Abstract
The utility model relates to a double burette. The utility model is characterized in that a supporting beam is arranged between two burettes, and the lower end of each burette is additionally provided with a rubble hose with a rolling ball. The utility model has simple structure and small testing result error, the utility model can be singly used as well as be used through combination, being suitable for the titration of alkaline solution.
Description
The utility model relates to a kind of titrimetry device.
Present laboratory is carried out titrimetry and is adopted the single tube titration mostly, act composition to be measured in prophet's sample definite percentage composition scope and be equipped with the certain density titer (vs) that adapts with it, make it to satisfy the requirement of titration error, thereby reach the purpose of detection.Same component content differs very big titration determination in difference product or the several sample of the same race but if do, then the titer of single hose titration can make that reading is low or high can not to satisfy error criterion because of its determinacy, and single tube titration workload is big like this, efficient is low, poor reliability, the titer waste is big.
The purpose of this utility model is the deficiency that overcomes foregoing invention, provides a kind of titration accurate, two formula burets that efficient is high.
Technical solutions of the utility model are to be made of at brace summer, mozzle between two-tube two burets and frame, and its principal feature is to be provided with the elastic hose that contains ball between each buret and the mozzle.
The utility model is simple in structure, and cost is low, the accuracy height, and titration test result error is little, saves reagent, is particularly suitable for the alkaline solution titration.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the utility model structural representation.
Fig. 1,2 burets, 3 brace summers, 4 balls, 5 elastic hoses, 6 mozzles.
Two burets 1,2 are set up a rubber hose that contains the glass ball by brace summer 3 support fixation between each buret 1,2 and mozzle 6.During the titration test, can in two-tube 1,2, adorn sample of the same race, also can adorn the xenogenesis sample, if need to use pipe 1 or managed 2 o'clock, the ball 4 in the squeezing tube 5, titer (reagent) can flow out, and the time spent does not unclamp promptly and restores, to reach the purpose of two-tube test.
Claims (1)
1, a kind of pair of formula buret is made of at brace summer 3, mozzle 6 between two-tube two burets 1,2 and frame, it is characterized in that: have additional the elastic hose 5 that contains ball 4 between buret 1,2 and the mozzle 6.
