Description

The DMS4?550 LCD Glass Ceramic Heating Magnetic Stirrer with Timer combines efficient magnetic stirring with accurate temperature control to support a variety of laboratory workflows. Designed with a corrosion?resistant glass?ceramic work plate, it ensures even heat transfer and easy cleaning while withstanding high?temperature applications. A brushless DC motor provides stable, low?noise stirring across a wide speed range, and the integrated LCD clearly shows set and actual values for stirring speed, temperature, and timer countdown. The adjustable timer allows users to set durations from 1?minute up to 99?hours and 59?minutes, automatically stopping heating at the end of the cycle while maintaining stirring to protect sensitive samples. Built?in safety features such as overheating protection and a ?HOT? warning indicator enhance safe operation, making this stirrer suitable for routine chemistry, biology, pharmaceutical, and QC lab tasks.
