The DMS4 LCD Glass Ceramic Magnetic Stirrer with Timer is a compact laboratory magnetic stirrer featuring a corrosion?resistant glass?ceramic work plate, brushless DC motor, precise LCD display, and built?in timer for accurate mixing and timing control in small?volume experiments.
The DMS4 LCD Glass Ceramic Magnetic Stirrer with Timer combines stable magnetic stirring and intuitive digital control for reliable laboratory mixing. It includes a durable glass?ceramic work surface that resists chemical corrosion and high temperatures, backed by a maintenance?free brushless DC motor that delivers smooth, quiet stirring across a wide speed range up to approximately 1500?rpm. The high?resolution LCD clearly displays speed and time settings, while the programmable timer lets you set runs from minutes to hours for unattended mixing tasks. Designed for volumes up to about 10?L, this stirrer is ideal for chemistry, biology, and general research applications requiring precise, consistent agitation with convenient timing control.
