Advantageous effect caused by the technical program is：This programme has added a glass on the side wall of separatory funnel and has led Pipe, this grass tube can ensure not will produce sealed gas chamber in conical flask when whole device is inverted, but generate one and lead to The gas chamber that grass tube is communicated with ambient atmosphere is crossed, therefore, the process that this gas chamber is flowed out in liquid from the liquid outlet of separatory funnel In not will produce pressure change, it is identical as ambient atmosphere air pressure to remain, therefore can ensure the liquid detached not It is intermittent to be released, it is no longer necessary to it is constantly inverted during traditional operation, upright the problem of going to eliminate gas chamber in conical flask, to Keep entire experimental implementation process more smooth, conveniently, for the simplicity of step also effectively smaller toxicity or corrosive liquids Flow out the risk damaged to personnel.

Furthermore grass tube its be exposed to the vertical length except separatory funnel bucket body be more than conical flask overall depth 3/ 5 and less than conical flask overall depth, be the optimal values formulated according to the accumulation of long-term experiment experience, exist under normal circumstances Liquid level after the completion of extraction and when inverted device in conical flask is not higher than the 3/5 of conical flask overall depth, therefore can protect Card the open-ended of grass tube is not blocked by liquid level, to ensure the connection of gas chamber and ambient atmosphere in conical flask.

In addition the open-ended closure for being exposed to one end except separatory funnel bucket body in grass tube has sand core, due to sand core Itself there is gas permeability, but since sand core gap is smaller therefore sand core itself has poor water penetration, the setting of sand core If can in the upright extraction stages conical flask of whole device liquid level higher than grass tube it is open-ended when avoid in grass tube Into excessive liquid, and can avoid during inversion entering excessive liquid in grass tube, and in grass tube into The a small amount of liquid entered may be used ear washing bulb and be blown out, and operation is more convenient, so as to avoid being had in whole experiment process Big quantity of fluid is gushed out from grass tube.

In addition grass tube is in smooth curved corners structure in separatory funnel bucket body, using smooth curved corners knot The corner structure that structure compares other forms can effectively prevent grass tube tube body to hang liquid, therefore can be more thorough in liquid separation, And it is convenient for cleaning of the later stage to device.
