AutoAqua Smart Stir

The AutoAqua Smart Stir is a compact magnetic stirrer built to mix aquarium water test reagents evenly and consistently, replacing manual vial-shaking with the press of a button. Best for: mixing reagents for aquarium water test kits (titration and colorimetric tests) Fits: standard test vials under 27mm (2.7cm) diameter Power: built-in rechargeable lithium battery, USB charging (5V, ~120 minutes to full charge) Auto-off: shuts off after 5 minutes to conserve battery; low-battery indicator included Design: non-slip rubber pads dampen vibration for quiet operation; sturdy vial holder Dimensions: 2.77in x 2.77in x 2.34in Includes: Smart Stir base, micro-USB charging cable, magnetic stirring bar, iron wire. Consistent mixing matters more than it seems for test accuracy — uneven reagent mixing is a common source of color-match errors on titration and colorimetric tests, and a stir bar mixes far more evenly than hand-swirling a vial.
