Description

A kind of titration outfit of combined type band fluid infusion zeroing function

Technical field

The present invention relates to relate to a kind of titration outfit of combined type band fluid infusion zeroing function.

Background technology

The acid base titration device is all kinds of chemistry, chemical industry, and medicine, biology, physiology, the common experimental utensil in laboratory such as biochemistry and laboratory is widely used in various experiments and chemical examination.General soda acid acid base titration pipe has following shortcomings at present; At first, the acid base titration pipe must carry out the manual work zeroing by operating personnel in use, and zeroing often need repeat repeatedly could accomplish; Because manually-operated has the eyesight error, does a test and need repeat could confirm the result several times.This just causes manpower, material resources and waste of time.Liquid level position was higher when its acid base titration pipe was installed on the workbench; Operating personnel must flush sight line during zeroing with liquid level; Operating personnel need stand up from the seat during fluid infusion in buret; The time that not only spent has also increased labor intensity of operating staff, and the shorter person of stature is more painstaking.(Zheng Yanlong, Pan Ziang write " laboratory glassware handbook ISBN:9787122001689)

Summary of the invention

In order to address the deficiencies of the prior art, the object of the present invention is to provide a kind of titration outfit of combined type band fluid infusion zeroing function.

Being constructed as follows of a kind of titration outfit with combined type band fluid infusion zeroing function provided by the invention: liquid storage bottle is the tubualted bottle of circular glass, and the plug plug is at the opening part of liquid storage bottle lower end, and there is a circular hole center of plug, and drain pipe passes the circular hole on the plug; Tube connector is a silica gel hose, and the control valve two ends are respectively thick glass tube and the glass tube that slightly attenuates, and tube connector one end is enclosed within on the drain pipe, and the other end is enclosed within the first control valve raw glass Guan Yiduan; Tube connector is a silica gel hose, and the one of which end is enclosed within an end of the glass tube that slightly attenuates of first control valve, and its other end is enclosed within an end of U type glass tube; Two holes of vertically running through are arranged on the plug, and the other end of U type pipe and an end of ell pass two holes on the plug respectively, and ell is the glass tube that burns till rectangular shaped; The plug plug is at buret place suitable for reading; One end of tube connector is enclosed within the other end of ell; Its other end is enclosed within an end of the ell of bend pipe; Bend pipe is that an end is a U type pipe for the ell other end; Both connect by kiss, and an end of U type pipe is pasting inner tubal wall and inserting in the calibrated buret, and the lower end of U type pipe is concordant with the zero graduation line of calibrated buret; Elastic rubber tube is enclosed within on bend pipe and the calibrated buret, and both are fixing together; Liquid storage bottle places on the pallet, and pallet is a stainless steel disc; The sleeve pipe upper end is welded on the tray bottom circle centre position, and its lower end is enclosed within the upper end of cylindrical support bar, and the fixed tube folder is fixed on the cylindrical support bar through fixed screw, and calibrated buret and buret are clipped in the two ends of buret clamp respectively; The lower end of cylindrical support bar is fixed on the iron stand, and iron stand is a cuboid iron plate; Receiving flask is the glass triangle bottle, is placed on the iron stand, and bottleneck is facing under the buret liquid outlet; Buret lower end caliber attenuates and is connected with the 3rd control valve; Calibrated buret lower end caliber attenuates and is connected with second control valve; First control valve, second control valve, the 3rd control valve are the standard control valve.

The use of the titration outfit of a kind of combined type band fluid infusion zeroing function provided by the invention is dynamic: assemble the titration outfit of a kind of combined type band fluid infusion zeroing function provided by the invention.First control valve 18, second control valve 19,20 3 control valves of the 3rd control valve are transferred to closed condition, fill solution toward liquid storage bottle 1 then, open first control valve 18; Solution in the liquid storage bottle 1 enters into buret 17 through drain pipe 3, tube connector 4, first control valve 18, tube connector 14 and U type glass tube 11 successively; When liquid level in the buret 17 reached ell 10 lower ends, liquid level no longer rose, but entered into calibrated buret 13 through ell 10, tube connector 9 and bend pipe 8; Liquid level constantly rises in the observation calibrated buret 13; When liquid level surpasses the zero graduation line, close first control valve 18, fluid infusion this moment finishes; Open the 3rd control valve 20, then the above liquid of zero graduation line is drawn out of in the calibrated buret 13, like Fig. 3 when seeing that bend pipe 8 lower ends begin to have the bubble entering; This moment, liquid level was just in time located at zero point; And liquid level just in time is lower than bend pipe 8 lower ends, and solution no longer get into bend pipe 8 in the calibrated buret 13, changes as air to begin to get into; Close the 3rd control valve 20, this moment, zeroing finished; Then, then open second control valve, 19 titration testing samples; Repeat aforesaid operations when dripping next sample; When withered, the solution that is oozed by buret 17 is refunded liquid storage bottle 1 with solution after getting in the receiving flask 21 again, and receiving flask 21 is put back to the origin-location then.

Beneficial effect: the titration outfit of a kind of combined type band fluid infusion zeroing function provided by the invention.Because three control valves are all in the lower end, the operator is seated just can accomplish the operation of fluid infusion, zeroing, titration.Have simple to operate; Reduce the eyesight error greatly, can make liquid level accurately remain on same zero-bit, metering accurately; Advantages such as saving funds and disassembly and assembly are convenient and swift; Liquid storage bottle is filled solution and can need not can be increased work efficiency more than 60% to wherein fluid infusion by hundreds of samples of titration, reduces labour intensity more than 80%.
