Description
Technical field
The utility model is related to the glass apparatus preparation field of sensitive compound correlation special requirement, particularly to oxygen,
Sensitive liquid involved in water vapor sensitive liquid or reaction process accurately adds a kind of new accurate dress shifted and measure used
Put.
Background technology
High reaction activity is generally configured with to the compound of oxygen, water vapor sensitive and possesses special performance, with chemical work
The rapid development of industry, the use on chemical industry is more and more extensive, is extensively closed in pharmacy, national defence and field of scientific study
Note.For the transfer and measurement of this kind of oxygen, the liquid of water vapor sensitive, general organic chemistry procedures are clearly what is do not applied to,
Some special instruments and a set of cleverly operating technology must be used.At present, method the safest is full of indifferent gas
Carried out in the use for laboratory vacuum glove box of atmosphere, but since use for laboratory vacuum glove box is expensive, takes up a large area and day
The features such as often maintenance cost is higher, is restricted its popularity used, in the case of not satisfying the requirements in many laboratories,
It is exactly using Simple hand casing using a kind of possible alternative of relatively economical, but use cost is high, and operation is cumbersome, separately
It is outer, also without water, oxygen content detecting system, gas leakage easily to occur because removing water deaerating type of cycles without circulation, make oxygen in air,
Steam enters, once gas leakage, sensitive liquid is chemically reacted with oxygen, steam in air, and gently then sample goes bad, heavy then possible
Cause sensitive liquid spontaneous combustion or explosion, trigger security incident.In addition it is that common method is syringe transfer and amount to also have one kind
Take, but syringe needle exposure is in atmosphere, is very easy to trigger the reaction of sensitive liquid and oxygen, steam in air, draws
Send out security incident unnecessary.
Utility model content
The purpose of this utility model is that make up it is existing to oxygen, water vapor sensitive liquid shift and measure the prior art not
Foot part, there is provided a kind of new sensitive liquid transfer and dispensing device, not only manufacture craft is simple for the device, but also sensitive liquid
Convenient transfer, quick, positive effect, will not be by the oxygen in air during shifting and measuring sensitive liquid using the device
Gas and water vapour brings transfering system into, can effectively avoid security incident.
The utility model is achieved through the following technical solutions：
The utility model provides a kind of transfer of sensitive liquid and dispensing device, it include preceding air extraction connector, two mouth flask,
Double ground graduated cylinders, conduit and rear air extraction connector, the preceding air extraction connector are arranged on a mouth of two mouth flask, are evacuated after described
Connector is arranged on a mouth of double ground graduated cylinders, another mouth of the two mouth flask is equipped with thread rubber plug, double mills
Another mouth of mouth graduated cylinder is equipped with thread rubber plug, and the both ends of the conduit are arranged in two thread rubber plugs respectively.
Preferably, the both ends of the conduit are respectively provided with a double pointed syringe needle.
Compared with prior art, the utility model has following beneficial effect：
The distinguishing feature of the utility model is cheap and easy to get, safe, easy to use compared with traditional sensitive liquid transfer device,
Oxygen, steam in ingress of air are not required during transfer and measurement, whole transfer process is completed in seconds, due to making
It is tool scale ground graduated cylinder, whole transfer and measurement process accurately controls, and greatly facilitates the transfer of sensitive liquid
And measurement；
In addition, sensitive liquid transfer and dispensing device make full use of the gas pressure of additional inert gas, can basis
Difference transfer and measure object volumes number, by varying the internal diameter of double pointed syringe needle is lengthened, to control transfer and measure liquid
Speed, while whether according to lengthening double pointed syringe needle one end by controlling and entering liquid, to control the double pointed syringe needle of lengthening whether residual
Liquid stay, makes residual liquid enter two mouthfuls of round-bottomed flasks by the way of inert atmosphere is blown；
It is of low cost meanwhile sensitive liquid transfer and dispensing device also have reuse effect, are used multiple times.

Embodiment
The utility model is described in detail with reference to specific embodiment.Following embodiments will be helpful to this area
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that to ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made.
These belong to the scope of protection of the utility model.
As shown in Figure 1, a kind of sensitive liquid transfer provided by the utility model and dispensing device, it includes preceding air extraction connector
1st, two mouth flask 2, double ground graduated cylinders 3, rear air extraction connector 4 and conduit 5, preceding air extraction connector 1 are arranged at a mouth of two mouth flask 2
On, rear air extraction connector 4 is arranged on a mouth of double ground graduated cylinders 3, another mouth of two mouth flask 2 is equipped with thread rubber plug
6, a thread rubber plug 6 also is provided with another mouth of double ground graduated cylinders 3, and the both ends of conduit 5 are arranged in two screw thread glue respectively
In plug 6.
For the ease of the access of conduit, the both ends of conduit 5 are respectively provided with a double pointed syringe needle.
In use, by preceding air extraction connector 1, two mouth flask 2, double ground graduated cylinders 3, rear air extraction connector 4, conduit 5 and screw thread glue
Plug 6 is installed as shown in Figure 1, is sensitive liquid transfer and dispensing device.Have the preceding air extraction connector 1 and vacuum pump of glass section door
It is connected, the glass section door of preceding air extraction connector 1 is opening, and rear air extraction connector 4 is connected with inert gas source, rear air extraction connector 4
Glass section door be in off state, start vacuum pump, take out 30 seconds, the glass section door of air extraction connector 1, is evacuated after unlatching before closing
Connector 4 has glass section door, makes inert gas full of sensitive liquid transfer and dispensing device.Repeat this step three times, then it is described quick
Inert gas is full of in the transfer of sense liquid and dispensing device, forms sensitive liquid transfer and dispensing device under inert gas shielding.
When transfer and measurement sensitive liquid, preceding air extraction connector 1 connects bubbler, and rear air extraction connector 4 is connected with inert gas source,
The glass section door of air extraction connector 4 after unlatching, sensitive liquid by the pressure of inert gas, accurately shifted and measured to two mouthfuls
