Abstract
The utility model discloses a kind of reaction tube that accurately can control reagent dropwise speed, relate to chemical reaction apparatus field, mainly solve a test tube as reagent dropwise during reacting environment loaded down with trivial details and uppity problem.A kind of reaction tube that accurately can control reagent dropwise speed, comprise cylindrical tube and rotary opening and closing device, described rotary opening and closing device is arranged on the lower 1/3-1/2 place of cylindrical tube body bulk, and the described cylindrical tube tube wall be positioned at above rotary opening and closing device is provided with the volume mark scale upwards extended from rotary opening and closing device.The utility model by above-mentioned setting solve exist in traditional operation complex operation, measure reagent not accurately, the uppity problem of drop rate, need shortcomings such as mixing in advance when needing two kinds of reagent to drip simultaneously.
Description
Technical field
The utility model relates to chemical reaction apparatus field, refers to a kind of reaction tube that accurately can control reagent dropwise speed especially.
Background technology
As everyone knows, test tube as a kind of instrument of chemical experiment of routine, can be used for contain fluid and solid reagent, small quantity reaction generator, heat the collection of a small amount of liquid and solid reagent and a small amount of gas.Cuvette construction is simple and of many uses, is applied to chemical, environment evaluation and test and medical domain in large quantities.
Generator as small quantity reaction is one of main application of test tube, and traditional laboratory operation measures quantitative different reagent with dropper to be added drop-wise in test tube respectively and to react.Often there is complex operation in this operation, measure reagent not accurately, drop rate is wayward, need shortcomings such as mixing in advance when needing two kinds of reagent to drip simultaneously.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and the utility model provides a kind of reaction tube that accurately can control reagent dropwise speed.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of reaction tube that accurately can control reagent dropwise speed, it is characterized in that: the cock comprising cylindrical tube and arrange along body radial direction, the inwall at the axial lower 1/3-1/2 place of described body is provided with along the centrosymmetric annular boss in body axis, the longitudinal cross-section of described annular boss is trapezoidal, described annular boss symmetrical centre place forms a body axially extending bore, described body is provided with a lateral opening and runs through the cock cavity volume of body axially extending bore, described cock comprises cock body and handle, described cock body and knob are rigidly connected, described cock body forms rotatable sealing with cock cavity volume adaptation and coordinates, on described cock body, the position of corresponding body axially extending bore is provided with cock body through hole and meets cock body radius > body axially extending bore radius >=cock body through hole radius, the described body tube wall be positioned at above cock is provided with the volume mark scale upwards extended from cock.
By adopting such scheme, consequently: when ensureing that test tube is proper use of, intuitively and accurately can control the amount of reagent dropwise and speed and make operation simpler.If need plurality of reagents to drip simultaneously, another instrument is not needed to carry out premixed.
As further setting of the present utility model: described cock is arranged on cylindrical tube body bulk 1/2 place.
By adopting such scheme, consequently: when guaranteeing that test tube normally uses, process laboratory sample as much as possible.
As further setting of the present utility model: described cock adopts glass material, the contact surface of cock cock body and cock cavity volume is ground design.
By adopting such scheme, consequently: one deck vacuum ester can be smeared on cock ground face before operation, can ensure that the sealing effectiveness of test tube can improve again the smooth and easy degree of operation.
As further setting of the present utility model: described cock adopts polytetrafluoroethylene (PTFE) material, and the contact surface of cock cock body and cock cavity volume is smooth design.
By adopting such scheme, consequently: polytetrafluoroethylene (PTFE) belongs to high-performance corrosion-resistant material, most reagent can be suitable for.
As further setting of the present utility model: described cylindrical tube is provided with from bottom to the volume mark scale that cock terminates.
By adopting such scheme, consequently: can the volume of reagent after real-time monitored mixing, and control.
