200-2000rpm Magnetic stirrer — LA155

This 200-2000 rpm magnetic stirrer is a compact and essential tool for modern laboratories. It provides reliable, motorless agitation for a wide range of liquids, from aqueous solutions to moderately viscous fluids.

Its core function is based on a rotating magnetic field. A small, Teflon-coated stir bar is placed inside the container, which sits on the unit's platform. When activated, the unit's rotating magnets beneath the platform cause the stir bar to spin, creating a consistent vortex for thorough mixing and homogenization.

The key feature is its broad speed range of 200 to 2000 revolutions per minute (rpm). This allows for gentle mixing of cell cultures at lower speeds and vigorous stirring for chemical reactions or dissolving solids at higher speeds. The unit typically includes a precise speed control knob and an intuitive interface for easy operation.

Constructed with a durable, chemically resistant top plate (often aluminum or ceramic), it is easy to clean and protects against accidental spills. Its quiet operation and compact design make it ideal for any lab bench. This versatile instrument is indispensable for tasks such as sample preparation, chemical synthesis, dissolution experiments, and heating applications when paired with a hotplate model. It is a fundamental piece of equipment for ensuring efficiency and reproducibility in research and quality control.
