Abstract
The invention discloses a burette which is characterized in that the lower end of a burette body is provided with a purpose made titration switch so as to ensure that the burette can contain acid, alkali and other titrating solutions. The burette is quick, accurate and convenient during titration operations and is a universal burette.
Description
Technical field the present invention relates to chemically examine the titration test of bright chamber, directly relates to the titration experiments of departments such as hospital, school, factory, quality inspection.
It is traditional acid buret or base buret that used buret is tested in the current titration of background technology.Acid buret titration switch is the glass turn-knob, and is dumb in the use, and easy-to-leak liquid can not be adorned alkali lye.Base buret titration switch is that emulsion tube and glass marble are combined into, and is easily aging, easily is corroded, and can only adorn alkali lye, and extremely inconvenience and error are big in the use.
Summary of the invention purpose of the present invention will provide a kind of improved buret exactly, because it has unified the titration switch, has overcome the various shortcomings of traditional buret effectively.This buret can be adorned acid, also can adorn alkali and other solution, makes the convenient and easy of titration operation change, quick and precisely.
The object of the present invention is achieved like this, and buret has body and switch, and body is the glass tube that indicates scale, and switch is that corrosion-resistant plastic is made the pulley rolling formula, is convenient to very much control flow velocity, flow.
Improvement project of the present invention is: pulley rolling formula switch owing to improved the switch of traditional buret, makes buret become the titration all purpose instrument, save raw material, reduced cost, be convenient to large-scale production, the more important thing is that to make the titration operation simple, quick and precisely.
Appended drawings is a structure principle chart of the present invention, and the invention will be further described below in conjunction with accompanying drawing.
Specific embodiment accompanying drawing shows the structure of buret, and top is titration pipe shaft 1, and the bottom is a titration switch 2, titration pipe shaft 1 is for indicating the glass tube of scale, titration switch 2 is a pulley rolling formula switch, uses the thumb propelling sheave during use, can easily control flow rate.
Claims (3)
1. a buret is characterized in that: have titration pipe shaft (1), lower end connection titration switch (2).
2. buret according to claim 1 is characterized in that: titration pipe shaft (1) is the scale glass tube of long 600-700mm, diameter 12mm-14mm, and its capacity has 10mL-50mL.
3. according to right 1 and 2 described burets, it is characterized in that: described titration switch (2) be corrosion-resistant plastic make have a pulley rolling formula.
