Abstract
The utility model discloses a filter column for detecting aquatic products. The filter column comprises a plunger, a column barrel, a bottom filter film with protection, and an outlet drainage tube, wherein the plunger consists of a handle, a middle shaft and rubber, one end of the middle shaft is connected with the handle, and the other end of the middle shaft is connected with the rubber which is matched with the column barrel; the diameter of the column barrel is 0.6-1.5 cm, the effective capacity of the column barrel is 1.0-3.0 ml, the bottom of the column barrel is of the shape of a circular truncated cone, and the column barrel is communicated with the outlet drainage tube; the bottom filter film is arranged in the position near the bottom of the column barrel. According to the filter column for detecting the aquatic products, provided by the utility model, a simple filter device is provided for detecting samples of the aquatic products, the efficiency of detecting work is improved, and the stability of detecting results is further ensured.
Description
Technical field
The utility model relates to a kind of Filter column, and specifically a kind of aquatic products detect the Filter column of use.
Background technology
Along with the raising of people's living standard, the output of aquatic products production and consumption also improves greatly, and the quality problems of aquatic products make again the general common people worry, and how to check the quality good or not of aquatic products, are the problems that ordinary people pays special attention to.According to the requirement of relevant alimentary codex, Food Inspection regulation, the detection that aquatic products need to be by aspects such as organoleptic examination, physical examination, chemical analysiss is with the quality safety of assurance aquatic products.When aquatic products are carried out to medicament residue detection, pretreatment process final step all needs to extract, and after filtering, just can offer instrumental analysis, and the filtration consumptive material that laboratory is used is at present the combination of filter and syringe.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of aquatic products to detect the Filter column of use.
The technical scheme that the utility model technical solution problem is taked is:
The utility model comprises plunger, column casing, has bottom filter membrane and the outlet drainage tube of protection.
Described plunger is comprised of handle, axis and rubber, axis one end connecting handle, and the other end connects rubber, and described rubber matches with column casing; Described column casing diameter is 0.6～1.5 centimetre, and useful capacity is 1.0～3.0 milliliters, and its bottom is circular platform type, and with outlet drainage tube UNICOM, at column casing, near bottom position, be provided with described bottom filter membrane.
Described bottom filter membrane is divided into upper strata protection filter membrane, organic phase or water filter membrane and lower floor's protection filter membrane; It is just circular that described upper strata protection filter membrane and lower floor's protection filter membrane are grid, and upper strata protection filter membrane and lower floor's protection filter membrane are clipped in the middle organic phase or the water filter membrane of 0.22 micron or 0.45 micron.
The utility model provides a kind of aquatic products to detect the Filter column using, and during for aquatic products sample detection, provides simple filtration unit, has improved the efficiency of testing, has also guaranteed the stability of testing result.

Fig. 1 is the utility model structural representation.
Fig. 2 is column casing sectional view.
Embodiment
Below in conjunction with embodiment, the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of aquatic products described in the utility model detect the Filter column of use, mainly by plunger, column casing 5 be comprised of the bottom filter membrane 6 of protecting and outlet drainage tube 7.Plunger is comprised of handle 1, axis 2 and rubber 3, axis one end connecting handle, and the other end connects rubber, and described rubber matches with column casing; Described column casing diameter is 0.6～1.5 centimetre, and useful capacity is 1.0～3.0 milliliters, and its bottom is circular platform type, and with outlet drainage tube UNICOM, at column casing, near bottom position, be provided with described bottom filter membrane.Bottom filter membrane is divided into upper strata protection filter membrane 6-1, organic phase or the protection filter membrane 6-3 of water filter membrane 6-2He lower floor; It is just circular that described upper strata protection filter membrane and lower floor's protection filter membrane are grid, and upper strata protection filter membrane and lower floor's protection filter membrane are clipped in the middle organic phase or the water filter membrane of 0.22 micron or 0.45 micron.This Filter column is disposable experiment consumptive material, in aquatic products testing, with this Filter column, carrys out filtered sample extract, is finished rear direct abandonment.
According to the extract of required filtration, become the Filter column of component selections different size, Filter column is provided with organic phase or the water filter membrane of 0.22 micron or 0.45 micron.Directly fetch corresponding this Filter column, handle 1 is taken out plunger to be placed on experiment table, the sample extracting solution that needs are filtered is transferred in column casing 5, plunger is inserted into column casing 5 from post mouth 4, the variation of depresses plunger extruding column casing internal air volume, flows to the sample extracting solution in column casing the sample injection bottle of putting well from outlet drainage tube 7 by bottom filter membrane 6.Sample extracting solution passes through filter membrane again through bottom filter membrane protection upper strata, then through filter membrane protection lower floor, the ramped bottom surface center of the liquid of process filter membrane along ramped bottom surface 8 toward column casing 5 is pooled to 7 outflows of outlet drainage tube, flows in the sample injection bottle placing.
It should be noted that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model is not limited to the embodiment described in embodiment; every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, belong to protection domain of the present utility model equally.
