Compact magnetic stir plate for yeast starters, bench meters, and small-volume lab mixing.

The Milwaukee MI0040 Magnetic Stir Plate is a lightweight, easy-to-handle magnetic stirrer which is ideal for a yeast starter stir plate. With a 1 liter stirring capacity, adjustable 100 rpm - 1000 rpm speed range, and a compact round design, it is a great fit for labs, testing stations, and homebrewers making yeast starters.

This stir plate for yeast starters combines a small footprint, chemical-resistant ABS housing, and a large round speed control dial for simple day-to-day operation. It also includes a 7 x 25 mm magnetic stir bar, so it is ready to use right out of the box.

Why Choose the Milwaukee MI0040 Stir Plate?

  • Versatile use: Designed to work with Milwaukee bench and portable meters, while also functioning well as a standalone magnetic stir plate.
  • Variable speed control: Adjustable stirring speed from 100 rpm - 1000 rpm helps you fine-tune mixing performance for different liquids and applications.
  • Compact capacity: Handles up to 0.26 gallons (1 liter), making it ideal for beakers, lab containers, and 1 liter yeast starters.
  • Low-maintenance design: Built with very few moving parts to reduce wear and simplify long-term use.
  • Easy cleanup: The smooth exterior is simple to wipe clean at the end of the day.

Great for Yeast Starters

  • Perfect fit for 1 liter flasks: A 1 liter Erlenmeyer flask fits nicely on this stir plate, nesting into the recessed surface for a stable setup.
  • Larger flasks can still be used: Bigger Erlenmeyer flasks may overhang the platform but can still work with the unit.
  • SoCal Brewing Supply recommendation: If you use a larger flask, add a layer of rubber or foam to the surface to help create an anti-slip buffer and reduce the risk of spills or breakage.
  • Useful for healthier starters: Continuous stirring helps keep yeast in suspension, making this a practical option for brewers building yeast starters before brew day.
