Being further defined to of technical solutions of the utility model, described in clear up the material of bottle and described bottle cap be politef.
Further, the aspect ratio clearing up bottle and described bottle cap described in is (10:1) ~ (8:1).
Further, the radius of described sealing strip brush is equal with the radius of described through hole, is sealed by described through hole.
Further, described frame of clearing up includes upper plate, middle base plate and lower shoe, distance between described upper plate and said midsole plate is more than the distance between said midsole plate and lower shoe, and, be respectively provided with the fixing hole that position is mutually corresponding on described upper plate, middle base plate and lower shoe, the diameter of described fixing hole be more than described in clear up the diameter 1 ~ 2cm of bottle of bottle.
Further, clear up the upper plate of frame, middle base plate and lower shoe described in and be polypropylene material.
Beneficial effect: a kind of digestion instrument measured for fresh water water quality nitrogen content that this utility model provides, digestion process more seals, and more fully, digestion time is shorter, clear up inside and outside bottle will not cross-contamination, noiseless, result is more accurate；This utility model avoids occurs in digestion process that the color comparison tube mouth of pipe or pipe close rupture, the problem analyzed of resampling；Meanwhile, the through hole that this utility model is arranged, it is simple to use liquid-transfering gun in process of the test, convenient and swift, simple to operate, improve accuracy.
Accompanying drawing explanation
The structural representation clearing up bottle that Fig. 1 provides for this utility model；
The structural representation clearing up frame that Fig. 2 provides for this utility model.
Detailed description of the invention
Below technical solutions of the utility model are combined accompanying drawing to be described in detail, but protection domain of the present utility model is not limited to described embodiment.
Embodiment 1:The present embodiment provide a kind of for fresh water water quality nitrogen content measure digestion instrument, including clear up frame and with described clear up frame supporting clear up bottle.
Clearing up the structural representation of bottle as it is shown in figure 1, include that bottle 1 and bottle cap 2, bottle 1 and bottle cap 2 are spun by screw thread, the material clearing up bottle 1 and bottle cap 2 is politef.One through hole 4 and a cock cap 3 being connected with through hole 4 interference fit are set on bottle cap 2, and, the circumferentially arranged sealing strip brush in bottom of through hole 4, the radius of sealing strip brush is equal with the radius of described through hole 4, is sealed by through hole 4.And, the aspect ratio clearing up bottle 1 and described bottle cap 2 is (10:1) ~ (8:1).In the present embodiment, the height clearing up bottle 1 is 80mm, external diameter is 50mm, internal diameter is 42mm, the height of bottle cap 2 is 10mm, a diameter of 57+0.5mm of bottle cap 2, clears up the bottle mouth position above bottle 1 and is provided with screw thread, being provided with the screw thread matched with bottleneck inside bottle cap 2, bottle cap 2 can be tightened on bottle 1 by screw thread.Bottle cap 2 marks bottle number with blue label with clearing up accordingly on bottle 1, is numbered A1, A2.....An, and n is to need to use the quantity clearing up bottle.
Clearing up the structural representation of frame as in figure 2 it is shown, include upper plate 5, middle base plate 6 and lower shoe 7, its material is polypropylene material.Distance between described upper plate 5 and said midsole plate 6 is more than the distance between said midsole plate 6 and lower shoe 7, and, be respectively provided with the fixing hole 8 that position is mutually corresponding on described upper plate 5, middle base plate 6 and lower shoe 7, the diameter of described fixing hole 8 be more than described in clear up the diameter 1 ~ 2cm of bottle 1 of bottle.In the present embodiment, height between upper plate 5 and middle base plate 6 is 3cm, height between middle base plate 6 and lower shoe 7 is 2.5cm, the fixing hole 8 of multiple a diameter of 5.77cm is further respectively had on described upper plate 5, middle base plate 6 and lower shoe 7, between hole, spacing is 0.7cm, fixing hole 8 on described upper plate 5 and the fixing hole 8 on middle base plate 6 are corresponding, and the fixing hole 8 on middle base plate 6 and the fixing hole 8 on lower shoe 7 are corresponding..
