Description
Technical field
The utility model belongs to laboratory paraphernalia, is related to a kind of auxiliary liquid adding device.
Background technology
In routine experimentation, the situation for needing that certain quantity of fluid is quantitatively adding in the specimen cup of very little can be usually encountered.
In general, the instruments such as pipette, suction pipe, liquid-transfering gun, syringe can be used, suitable for the liquid that mobility is strong, viscosity is low.
However, once fluid sample viscosity is higher, just occurs to be difficult to draw or drip and be sprinkling upon specimen cup graduation mark above area
The situation in domain, causes liquid feeding certain difficulty, and measurement result can be even influenced when serious.In particular for ASTM D7094 and
For D6450 tests, the higher sample of the viscosity such as varnish, glue, high polymer can be usually run into.The instruments such as pipette, suction pipe are difficult
With pipette samples, can usually pollute graduation mark area above when toward liquid feeding in specimen cup, in addition drop be sprinkling upon specimen cup cup edge or
Among saucer, it is difficult to which wiped clean, serious influence is caused on experiment.
Therefore, it is necessary to invent a kind of auxiliary liquid adding device easy to high viscosity liquid.
The content of the invention
The utility model is beneficial in that, a kind of auxiliary liquid adding device can be provided, easy to high viscosity liquid sample
The liquid feeding into specimen cup, avoids polluting non-test region.
To realize above-mentioned function, a kind of auxiliary liquid adding device that the utility model is related to is characterized in that, including liquid feeding leakage
Bucket 1 and 2 two parts of stationary housings.
Addition funnel 1 is divided into filling opening 3, stagnant liquid passage 4 and liquid outlet 5 from top to bottom.
To be inverted shaped hollow round table, top edge extension, lower edge is connected filling opening 3 with stagnant liquid passage 4.Facilitate fluid sample
Topple over.
Stagnant liquid passage 4 runs through hollow cone, from top to bottom, channel diameter contracts last to be inverted.Fluid sample edge
Passage downlink simultaneously converges, and the active force between fluid sample and conduit wall causes reduced velocity flow.
Liquid outlet 5 runs through hollow cone for what is just put, and top is connected with the bottom that stagnant liquid passage 4 is shunk, and lower edge is
Extension circular arc.The fluid sample slowly flowed out from stagnant liquid passage 4, drips or is flowed slowly into along liquid outlet wall in specimen cup 7, and not
Graduation mark area above can be polluted.
Stationary housings 2 are shaped hollow round table, and upper end is fixed with stagnant 4 top edge of liquid passage, and frustum cone height is more than stagnant liquid passage 4
The sum of with the height of liquid outlet 5, ensure that device just may be used after 5 lower edge extension circular arc of liquid outlet and 7 graduation mark of specimen cup are fixed
Smoothly to buckle on platform.Can again liquid feeding when, whole device is fixed on platform, while caused by avoiding maloperation
The pollution in non-test region.
Beneficial effect：A kind of auxiliary liquid adding device is the utility model is related to, the filling opening of edge epi facilitates liquid pouring,
It will not cause to drop.Meanwhile the stagnant liquid passage of vertebral body can delays liquid flow velocity, it is slowly flowed out from liquid outlet, convenient control
Liquid volume added processed.Liquid outlet bottom is extension circular arc, is fixed at specimen cup graduation mark, coordinates stationary housings, it is ensured that non-test
Region exempts from pollution.It is beneficial to high viscosity liquid sample liquid feeding into specimen cup, and avoids polluting.

Embodiment
Embodiment one
By taking ASTM D7094 as an example, as shown in figure 3, auxiliary liquid adding device 6 is buckled on specimen cup 7,5 bottom of liquid outlet
Portion's extension circular arc is fixed at 7 graduation mark of specimen cup, is fixed on by stationary housings 2 on platform.By homogeneous sample, from filling opening
3 topple over a certain amount of sample, and liquid slow transits through stagnant liquid passage 4 and flows into specimen cup 7.When sample size is close to graduation mark, soon
Speed removes auxiliary liquid adding device 6.After use, auxiliary liquid adding device 6 is rinsed well with organic solvent and water and treats that next time is spare,
Or direct discard processing.
Above-described embodiment is only for illustration of the utility model, and is not the limitation to the utility model patent；Should
, it is noted that for those of ordinary skill in the art, in the case where not departing from the utility model concept, can also make
Go out various change and modification, these belong to the scope of protection of the utility model；Therefore, it is all with the utility model claims model
Done equivalent changes and modifications are enclosed, the coverage of the utility model claims should all be belonged to.
Claims (1)
1. a kind of auxiliary liquid adding device, it is characterised in that including addition funnel and stationary housings two parts；Addition funnel from upper and
Under be divided into filling opening, stagnant liquid passage and liquid outlet；Filling opening is inversion shaped hollow round table, top edge extension, lower edge and stagnant liquid
Passage is connected；Stagnant liquid passage runs through hollow cone, from top to bottom, channel diameter contracts last to be inverted；Liquid outlet is just
