2L Heat- Collecting Magnetic Stirrer — LA272/LA273

The 2L Heat-Collecting Magnetic Stirrer is an essential laboratory instrument designed for efficient liquid mixing and simultaneous temperature control. As its name suggests, it features a substantial 2-liter vessel capacity, making it ideal for medium to larger-scale synthesis, reactions, and sample preparation.

Its core function combines a powerful magnetic stirring system with integrated heating. A rotating magnetic field drives a sealed stir bar (flea) within the vessel, providing thorough, vortex-free mixing without external mechanical parts contacting the solution. This ensures contamination-free agitation. The integrated heating plate, typically made of aluminum or ceramic for excellent thermal conductivity, allows for precise temperature regulation from ambient to high levels (often up to 300°C or more, model-dependent). A transparent lid helps retain heat and prevent evaporation.

Key advantages include uniform heat distribution, consistent stirring even at high viscosities, user-safe operation, and easy cleaning due to a flat, seamless top plate. Advanced models offer digital PID temperature control for stability, adjustable RPM, timers, and safety features like over-temperature protection.

This versatile tool is indispensable in chemistry, biochemistry, pharmaceutical, and industrial labs for applications such as chemical synthesis, dissolution, crystallization, cell culture media preparation, and general assay procedures requiring controlled heating and mixing.
