Description

Trace sample injection vial

Technical Field

The utility model relates to a trace advances kind small bottle.

Background

In sample analysis and detection in different fields of food, biology and the like, a target to be detected is often required to be placed in an analysis vial in a solution form for chromatographic detection, a conventional sample injection vial is mainly made of glass, the sample loading capacity is 0.5-1.5 mL, when the sample is in a trace constant volume, the sample volume is often only 20-200 muL, and at the moment, an inner cannula is required to be added in the conventional glass vial to realize trace sample injection. After the inner insert tube is added for sample injection, the sample injection small bottle made of glass materials is consumed except for the inner insert tube in one sample injection, and the cost of micro sample injection is increased. Moreover, the bottle caps of the prior sampling vials are in threaded connection, require screwing, are inconvenient to operate and take a long time.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a trace advances kind small bottle to minimum experiment consumption accomplishes trace and advances kind process and easy operation swiftly.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model provides a trace advances kind small bottle, includes the bottle, the bottle top is provided with the bottle lid, the top of bottle is under the narrow round platform shape of width, bottle lid week side be with under the narrow round platform cover of the top adaptation of bottle, the bottle lid with bottle plug-in type close-fitting connection, the bottle adopts the polypropylene material to make.

Furthermore, an inner insertion tube is arranged in the bottle body.

Furthermore, the inner inserting tube is made of polypropylene materials.

Furthermore, the outer periphery side of the top end of the inner inserting tube is provided with a folded edge, and the width of the folded edge is not larger than the wall thickness of the top end opening of the bottle body.

Further, the round table sleeve is a rubber sleeve or a silica gel sleeve.

Furthermore, the circular table sleeve and the bottle cap are of an integral structure made of the same material.

Further, the circular table sleeve is adhered in the bottle cap.

Compared with the prior art, the utility model discloses a beneficial technological effect:

the bottle body and the bottle cap are in plug-in type close-fitting connection in a round platform structure, and the operation is fast and convenient. Meanwhile, the sample injection device is made of polypropylene materials, so that the cost is greatly reduced, and the trace sample injection process is completed with lower experimental consumption.

Detailed Description

As shown in fig. 1 to 4, a micro sample injection vial comprises a vial body 1, wherein a vial cap 2 is arranged at the top end of the vial body 1, the top end of the vial body 1 is in a truncated cone shape with a narrow top and a wide bottom, a truncated cone sleeve 3 with a narrow top and a wide bottom is arranged on the inner peripheral side of the vial cap 2 and is matched with the top end of the vial body 1, the vial cap 2 is connected with the vial body 1 in a plug-in type tight fit manner, an inner insertion tube 4 is arranged in the vial body 1, a folded edge 401 is arranged on the outer peripheral side of the top end of the inner insertion tube 4, the width of the folded edge 401 is not greater than the wall thickness of an opening at the.

In this embodiment: the round table sleeve is a rubber sleeve or a silica gel sleeve, and is bonded in the bottle cap.

In another embodiment, the circular truncated cone sleeve and the bottle cap 2 are of an integral structure made of the same material.

The utility model discloses a bottle lid 2 is convenient, swift with 1 adaptation of bottle connection, and the bottle is the polypropylene material with interior intubate moreover, reduces the experiment cost consumption at the trace sampling in-process.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
