Abstract
The utility model relates to a titration device, and particularly relates to a simple titration device. The simple titration device provided by the utility model comprises an adjustable pipettor and a microscale test solution bottle with scales, wherein the adjustable pipettor comprises a negative pressure vacuum sucker, the upper part of the negative pressure vacuum sucker is provided with a button, the lower part of the negative pressure vacuum sucker is provided with a suction nozzle, and the negative pressure vacuum sucker is externally provided with a sleeve. The simple titration device provided by the utility model has the advantages that the operation is simple, the use is convenient, the carry is easy, a detection result is exact and timely, the cost is low, and a condition that the enterprise production is smoothly preformed is guaranteed.
Description
Technical field
The utility model relates to a kind of titration apparatus, is specifically related to a kind of simple and easy titration apparatus.
Background technology
Titration apparatus commonly used generally comprises buret and triangular flask, and these glass apparatus are essential in experiment, brought great directive function to production.At work, when particularly working at the scene, often to use titration apparatus, but titration apparatus volume of the prior art is large, carry inconvenience, can not directly bring it into working site, but sample is fetched, after the laboratory goes out result, feed back to again the scene, cause result to lag behind, thereby affected normally carrying out of producing.Namely allow to bring titration apparatus into working site, also because it uses inconvenience, affected the progress of work.
The utility model content
According to above deficiency of the prior art, technical problem to be solved in the utility model is: a kind of operation and easy to use is provided, carries easily, guaranteed to produce the simple and easy titration apparatus that carries out smoothly.
The technical scheme that its technical matters that solves the utility model adopts is:
Simple and easy titration apparatus described in the utility model comprises that an adjustable pipette and one arrange graduated micro-test solution bottles.
Described adjustable pipette comprises the negative-pressure vacuum suction pipe, and negative-pressure vacuum suction pipe top arranges button, bottom suit suction nozzle, outer setting sleeve pipe.
It is accurate that the negative-pressure vacuum suction pipe moves liquid, and precision is high, and bottom suit suction nozzle makes directly contact measured test solution of adjustable pipette, has extended the tenure of use of adjustable pipette.The quantity of suction nozzle can be for a plurality of, in order to using.
The capacity of described micro-test solution bottles is 1.0-2.0ml, and the top can arrange bottle cap, and after bottle cap was set, when firmly rocking, the solution of micro-test solution bottles was difficult for being rocked out, affects result.Trace test solution bottles shape is preferably cylindrical.
During work, standard solution is put into micro-test solution bottles, then add indicator to shake up, again suction nozzle is arranged on bottom the negative-pressure vacuum suction pipe, after extracting test solution to be measured, joins in micro-test solution bottles, shake up, whether the color of seeing indicator changes, if do not change, then gets test solution to be measured and continues to add.Due to the concentration that has calculated in advance standard solution and consumption, indicator this phenomenon of suddenling change can not appear in the test solution trace very that sucks of adjustable pipette in addition after therefore slowly adding, obtained result preferably, and what guaranteed to produce carries out smoothly.
The beneficial effect that the utility model has is:
The utility model is simple to operate, easy to use, carry easily, testing result accurately, in time, and cost is lower, what guaranteed that enterprise produces carries out smoothly.
Description of drawings
Fig. 1 is the utility model structural representation;
In figure: 1, suction nozzle; 2, sleeve pipe; 3, button; 4, adjustable pipette; 5, negative-pressure vacuum suction pipe; 6, bottle cap; 7, micro-test solution bottles.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, described simple and easy titration apparatus comprises that an adjustable pipette 4 and one arrange graduated micro-test solution bottles 7.Transfer pipettor 4 to comprise negative-pressure vacuum suction pipe 5, negative-pressure vacuum suction pipe 5 tops arrange button 3, bottom suit suction nozzle 1, outer setting sleeve pipe 2.The capacity of trace test solution bottles 7 is 1.0-2.0ml, and the top arranges bottle cap 6, and micro-test solution bottles 7 is cylindrical.
During work, standard solution is put into micro-test solution bottles 7, add indicator to shake up, standing.Suction nozzle 1 is arranged on negative-pressure vacuum suction pipe 5 bottoms again, slowly joins in micro-test solution bottles 7 after drawing test solution to be measured, the limit edged shakes up, and sees whether the color of indicator changes, if do not change, continues to add test solution to be measured, until till indicator discoloration.The utility model is simple to operate, easy to use, carry easily, testing result accurately, in time, and cost is lower, what guaranteed that enterprise produces carries out smoothly.The principle of work of adjustable pipette 4 is identical with suction type adjustable pipette principle of work of the prior art.
Application Example:
Employing good fortune generation Tyke clean-out system cleaning equipment, and use the utility model that whole cleaning process is controlled, specific as follows:
(1) use 100-500 microlitre adjustable pipette 4 accurately to pipette 500 microlitre 0.5mol/L sodium hydroxide solutions (standard solution) in micro-test solution bottles 7, add 1 methyl orange indicator to shake up, standing.
(2) get mixed liquor in a certain amount of cleaning process, in standard solution, the limit edged shakes up with this mixed liquor of adjustable pipette 4 accurate measurings, until that the color of standard solution is become by yellow is orange red, record adds the total amount of mixed liquor, can obtain the acidity of clean-out system.
When with adjustable pipette 4 accurate measuring 700 microlitre mixed liquors in standard solution, add shaking up after complete, orange red if the color of standard solution does not become, show that clean-out system lost efficacy, need to continue add good fortune generation Tyke clean-out system, otherwise show that clean-out system is still effective, continue to clean.
Under clean-out system still effective situation, use pipettor successively quantitatively to add mixed liquor according to the accurate addition reference value of dilution ratio before cleaning and laboratory and (please follow on a small quantity repeatedly principle when adding mixed liquor, it is excessive to be sure not once to add) until that the standard solution color becomes is orange red, record adds the mixed liquor total amount, when twice of front and back interpolation total amount is identical, incrustation scale is described, and removing is clean substantially, continues wash cycles and can finish after half an hour to clean.
