Magnetic Stirrer MS-C-S4 (4-Channel) (CAT#: STEM-BC-1788-ZJF)

The MS-C-S4 is a compact magnetic stirrer designed for continuous and efficient mixing of liquid samples in standard laboratory vessels. It employs a strong permanent magnet assembly to drive a PTFE-coated stir bar placed inside the vessel, producing consistent fluid motion without direct mechanical contact. The brushless DC motor provides smooth, quiet, and maintenance-free operation across the full speed range. A uniform parallel magnetic field ensures consistent stirring performance regardless of stir bar position on the working surface. The chemical-resistant working plate is constructed to withstand spills of common laboratory solvents and reagents. Speed is adjusted via a rotary dial or digital interface, depending on the model, allowing precise control. The instrument is suitable for low-viscosity liquid mixing, dissolution, and routine sample preparation. Its compact footprint makes it appropriate for bench-top use in space-constrained laboratory environments. The unit is compatible with a wide range of vessel types including flasks, beakers, and bottles. It is commonly used in chemistry, biochemistry, pharmaceutical, and educational laboratory settings.
