SU378247A1 - DEVICE FOR TRANSFERRING IMMEDIATED SOLUTIONS AND SOIL SUSPENSIONS - Google Patents

Description

one

This invention relates to devices used in the agrochemical service and. Ё Chemical Laboratories x.

The known devices, including several containers in the form of flasks, allow the transfer of the diluted solutions and soil suspensions by repeatedly using washing liquids.

The purpose of the invention is to maintain the original density of the solution.

This is achieved by the fact that the lower base of the tube is made in the form of a funnel, the inner surface of which serves as a continuation of the conical part of the container.

The drawing shows the proposed device.

It contains a tank / s sample to be analyzed, a rubber stopper 2 with a funnel-shaped notch and two openings, a thin air supply tube 5, a glass or metal drain tube 4, a rubber tip 5 and a clamp b.

The device works as follows.

The container / s of the sample being analyzed is closed with a stopper 2, into which the air duct tube 5 and the drain 4 with a rubber tip 5 and a clamp 6 are inserted.

The device is turned upside down to settle the suspensions in the conical part of the plug.

After sedimentation of the main mass of sediments opens the clamp b, and the suspension is drained. Remaining on the bottom and walls of the tank, the suspension is washed off with the clarified part of the solution with slight agitation. At this point, clamp B is closed. Repeatedly repeating this operation allows you to fully transfer the diluted solution or soil suspension from one container to another, while maintaining the density of the transferred sample.

Subject invention

A device for transferring the turbid solutions and soil suspensions, including a container with a conical upper part and a stopper, characterized in that, in order to preserve the initial density of the solution, the lower base of the stopper is designed as a funnel, the inner surface of which serves as a continuation of the conical part of the container.
