In, allow student's intuitively observation experiment phenomenon, understanding of the student to this respect knowledge can be deepened, beneficial to memory and the skilled palm
Hold.In middle school chemistry, classroom is tested sometimes for the multiple of same condition are carried out, when single experiment is carried out successively, due to many
Secondary operation, is easily caused the accumulation of error, so as to cause experimental data misalignment；And test simultaneously, due to individual different, same error
It is larger；Thus being badly in need of one kind can once carry out multiple parallel laboratory tests, reduce human factor error, the embodiment experiment of objective
The instrument of result.
The content of the invention
The purpose of this utility model is to solve the weak point that prior art is present, there is provided a kind of reasonable in design,
It is easy to use, be easy to paired observation parallel laboratory test instrument.
In order to achieve the above object, parallel laboratory test instrument described in the utility model is divided into two parts, respectively stores
Liquid device and reaction unit, wherein sump assemblies are separatory funnel type, and reaction unit is test tube type container, sump assemblies and reaction
It is parallel to each other between device and reaction unit and reaction unit, by connecting pipe vertical connection, connecting pipe is located at a point liquid leakage
Between separatory funnel stopcock and waste liquid the discharge piston of bucket shape device lower end, connecting pipe tail end is salable；According to parallel reaction
Number, reaction unit can be set corresponding quantity, same between reaction unit to be connected by connecting pipe, adjacent two-by-two.
Instrument of the present utility model can：
1st, while carrying out the n experiment of sample (n >=1)；
While can effective observing response phenomenon when the 2, carrying out multiple experiment.
In certain embodiments, the reaction unit bottom is additionally provided with reaction controlling piston.
In certain embodiments, the material of the parallel laboratory test instrument is clear glass.
In certain embodiments, the connecting pipe is glass connecting pipe.
In certain embodiments, the test tube type reaction unit is provided with branch of the bore less than upper port at upper port
Pipe.
In certain embodiments, the test tube shape reaction unit upper port is ground setting, can be sealed.
A kind of middle school chemistry parallel laboratory test instrument of the present utility model, design is very reasonable, when needs carry out multiple in fact
When testing, sump assemblies lower end separatory funnel stopcock is closed, reaction reagent is added toward sump assemblies, such as acid；With another kind of
Reaction solid material is put into reaction unit from left to right respectively, such as metal；Waste liquid discharge piston is closed, reaction unit is opened
Reaction controlling piston；Finally open separatory funnel stopcock so that reaction reagent is into being reacted in reaction unit.
