Magnetic Stir Plate with accessory arm
This stir plate will fit up to a 2000 ml flask. Features a pH probe holder (not for use in the 1000ml or 2000ml flasks, but a shorter jar with a sample). The stir plate features an on/off switch as well as a speed control dial, and a screw-in fuse in the back. Comes with magnetic stir bar. Really useful for growing up yeast cultures. A constantly-stirred yeast starter will yield a much higher cell count than a non-stirred starter.
