Description

Liquid separation processor

Technical Field

The invention belongs to the field of laboratory instruments, and particularly relates to a liquid separation processor.

Background

Liquid separation is an operation that separates two immiscible liquids. The apparatus used for separating is a separating funnel, and the operation steps are as follows: the liquid to be separated is poured into a separating funnel by a common funnel and then is plugged. The separatory funnel is then placed on a funnel stand or in an iron ring of an iron stand (if the liquid is to be shaken, it should be shaken well and then placed). After the liquid is separated into two layers, the cock is unscrewed to make the lower layer liquid flow down from the funnel pipe, and before the cock is unscrewed, the groove or the small hole on the piston at the top of the separating funnel is aligned with the small hole at the neck of the upper opening of the funnel, or the piston at the top is taken down to be communicated with the atmosphere. Otherwise, liquid cannot flow out of the lower port through the tap. When the lower layer liquid is drained, the cock is immediately closed, and then the upper layer liquid is poured out from the upper opening of the funnel.

However, in the above operation process, the experimenter needs to hold the separating funnel to shake repeatedly and needs to deflate intermittently, which is troublesome. Meanwhile, in the process of shaking and deflating, reagents are easy to leak or topple over, so that the experiment is influenced.
