Description

Split type concentrator tube

Technical Field

The utility model belongs to the detection field especially relates to a split type concentrator tube.

Background

The existing KD concentration pipe, nitrogen blowing pipe, automatic concentration pipe (with scale tail pipe) and the like all need multi-stage transfer during concentration, which can cause the loss of substances to be measured, inaccurate constant volume, repeated cleaning, increase of solvent consumption, influence of impurities in the solvent on measurement and the like.

Disclosure of Invention

Technical problem to be solved

For solving the problem that prior art exists, the to-be-solved problem of the utility model is to provide a split type concentrator tube, multistage transfer when solving concentration, the constant volume is inaccurate, the good abluent difficult problem of integral type concentrator tube tail pipe.

(II) technical scheme

In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a split type concentrator tube, the concentrator tube includes concentrated dress liquid pipe and ampoule, its characterized in that: the concentrated liquid containing pipe is connected with the ampoule bottle through a hole type screw cap and is sealed through a sealing ring.

Preferably, the upper end of the concentrated liquid containing pipe is in a pear-shaped design.

Preferably, the inner diameter of the concentrated liquid containing pipe is 10-20 mm, and the outer diameter of the concentrated liquid containing pipe is 20-30 mm.

Preferably, the inner diameter of the ampoule bottle is 8-12 mm, and the outer diameter of the ampoule bottle is 10-14 mm.

As another preferred scheme of the utility model, the ampoule internal diameter is 3 ~ 6mm, the ampoule external diameter is 4 ~ 8 mm.

Preferably, the ampoule bottle is provided with constant volume scales.

Preferably, the ampoule bottle is a flat-bottom bottle and is easy to store.

Preferably, the sealing ring is made of polytetrafluoroethylene.

As another preferred aspect of the present invention, the sealing ring is made of silica gel.

Preferably, the height of the concentrated liquid containing pipe entering the ampoule bottle is 1.5cm, the height is less than 1.5cm, tension is formed when the liquid falls, the liquid is difficult to flow downwards and affects the nitrogen blowing speed, and the height of the concentrated liquid containing pipe is more than 1.5cm and directly affects the nitrogen blowing speed.

(III) advantageous effects

The utility model has the advantages that:

1. the concentration liquid containing tube is separated from the tail tube, the tail tube is replaced by the ampoule bottle, multi-stage transfer is not needed during concentration, loss of substances to be detected is avoided, and meanwhile, the ampoule bottle is designed to be flat and is easy to store.

2. The concentrated liquid containing pipe and the ampoule bottle are sealed through a silica gel sealing ring, and the silica gel has a good sealing effect with low cost.

3. The ampoule bottle is from taking the constant volume scale, and solution directly is installed on the computer after the concentrated constant volume, and the ampoule bottle disposable avoids cross contamination, solves the difficult problem that the concentrated tub tail pipe of integral type is difficult to wash simultaneously.

Drawings

FIG. 1 is a schematic structural diagram of the present invention

In the figure: 1. a concentrated liquid containing pipe; 2. an ampoule bottle; 3. a hole-type nut; 4. and (5) sealing rings.

Detailed Description

As shown in figure 1, the utility model relates to a split type concentration tube, the concentration tube includes concentrated dress liquid pipe 1 and ampoule 2, concentrated dress liquid pipe upper end adopts the pyriform design, the lower extreme inserts ampoule part is 1.5cm, the pyriform radian inclines more the solution mobility is better, be favorable to the backward flow and wash of liquid, ampoule 2 is from taking the constant volume scale, can make things convenient for operator's accurate constant volume and to the control of concentrate, ampoule 2 is designed flat, can conveniently store, concentrated dress liquid pipe 1 is connected through cellular type nut 3 with ampoule 2, seal through sealing washer 4 simultaneously, sealing washer 4 takes the silica gel sealing washer, the silica gel material is sealed effectual and with low costs, the height that concentrated dress liquid pipe 1 got into ampoule 2 is 1.5cm, highly is less than 1.5cm, can form tension when the liquid whereabouts, liquid just is difficult, can influence the speed that nitrogen blows, the height of more than 1.5cm directly affects the nitrogen blowing speed.

After the sample adopts the split-type concentration tube of the utility model for concentration, because the utility model adopts the split design, the concentrated liquid filling tube 1 is separated from the tail tube, the ampoule bottle 2 is adopted to replace the tail tube, in order to solve the sealing problem, the concentrated liquid filling tube 1 is connected with the ampoule bottle 2 through the hole type screw cap 3, and is sealed by the silica gel sealing ring 4, the silica gel material has good sealing effect and low cost, the concentrated liquid is kept in the ampoule bottle 2, the concentrated liquid in the ampoule bottle 2 can be directly subjected to constant volume, the solution is directly operated on the machine after the concentrated constant volume, the ampoule bottle 2 can be used once, and does not need to be like the prior art, the concentrated liquid needs to be transferred out of the concentration tube or other containers, after the concentrated tube wall or other container walls are leached by fresh organic solvent for many times, the difficult problem of integral-type concentration tube tail tube cleaning is solved, all solutions are combined to be concentrated and, thus, the loss of the sample in the transfer process is avoided, the consumption of the organic solvent is reduced, the subsequent concentration time is reduced, the risk of cross infection between containers is reduced, the operation steps are reduced, and the contact chance between an operator and the organic solvent is reduced.

Any required specification can be made into according to the in-service use demand to this embodiment, and wherein ampoule 2 can design into the internal diameter and be 8 ~ 12mm, and the external diameter is 10 ~ 14mm, preferred internal diameter 3 ~ 6mm, external diameter 4 ~ 8mm, more preferred internal diameter is 6mm, external diameter 8 mm.

The concentration tube can be designed into any required size, or can be designed into different specifications according to matched instruments, no matter whether the concentration tube is a small-size concentration tube, a medium-size concentration tube or a large-size concentration tube, samples do not need to be transferred, the concentration tube 1 is used for concentration, and the ampoule bottle 2 is used for reserving and fixing the volume.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
