Embodiment 1

A kind of reagent bottle is present embodiments provided, as shown in Figure 1, including glass liner 1 and the bottleneck 2 communicated therewith, such as bottle Neck 2 can be elongated glass tube, further include,

Pass is set to the movable end of bottleneck 2；

Bottle stopper 3 includes suitable for filling in or covering the bottle stopper section closed in pass, set on the face that bottle stopper section is in contact with pass The first sealant is set, the second sealant is set on the face that pass is in contact with bottle stopper section, when bottle stopper slug enters or cover conjunction in bottle When mouth section, the first sealant and the second sealant formation seal section snugly into each other；In the present embodiment, bottleneck 2 fills in pass In, the first sealant is set on the outer wall of bottle stopper section, and the second sealant is set on the inner wall of pass, such as the first sealant It is sprayable on corresponding component with the second sealant；Bottle stopper 3 can be glass stopper；

Graduation mark 4 is set on bottleneck 2, to indicate graduation mark 4 to the accommodating volume between 1 bottom of glass liner.It may be, for example, The different sizes such as 10mL, 25mL, 50mL facilitate experiment to use.

In mentioned reagent bottle, by the way that pass and bottle stopper section is arranged, and the second sealant is set on pass, in bottle stopper The first sealant is set in section, when bottle stopper slug enters or covers conjunction in pass, the first sealant and the second sealant are tight each other Patch forms seal section, solves the problems, such as that storing solution or intermediate fluid are volatilized in the when solvent risen again, not shadow rising again repeatedly Ring the accuracy of its interior liquor capacity；Graduation mark is set on bottleneck again, graduation mark is indicated between 1 bottom of glass liner using the graduation mark Accommodating volume, can directly use after constant volume, quantitative accurate, solution concentration is accurate.

As preferred embodiment, the shape of glass liner 1 is spherical, and inner wall is spherical surface.It is can guarantee by the setting Interior no dead angle, and then ensure that the uniformity of its interior solution concentration, it is final to ensure quantitative and testing result accuracy.

In order to ensure the effect of sealing, prevent solvent from volatilizing, close to graduation mark 4, upper end is close for the lower end of the second sealant The upper end of pass.

Further, the thickness of first sealant is 0.05mm-0.10mm；

The thickness of second sealant is 0.05mm-0.10mm.

In the present embodiment, the first sealant is the first frosted layer, and the second sealant is the second frosted layer, when bottle stopper is filled in Or lid is closed in pass, the first frosted layer is engaged each other with second frosted layer.

In order to fix glass liner, while convenient for placing, as shown in Figure 1, further including body 5, in being adapted with glass liner 1 Chamber, so that glass liner 1 is nested in interior intracavitary and is fixed by it, 5 bottom end of body has a plane, and body 5 is placed to stablize.Body 5 On can indicate volume and temperature.

Such as the shape of body can be cylindric, cubic or halfpace shape, in the present embodiment, body be it is cylindric, Bottom is flat, and can uprightly place will not topple over, and can also consolidate and be positioned on reagent rack or plane cabinet.

Based on the above technical solution, the length of bottleneck 2 is between glass liner 1 and the connection end and its opposite end of bottleneck 2 Away from 2 times or more.On the one hand liquid is not had and is spilt convenient for quantifying in this way；On the other hand it can extend solvent volatilization path, reduce Volatile quantity, preferably 2-3 times.

Preferably, along close to the direction of glass liner 1, the internal diameter of bottleneck 2 gradually increases；Setting can reduce solvent from glass liner in this way Speed in 1 out, while osculum is arranged in upper end, can also reduce volatilization point, improves sealing effect.

As shown in Figure 1, bottleneck 2 is integrally formed with glass liner 1.

Further include knob 6, be set on bottle stopper 3, to take out its pass.
