Abstract
The utility model belongs to a miniature chemical experiment device, disclosing a minisize acid-form titration and separation two-way tube. The utility model is suitable for carrying out neutralized titration to acid liquor of the taking amount of 4 ml and within 4 ml and separating experiment of two liquids which are mutually not dissolved. The operation of the utility model is completely in accord with the experimental basic operation requirement of teaching program, and the minisize acid-form titration and separation two-way tube overcomes the defect that two different devices including an acid buret and a separating funnel can not used generally, which has protruding practicability for decreasing assorted devices number and reducing experimental expenses.
Description
The utility model belongs to a kind of miniature chemical experimental apparatus, and it relates to a kind of improved acid buret, particularly a kind of experimental provision that carries out acid base neutralization titration and separatory by existing chemistry teaching outline experiment basic operation requirement.
" acid buret " and " separating funnel " their volumes that chemical experiment is now used always are big, adhere to two kinds of different instruments separately, and are not general mutually.The separating funnel neck is thicker, and is bad as flow speed control, and separatory is not thorough.
The purpose of this utility model is big in order to overcome above-mentioned conventional instrument volume, the shortcoming that the necessary instrument number of packages is many, a kind of dual-purpose pipe of miniature acid titration separatory with two kinds of functions that provides.
Main points of the present utility model are that the scale mouth of pipe of 4ml acid buret is made into the standard ground, and are furnished with flat handle solid plug.
The utility model has following advantage: its volume is little, is easy to carry, and a pipe is dual-purpose, has reduced the number of packages of necessary instrument, has reduced cost.Because glass sharp nozzle tube bore is little, thereby has reduced titration error.The utility model drawing is described as follows:
Accompanying drawing 1 is the utility model, the dual-purpose pipe sectional view of miniature acid titration separatory.
The utility model is described in further detail below in conjunction with accompanying drawing 1.
(1) is the glass sharp nozzle tube in the accompanying drawing 1, is connected with piston (2) on the glass sharp nozzle tube, the flow velocity of liquid when it is used for controlling titration or divides armpit; On glass piston (2), be connected with scale socket (3), the consumption of liquid when it is used for containing vs and metering titration; Be furnished with flat handle solid plug (4) on scale socket (3), the liquid that is vibrated when it can make separatory is unlikely to be spilt.
Claims (1)
1, one by sharp nozzle tube (1), piston (2), and scale socket (3), the dual-purpose pipe of miniature acid titration separatory that flat handle solid plug (4) is formed is characterized in that scale socket (3) top of acid buret is ground, and is furnished with flat handle solid plug (4).
