Abstract
The utility model discloses a device for measuring effective nitrogen in soil in a laboratory, which comprises a spread utensil (1). The spread utensil (1) is formed by an inner chamber and an outer chamber, and a sealing cover is respectively arranged on the inner chamber and the outer chamber of the spread utensil (1). Therefore, when the spread utensil is moved, liquid in the outer chamber of the spread utensil cannot be swayed to the inner chamber of the spread utensil, movement speed of the spread utensil can be substantially improved, and operating speed can be improved. Each sealing cover is formed by an outer chamber end cover and an inner chamber end cover which adopt a draw bar to connect, so that users can push the outer chamber end cover to pull the draw bar to take off the inner chamber end cover, and vibration during cover taking-off can be avoided. The outer chamber end cover is made of transparent materials, so that the users can conveniently observe and locate by eyes.
Description
Technical field
The utility model relates to the device that a kind of laboratory is used for measuring available nitrogen in the soil, belongs to teaching, scientific experiment chamber apparatus.
Background technology
Available nitrogen in the measured soil is an important evidence of understanding effective ingredient in the soil; Existing method of testing the most efficiently is a diffusion method; Its main testing appliance is a diffusion boat, and it is that mistress at diffusion boat puts into tested soil and a certain amount of aqueous slkali during test, pours a certain amount of indicator solution at the diffusion boat inner room; After sealing; The diffusion boat of interior Sheng soil and reagent is sent into baking oven, and indoor solution can not shake out the entering inner room outside in moving process, requiring, otherwise can cause indicator to lose efficacy.But because of diffusion boat is that interior mistress's upper space is intercommunication, and chamber is lower, in moving process, just needs extreme care like this, and the failure of an experiment rate is higher, has a strong impact on operating speed.
Summary of the invention
The technical matters that the utility model will solve provides and a kind ofly can prevent that liquid spills in the diffusion boat inner room, and the laboratory that is convenient for measuring, can improves test speed is used for measuring the device of available nitrogen in the soil, can overcome the deficiency of prior art.
The technical scheme of the utility model is: it comprises diffusion boat, and diffusion boat is made up of inner room and mistress, on the inner room of diffusion boat and mistress, is respectively equipped with gland bonnet.
Gland bonnet is constituted by mistress's end cap and inner room end cap, and mistress's end cap is connected to diffusion boat mistress edge, and the inner room end cap is movably connected on mistress's end cap through pull bar.
Mistress's end cap is processed by transparent material.
Pull bar is positioned at the center of mistress's end cap.
Compare with prior art; The utility model is through being provided with gland bonnet respectively on the inner room of diffusion boat and mistress; When moving diffusion boat, just the liquid among the diffusion boat mistress is shaken into inner room like this, can increase substantially the translational speed of diffusion boat, improve operating speed.Gland bonnet is constituted by mistress's end cap and inner room end cap, adopts pull bar to connect between the two, just can the inner room end cap be taken off according to mistress's end cap pulling pull bar like this, can avoid getting the vibrations when covering.Mistress's end cap is processed by transparent material, can conveniently observe the location with eyes like this.The utility model also has advantage simple in structure and easy to use simultaneously.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
Embodiment 1: as shown in Figure 1, diffusion boat 1 is made up of inner room and mistress, and liquid shakes out among the mistress when preventing to move, and on the inner room of diffusion boat 1 and mistress, is respectively equipped with gland bonnet 2.The concrete structure of gland bonnet 2 is constituted by mistress's end cap 3 and inner room end cap 4; Mistress's end cap 3 is the lid that an area is slightly larger than the diffusion boat sectional area, and for making things convenient for inner room end cap 4 location, it adopts the mode of transition fit to be connected to the mistress edge of diffusion boat 1; Observe for convenient; Mistress's end cap 3 is preferably processed by transparent material, and a pull bar 5 is set in the center of mistress's end cap 3, and inner room end cap 4 is movably connected on mistress's end cap 3 through pull bar 5.
Claims (4)
1. a laboratory is used for measuring the device of available nitrogen in the soil, and it comprises diffusion boat (1), and diffusion boat (1) is made up of inner room and mistress, it is characterized in that: on the inner room of diffusion boat (1) and mistress, be respectively equipped with gland bonnet (2).
2. laboratory according to claim 1 is used for measuring the device of available nitrogen in the soil; It is characterized in that: gland bonnet (2) is constituted by mistress's end cap (3) and inner room end cap (4); Mistress's end cap (3) is connected to diffusion boat (1) mistress edge, and inner room end cap (4) is movably connected on mistress's end cap (3) through pull bar (5).
3. laboratory according to claim 2 is used for measuring the device of available nitrogen in the soil, it is characterized in that: mistress's end cap (3) is processed by transparent material.
