamping screw 5, by gently pressing piston handle 1, piston 2 is pushed to dielectric surface the sample of 7 li, empty cylinder equably by fluid pore 8.
