The IceCap Magnetic Aquarium Test Kit Mixer replaces shaking or swirling test vials by hand with a magnetic stir bar and motorized base — drop the stir bar in, set the vial on the base, and press the button. USB rechargeable with a 120-minute battery life per charge. Power: USB 5V, 1 watt, rechargeable Battery life: 120 minutes per full charge Auto-shutoff: after 5 minutes per use to conserve battery Max vial size: 1in diameter (27mm); includes a 10mL vial Dimensions: 2.375in height, 2.75in x 2.5in footprint Consistent mixing matters more than it seems for accurate test results — 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.Compatible with: most standard test kit vials up to 27mm diameter.
