Drainage device convenient to use

Abstract

The invention discloses a drainage device convenient to use. The drainage device comprises a hydrops bottle and a drainage device, wherein the drainage device is arranged in the bottleneck of the hydrops bottle; the drainage device comprises a drainage hopper, a drainage tube and a fixing hook; the drainage tube is arranged at the mouth part of the drainage hopper; the other end of the drainage tube leans on the inner wall of the hydrops bottle; the fixing hook is arranged on the drainage hopper and hitched at the bottleneck of the hydrops bottle. The drainage device is simple in structure, safe in drainage and high in efficiency; at the same time, a plurality of drainage devices can be adopted, so that the experimental efficiency is improved.

Description

technical field [0001] The invention relates to instruments and equipment, in particular to a convenient drainage device. Background technique [0002] Chemical laboratories often use round-caliber volumetric flasks, conical flasks or flasks and other bottles or cups to hold liquid materials, especially for newly purchased experimental agents. Inappropriate leakage occurs, because some liquids are either toxic or expensive, causing unnecessary pollution and waste. A common method is to use a drainage rod for drainage, but this method is relatively cumbersome to use. It requires one hand to operate the experimental bottle and the other hand to operate the drainage rod. At the same time, too fast drainage is prone to splashing, which affects the staff and has poor use effect. Contents of the invention [0003] The purpose of the present invention is to provide a convenient drainage device with simple structure, safe drainage and high efficiency, and multiple drainage device...

Inappropriate leakage, because some liquids are either toxic or expensive, causing unnecessary pollution and waste

The common method is to use a drainage rod for drainage, but this method is relatively cumbersome to use. It requires one hand to operate the experimental bottle and the other hand to operate the drainage rod. At the same time, if the drainage is too fast, it is easy to splash, which will affect the staff and the use effect is poor.
