Abstract

The utility model discloses a burette with graduation magnifying and auxiliary liquid adding functions, which relates to a burette. The burette with graduation magnifying and auxiliary liquid adding functions solves problems that an existing burette can easily cause eye fatigue and reading errors, affects operation speed, requires liquid added in a poured manner, is complicated in operation procedure, affects work efficiency and wastes standard liquid. The burette with graduation magnifying and auxiliary liquid adding functions comprises a burette body (1), a graduated ring (2), a magnifier (3), a guide tube (4) and a syringe (5), the graduated ring (2) is slidably sleeved on the burette body (1), the magnifier (3) is fixed onto the graduated ring (2), a liquid injecting opening (1-1) is arranged on the wall of the upper end of the burette body (1), one end of the guide tube (4) is hermetically connected with the liquid injecting opening (1-1), and the other end of the guide tube (4) is connected with the syringe (5). The burette with graduation magnifying and auxiliary liquid adding functions is applicable to chemical analysis procedures.

Description

Has the buret that amplifies scale and auxiliary liquid feeding function
Technical field
The utility model relates to a kind of buret, is specifically related to a kind of buret that amplifies scale and auxiliary liquid feeding function that has.
Background technology
Buret is one of device important in the chemical analysis, vertically places the reading with the contrast of the scale on liquid level tangent point and the buret during use.The liquid level tangent point often is between two scales, relies on estimation to be difficult to pin-point reading.When observing scale,, especially, be prone to cause asthenopia and reading mistake, influence service speed light bad place or the relatively poor operator of eyesight for the operator.In addition, existing buret need pour into liquid feeding, and operating process is loaded down with trivial details, influences operating efficiency, and the waste titer.
The utility model content
The purpose of the utility model is to be prone to cause asthenopia and reading mistake in order to solve existing buret; Influence service speed, in addition, existing buret need pour into liquid feeding; Operating process is loaded down with trivial details; Influence operating efficiency, and have the problem of waste titer, and then a kind of buret that amplifies scale and auxiliary liquid feeding function that has is provided.
The technical scheme of the utility model is: have the buret that amplifies scale and auxiliary liquid feeding function and comprise the buret body; Have the buret that amplifies scale and auxiliary liquid feeding function and also comprise calibration loop, magnifying glass, conduit and syringe; The calibration loop slip cap is contained on the buret body, and magnifying glass is packed on the calibration loop, has liquid injection port on the upper end tube wall of buret body; One end and the liquid injection port of conduit are tightly connected, and the other end of conduit is connected with syringe.
The utility model compared with prior art has following effect: 1. calibration loop 2 of the utility model and magnifying glass 3, and reading is accurate, conduit 4 and syringe 5 auxiliary liquid feedings, operating process is simple, high efficiency, and avoided the waste of titer.2. the utility model is simple in structure, and is easy to use.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model; Fig. 2 is the enlarged drawing of Fig. 1 at the A place.
The specific embodiment
The specific embodiment one: combine Fig. 1 and Fig. 2 that this embodiment is described; The buret that amplifies scale and auxiliary liquid feeding function that has of this embodiment comprises buret body 1; Have the buret that amplifies scale and auxiliary liquid feeding function and also comprise calibration loop 2, magnifying glass 3, conduit 4 and syringe 5; Calibration loop 2 slip caps are contained on the buret body 1, and magnifying glass 3 is packed on the calibration loop 2, have liquid injection port 1-1 on the upper end tube wall of buret body 1; One end and the liquid injection port 1-1 of conduit 4 are tightly connected, and the other end of conduit 4 is connected with syringe 5.
The multiplication factor of the magnifying glass 3 of this embodiment is 5~10 times.
The specific embodiment two: combine Fig. 1 and Fig. 2 that this embodiment is described, the buret that amplifies scale and auxiliary liquid feeding function that has of this embodiment also comprises a plurality of bolts 6, and calibration loop 2 is slidingly installed through a plurality of bolts 6.So be provided with, be convenient to calibration loop 2 moving on buret body 1.Other composition is identical with the specific embodiment one with annexation.

Claims (2)

1. one kind has the buret that amplifies scale and auxiliary liquid feeding function; It comprises buret body (1); It is characterized in that: have the buret that amplifies scale and auxiliary liquid feeding function and also comprise calibration loop (2), magnifying glass (3), conduit (4) and syringe (5); Calibration loop (2) slip cap is contained on the buret body (1), and magnifying glass (3) is packed on the calibration loop (2), has liquid injection port (1-1) on the upper end tube wall of buret body (1); One end of conduit (4) and liquid injection port (1-1) are tightly connected, and the other end of conduit (4) is connected with syringe (5).
2. according to the said buret with amplification scale and auxiliary liquid feeding function of claim 1, it is characterized in that: have and amplify scale and assist the buret of liquid feeding function also to comprise a plurality of bolts (6), calibration loop (2) is slidingly installed through a plurality of bolts (6).
