1. Introduction

The MST 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.
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).
