Hanna Magnetic Mini-Stirrer with Speedsafe

A mini-stirrer for the bench positions where a full-size plate does not fit and is not needed: inside a fume hood alongside other apparatus, in a refrigerated cabinet, on a crowded titration bench, or simply where a 1 litre beaker is the largest vessel that will ever sit on it.

Capacity is 1 litre and the speed range runs to 1000 rpm — the same top speed as the heavy-duty frame, because small vessels often need higher rpm to establish a vortex at all. Speedsafe decoupling protection is carried over: if the bar drops out of sync, the drive backs off instead of hammering it.

Two versions:

The stainless cover earns its place where spills are routine — acids, salt solutions, anything that would work into a plastic top over time. It wipes clean and does not stain. Where the stirrer lives on a dry bench, the standard version is the cheaper and equally capable choice.
