Abstract
The invention discloses an aseptic multi-point sampling apparatus, belonging to the technical field of sampling. The aseptic multi-point sampling apparatus comprises at least two mutually communicated acquisition ports; the acquisition ports are in externally threaded connection with bottle caps; the interior of the sampling tube is provided with detachable trays which are provided with through holes, and absorbent cotton are placed between the trays and the bottle caps; sampling tube is also internally provided with a pair of detachable tweezers; and at least one sampling tube is in externally threaded connection with a medium pipe. The aseptic multi-point sampling apparatus provided by the invention overcomes the disadvantage that a traditional sampling apparatus cannot sample samples in a plurality of states in a same environment, and realizes multi-point sampling of solid, liquid, dust or gas samples in a same environment; moreover, samples sampled at multiple points are separately stored, which is beneficial for subsequent arrangement and analysis of the samples.
Description
Technical field
The invention belongs to Sampling techniques field, be specifically related to a kind of aseptic multi-point sampling device.
Background technology
At present, in the departments such as oil, chemical industry, environmental protection, scientific research institutions, commonly used harvester gathers sample.By the difference (such as: solid, liquid or gas, particle diameter size etc.) of collected sample, need to select different harvesters, cause harvester effect more single, it is impossible to realize general.Such as: dust can only be sampled by dust sampling device, river low mud sampler can only be sampled by mud low to river, and liquid can only be sampled by liquid sampler, and air can only be acquired by air acquisition device.
Patent CN200820158068.2 discloses a kind of Novel liquid sampler, including support frame and sampling tube thereon, described sampling tube includes sample long tube and sampling bend pipe, has been sequentially communicated sampling long tube, spherical valve, hand pump, spherical valve and sampling bend pipe on skeleton.There is air in pipe when this Liquid sampler can solve sampling to cause sampling, there is the blocking pipe problems that deposit causes in container bottom.But this device can only realize sampling liquid, and liquid a point can only be sampled, it is impossible to realize multi-point sampling.
The patent No.: 201010194683.0 disclose a kind of dust sampling device, including dust taking tube, are charging aperture in the bottom of dust taking tube, are provided with at least one dust board of flexible connection at charging aperture；It is provided with overflow mechanism on dust taking tube top.The dust of different depth can be sampled by this device, and easy to operate.But its dust collected mixes be stored in dust taking tube completely, it is impossible to the sample realizing same environment multipoint acquisition separately stores, and the data that post analysis obtains do not possess representativeness.
The most generally there is a kind of multiple spot thief sampler, as it is shown in figure 5, symbol description in figure: 8, collecting tank；9, column spinner.In sampling process, being first inserted in sample by sampler, after arriving the degree of depth required, rotating sampler is to open collecting tank, and sample will drop in collecting tank, and rotating sampler, to cut out collecting tank, takes out sampler.This device can realize multidraw, and the sample of multidraw is separate, it is adaptable to powder, granule or the sampling of micro-adhesion article.But the sampling of this device can only be for the diverse location of same sample, it is impossible to realize, in same environment, the sample under various states is carried out multi-point sampling.
Summary of the invention
In order to overcome existing sampling apparatus can not realize the deficiency that the sample of various states is sampled by same environment, the present invention provides a kind of aseptic multi-point sampling device, this device is by arranging multiple acquisition port, and dismountable tweezers are set inside device, realize the sample of solid, liquid, dust or gaseous state is carried out under same environment multi-point sampling, and the sample of multi-point sampling separately stores, follow-up sample is carried out finishing analysis.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of aseptic multi-point sampling device, including sampling tube, sampling tube includes the acquisition port of at least two intercommunication, and acquisition port external screw thread connects bottle cap.Being positioned over inside acquisition port by the sample of collection, sample is isolated from the outside by bottle cap, it is to avoid introduced contaminants is mixed in sample, contaminated samples.
Preferably, described sampling tube is cross four-way pipe, has the acquisition port of four intercommunications, it is achieved carry out sampling and individually storing for four points of same environment.
Preferably, described sampling tube is internally installed dismountable pallet, and pallet is provided with through hole, is placed with absorbent cotton between pallet and bottle cap.Dust in gas, solid and liquid etc. can be sampled by absorbent cotton；Absorbent cotton is positioned on pallet, and in acquisition port, threaded bottle cap, is isolated from the outside sample, it is to avoid introduced contaminants is mixed in sample, contaminated samples.When all of sample is mixed by needs, it is only necessary to people's effort mixes through the through hole on pallet in sampling tube, the sample collected.
Preferably, at least one sampling tube is internally installed dismountable tweezers, and tweezers can realize sampling solid, has only to take out tweezers, clamp solid with tweezers and be positioned in sampling tube during sampling.Tweezers are positioned over inside sampling tube, it is to avoid introduced contaminants pollutes tweezers, has only to directly take out tweezers during use, convenient and swift.
Preferably, at least one sampling tube external screw thread connects cultivates base tube, cultivate substrate tube and be placed with culture medium, after collecting sample, active force carrys out returning on sampling tube and turns sampling tube, the culture medium cultivated in base tube enters on the sample within each culture tube, and sample finally returns back to cultivate substrate tube and cultivates in being dissolved in culture medium.
The invention have the advantage that by arranging multiple acquisition port, acquisition port external screw thread connects bottle cap, and it is internally provided with dismountable tweezers at device, realize the sample of solid, liquid, dust or gaseous state is carried out under same environment multi-point sampling, and the sample of multi-point sampling separately stores, follow-up sample is carried out finishing analysis.When needing to carry out mixing and cultivating by the sample of collection, it is only necessary to connected by external screw thread and cultivate base tube, it is sufficiently mixed culture medium therein and sample to finally return back to cultivate in base tube by the cultivation base tube that fluctuates and cultivates.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated:
In order to realize carrying out sampling and individually storing for four points of same environment, sampling tube 1 is cross four-way pipe, has the acquisition port 2 of four intercommunications, and acquisition port 2 external screw thread connects bottle cap 3.
Sampling sample for convenience and be individually stored in sampling tube 1 inside, described sampling tube 1 is internally installed dismountable pallet 4, pallet 4 is provided with through hole, is placed with absorbent cotton 5 between pallet 4 and bottle cap 3.
In order to the solid particle realized to external world is sampled, avoiding the device of introduced contaminants contamination sampling, sampling tube 1 is internally installed dismountable tweezers 6 simultaneously.
In order to carry out mixing and cultivating by the sample of collection, sampling tube 1 external screw thread connects cultivates base tube 7.
It is last that it is noted that obviously above-described embodiment is only for clearly demonstrating example of the present invention, and not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus amplified out or variation still in protection scope of the present invention among.
