The magnetic stirrer is an essential tool for any scientific laboratory. Among the most sought-after used models, we find the Chemland SH-7 , which stands out for its reliability and performance even after long sessions of use. This particular model is designed to be robust and compact, with a design that makes it ideal for laboratories with limited space.

Design and Visual Features

The Chemland SH-7 is visually compact and robust, with a simple but efficient structure. Thanks to its small size, it is perfect for those who work in environments with limited space. It features 4 independent positions , which allows you to conduct multiple experiments at the same time, optimizing time and resources. This feature makes it ideal for sectors such as microbiology and biochemistry, where there is often a need to mix multiple solutions in parallel.

Technical Specifications

• Manufacturer : Chemland
• Model : SH-7
• Power supply : 100-240 V, 50/60 Hz, adaptable to different electrical networks worldwide.
• Speed ​​Range : From 100 to 2000 revolutions per minute (rpm) , which offers a wide range of control over the stirring speed.
• Independent positions : 4, allowing you to work on multiple samples simultaneously.
• Key feature : The stirrer remains cold even after long hours of use, avoiding overheating and maintaining optimal temperatures for delicate analyzes such as BOD (Biochemical Oxygen Demand).

Use and Operating Procedure

The Chemland SH-7 is used to mix solutions thanks to the action of a magnetic stir bar, which moves inside the liquid under the influence of a magnetic field generated by the equipment. Use is simple: just place the container with the solvent or reagents on the stirrer, insert the stir bar and set the desired speed. The wide speed range allows mixing to be adapted to the viscosity of the liquid and the specific application.
