Ohaus STMP4AL Multi-Position Stirrers

The Ohaus STMP4AL is designed for simultaneous mixing of multiple liquid samples in laboratory settings. It is commonly used for titrations, dissolution studies, and reagent preparation, where consistent and uniform stirring across multiple vessels is required.

This model features four independent stirring positions, allowing users to mix up to four containers (typically up to 1 L each) at the same time. This makes it ideal for increasing throughput in busy lab workflows.

The stirrer offers an adjustable speed range of approximately 60 to 1400 RPM, with microprocessor control to maintain stable and consistent stirring performance throughout operation.

The unit is built with a cast aluminum housing and a glass-filled nylon top plate, providing excellent chemical resistance, durability, and easy cleaning. This makes it suitable for demanding laboratory environments where spills and exposure to reagents are common.

The STMP4AL includes a speed ramping function that gradually increases stirring speed to prevent splashing and improve magnetic coupling. It also offers precise speed control and stable operation, ensuring reproducible results across all positions.
