Abstract
The utility model belongs to the improvement of aflatoxin microtrabeculae screening detection device structure, especially an aflatoxin microtrabeculae screening detection device, the appearance liquid funnel rigid coupling of circle conical hopper form is setting up the scale on the tubular column shaft on the axle center is provided with the opening on the tubular column upper portion of through -hole, at tubular column bottom rigid coupling to have the internal screw thread base, is setting up the gas pocket on the base, has the internal screw thread base and closes with the outer thread to match of the bottleneck of waste liquid bottle. The utility model discloses it is rational in infrastructure, the operation of being convenient for, the in -process of can avoiding packing is measured repeatedly, and can avoid packing or appearance liquid is unrestrained and the waste and the pollution that cause reduce the injury to personnel.
Description
Technical field
This utility model belongs to the improvement of aflatoxin microtrabeculae selective mechanisms apparatus structure, particularly a kind of aflatoxin microtrabeculae selective mechanisms device.
Background technology
Aflatoxin is the derivant of dihydrofuran cumarin, i.e. contains a bifuran and a cumarin (coumarin).In known mycotoxin, aflatoxin has extremely strong carcinogenic, teratogenesis, mutagenesis, its toxicity is 10 times of potassium cyanide, 68 times of arsenicum, also it is most stable of one in all mycotoxins, and distribution is very wide, worldwide most raw-food materials and manufactured goods all there is harm in various degree.At present at laboratorys such as food test, scientific research colleges and universities, commercial production, in use GB GB/T5009.23-2003 the second method batch screening sample during aflatoxin, use from filling microtrabeculae, there is some deficiency following: (1) microtrabeculae pipe need to be placed on pipe support, it is impossible to stands on experiment table top；(2), during certainly filling out microtrabeculae, instrument to be used repeatedly measures the height of various filler, complex operation；(3), during filler or extraction sample liquid being placed in microtrabeculae, easily trickle down, cause waste and pollute table top；(4), during sample measuring liquid and developing solvent are treated in addition, experimenter is easily damaged by organic volatile.
Utility model content
The purpose of this utility model is to provide a kind of aflatoxin microtrabeculae selective mechanisms device, and it is rational in infrastructure, it is simple to operation, repeatedly measures during can avoiding filler, can avoid filler or sample liquid is unrestrained and the waste that causes and pollution, reduce the injury to personnel.
The purpose of this utility model is achieved in that a kind of aflatoxin microtrabeculae selective mechanisms device, the sample liquid funnel of conical funnel shape is fixed in axle center and is provided with on the opening on tubing string top of through hole, tubing string shaft arranges scale, affixed in tubing string bottom have female base, pore is set on base, has female base and match with the external thread of bottleneck of waste liquid bottle.
This utility model uses female thread base to stand on table top, it is simple to operation；Multiple graduation marks empirically require directly to be engraved on microtrabeculae shaft, it is to avoid repeatedly measure during filler；Filler or sample liquid enter buccal funnel and are integrated with microtrabeculae shaft, and in horn-like, it is to avoid filler or sample liquid is unrestrained and the waste that causes and pollution；Microtrabeculae base female thread matches with waste liquid bottle external screw thread and waste liquid is sealed in waste liquid bottle, reduces the injury to personnel；Pore is had, it is ensured that liquid relies on gravity to flow in waste liquid bottle on base；This new patent simple in construction, processing ease, with low cost.
This utility model operating procedure:
Bottom blocks with a small amount of absorbent cotton, inserts and strike tightly by filler the most successively by microtrabeculae shaft high scale, keeps microtrabeculae vertical, make interface between two kinds of fillers concordant, finally blocked with a small amount of absorbent cotton at filler top during filler.Carry out after extraction completes, sample liquid to be extracted and adding microtrabeculae by sample liquid funnel by GB/T5009.23-2003 the second method by testing sample, when sample liquid stream to top layer, add developing solvent, to be deployed dose flowed after can under wavelength is 365nm ultraviolet light observed result.
This utility model is rational in infrastructure, it is simple to operation, it is to avoid repeatedly measure during filler, it is to avoid filler or sample liquid is unrestrained and the waste that causes and pollution, reduces the injury to personnel.
Accompanying drawing explanation
Being further described this utility model below in conjunction with accompanying drawing, Fig. 1 is this utility model main TV structure schematic diagram, and Fig. 2 is the main TV structure schematic diagram that sample liquid funnel coordinates base, and Fig. 3 is the main TV structure schematic diagram of waste liquid bottle.
Detailed description of the invention
A kind of aflatoxin microtrabeculae selective mechanisms device, as shown in Figure 1, Figure 2, Figure 3 shows, the sample liquid funnel 1 of conical funnel shape is fixed in axle center and is provided with on the opening on tubing string 2 top of through hole, tubing string 2 shaft arranges scale 5, affixed in tubing string 2 bottom have female base 6, pore 3 is set on base 6, has female base 6 and match with the external screw thread of waste liquid bottle 4 bottleneck.
