Introduction

The MICROSTIRRER magnetic stirrer is a small, simple and effective stirrer. Thanks to the white cover surface it is specially designed for microtitrations, and it is extremely useful where reliable and small instrument is needed. The stirrer stays cold even after several days of continuous use. This feature makes it highly appreciated in microbiology and biochemistry. The technopolymer structure is studied and tested in order to give to the instrument an excellent resistance to the attack of chemical agents and to corrosion in general.

NOTE: it’s important to choose the most suitable magnetic stirring bar related to the quantity and the liquid to be stirred as well as to the type of the beaker. The magnetic stirring bar that satisfies most of the application is A00001056 (6x35mm).
