Description
Technical field
The utility model relates to a kind of bottleneck adapter, specially a kind of quantitative liquid-distributor bottle for anaerobic liquid packing
Mouth adapter.
Background technique
On the one hand anaerobism solution needs accurate quantitative analysis in packing, on the other hand need to avoid being mixed into oxygen, it is therefore necessary to
It is dispensed in the environment of anaerobic using the device that can be quantified.Anaerobism solution is mainly driven away in liquid by way of heating
Oxygen, therefore usually conical flask etc. is heatable, prepares in non-screw socket container.The bottleneck type is adjustable, and dispenser is to pipette large-scale appearance
The device of liquid in device, have many advantages, such as good airproof performance, it is quantitative accurate, be easy to unpick and wash, obtained answering extensively in liquid subpackage
With.But this kind of dispenser is only applicable to standard screw socket, included adapter is suitble to common laboratory screw socket reagent bottle,
It is not used to the non-screw socket container such as conical flask.
In addition, needing to be passed through the inert gases such as nitrogen in the packing of anaerobism solution to guarantee that solution is in anaerobic ring always
In border.But it is molten cannot to provide inert gas shielding without reserved air-path interface for the adjustable dispenser of the bottleneck type and its adapter
Liquid is mixed into oxygen when also not can avoid packing.
For these reasons, the adjustable dispenser of existing the bottleneck type and its adapter are not used to quantitative point of anaerobism solution
Dress still lacks the adjustable quantitative subpackage apparatus for being directed to anaerobic liquid currently on the market.
Utility model content
In order to solve problem above, the purpose of the utility model is to provide a kind of quantitative liquid separatings for anaerobic liquid packing
Device bottleneck adapter is passed through inert gas in packing, to guarantee that solution is in oxygen-free environment always, is in addition also applied for boring
The non-screw socket container such as shape bottle.
In order to achieve the goal above, the technical solution adopted in the utility model: a kind of quantifying for anaerobic liquid packing
Dispenser bottleneck adapter, including crossover sub, plug and silicone tube；Crossover sub for connecting quantitative liquid-distributor, detest by separation
On the one hand oxygen liquid, plug are used to seal the bottleneck of separation container, be on the other hand used for fixed conversion connector, silicone tube is for soaking
Enter inside separation container, draws anaerobic liquid into quantitative liquid-distributor.
The crossover sub includes connector top, connector middle part and hollow tube, is provided with cavity in the connector top, institute
It states in the middle part of connector and is provided with through-hole, the through-hole connection cavity and hollow tube, the hollow tube connect silicone tube；When starting point
When dress, anaerobic liquid successively passes through silicone tube, hollow tube, through-hole and cavity, is finally drawn onto quantitative liquid-distributor.
The plug is provided centrally with adapter fixation hole, and multiple ventholes, the hollow tube insertion are provided on plug
In adapter fixation hole；At work, plug upper end is located in the middle and top part of connector, it is solid that hollow tube connects hose insertion adapter
Determine in hole and be immersed in liquid to be packed, for a venthole for connecting inert gas air supply pipe, inert gas enters packing
In container, the gases such as oxygen in separation container are then discharged from other ventholes, to achieve the purpose that substitution gas.
Further, the connector upper external is provided with screw thread, it is threadedly coupled quantitative liquid-distributor, it is simple and convenient and close
Envelope property is good.
Further, the stopper material is silica gel, silica gel is easy to get and cheap, may be produced that the plug of different model
Son is applicable in the bottleneck of different separation containers.
The utility model has the beneficial effects that the bottleneck adapter can provide inert gas, for replacing in separation container
Oxygen guarantees that solution is in anaerobic environment during packing；Meanwhile it can be by the plug of replacement different model, directly and respectively
The liquid container of seed type connects, and suitability is strong, applied widely.

Specific embodiment
It is practical new to this with reference to the accompanying drawing in order to keep the purpose of this utility model, technical solution and advantage clearer
Type is further elaborated.
Please refer to Fig. 1, a kind of quantitative liquid-distributor bottleneck adapter for anaerobic liquid packing, including crossover sub 1, plug
Son 2 and silicone tube 3.
As shown in Figures 2 and 3, the crossover sub 1 includes in the middle part of connector top 11, connector 12 and hollow tube 13, described to connect
It is provided with cavity 111 in head top 1, is provided with through-hole 121 in the connector middle part 12, the through-hole 121 is connected to 111 He of cavity
Hollow tube 13, the hollow tube 13 connect silicone tube 3.
As shown in figure 4, the plug 2 is provided centrally with adapter fixation hole 21, multiple ventholes are provided on plug 2
22, the hollow tube 13 is inserted into adapter fixation hole 21.
