R18 overhead stirrer is a long lasting stirrer suited for all stirring needs of moderate viscosity in any laboratory, either professional or classroom. Due to their slim design they are well suited for series of tests.
The use of the instrument is advantageous where the speed adjustment of stirring processes has to be reproducible -such as when test series have to be carried out one after the other under comparable conditions, and when parallel experiments with several stirrers must be made simultaneously. With electronic feed speed control suitable for stirring a liquid mixture, up to 20 lit. It provides the required mechanical energy, necessary for the emulsions composition, as well as the dispersal of substances to create dispersions. Ideal for low viscosity liquids (100-1000 mPa · s). The speed may be gradually adjusted from 110 to 2000 rpm. Built-in security circuit. It shall not block, while at the same time providing an indication and protection in case of overloading. The electronic feed-back type of control guarantees exact control and high precision so fluctuations in the viscosity of the media being stirred will not occur.
The stirrer has a hollow shaft with a 10.5 mm bore and a heavy chrome plated chuck to avoid corrosion.
The economic and powerful stirring motor for every days lab work.
