Description
Technical field
The utility model belongs to instrument and equipment technical field, and in particular to a kind of achievable sample extraction, filtering and transfer
Sample extraction bottle.
Background technique
Chemical analysis and test in, it is often necessary to substance carry out pre-treatment, such as extraction, filtering and collect and etc.,
Then sample required for obtaining just can be carried out analysis and test.Extraction the specific steps are weigh substance to ground triangular flask
In, extractant oscillation extraction is added, then again separates extract liquor.It, need to be by solid sample in the specific steps of filtering
The mixture of residue and extracting solution is poured into bottleneck and is placed in the funnel of qualitative filter paper folding, then by filtered extracting solution
Collection just can be carried out subsequent measurement in sample cell.It needs to shift sample several times in sample pretreatment process, it is not easy enough, it influences
The treatment effeciency of sample and the efficiency of detection work；And it may be because introducing impurity and extracting solution accidentally in transfer process
It splashes etc. and to influence the reliability of testing result.In order to avoid operating brought experimental error, preferably before sample
Transfer sample is not needed in treatment process can directly extract, filter and collect to obtain sample to be analysed, compel and need to design
It is a kind of for sample extraction, filtering and the integrated apparatus of transfer.
The utility model aims to solve the problem that the above problem.
Utility model content
The utility model designs a kind of for sample extraction, filtering and the integrated apparatus of transfer, is handled using the device
Sample have the advantages that processing it is simple, conveniently, effect of extracting it is good.
The utility model discloses the sample extraction bottle of a kind of achievable sample extraction, filtering and transfer, including with lower component：
Outer tube 1, sealed bottom；For placing sample.
Inner sleeve 2, outer diameter are adapted with the internal diameter of the outer tube 1；
Catheter 4 is located in the inner sleeve 2, and there are an extension mouth, the extension mouth wall and the inner sleeve 2 in lower end
Lower end inner wall be sealedly and fixedly connected；Catheter 4 is used for transfer liquid.
Sieve plate 3, in the lower ending opening of the inner sleeve 2；For filtered sample.
Preferably, the length of the inner sleeve 2 is greater than the length of the outer tube 1；The catheter 4 and the inner sleeve
2 upper ports are fixedly connected to form compression face 21；It exerts oneself downwards on compression face 21, inner sleeve 2 is pressed downward, and sample passes through sieve
Plate 3 is filtered, and can realize transfer.
Preferably, the sieve plate 3 is multiple.Filler, such as solid phase extraction filler can be placed between multiple sieve plates.
Preferably, the oral area of the outer tube 1 has a sealing ring 11, and the bottom of the outer tube 1 is flat.When being surpassed
When sound extracting operation and filtering transfer operation, the sealing ring 11 can seal the inner sleeve 2 of insertion, make liquid will not
Spluttering comes out.
Preferably, the top of the catheter 4 is stretched out outside the inner sleeve 2, and back bending is downward.The downward drain of back bending
Pipe 4 is transferred to sample bottle 610 and waste collection bottle 620 conducive to liquid.
The beneficial effects of the utility model：
Achievable sample extraction provided by the utility model, filtering and transfer sample extraction bottle, the pre-treatment of sample
Transfer sample is not needed in journey can directly extract, filter and collect to obtain sample to be analysed, effectively prevent operation institute's band
Come experimental error, have the advantages that processing simply, conveniently, effect it is good.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below with reference to attached drawing and reality
Example is applied, the utility model is described in further detail.
A kind of achievable sample extraction, filtering and the sample extraction bottle of transfer of the utility model, including with lower component：
Outer tube 1, sealed bottom；
Inner sleeve 2, outer diameter are adapted with the internal diameter of the outer tube 1；
Catheter 4 is located in the inner sleeve 2, and there are an extension mouth, the extension mouth wall and the inner sleeve 2 in lower end
Lower end inner wall be sealedly and fixedly connected；
Sieve plate 3, in the lower ending opening of the inner sleeve 2；
Preferably, the length of the inner sleeve 2 is greater than the length of the outer tube 1；The catheter 4 and the inner sleeve
2 upper ports are fixedly connected to form compression face 21；The compression face 21, which can apply pressure, is pressed down inner sleeve 2, and sample passes through
