Proposed modification Actual designs Problems with this design: doesn't allow me to place a small sample cup (100 mL) in the water bath to stir its content. Modification: increase the base of the bath and create a double compartment with different volume of water so the magnetic stirrer has enough volume to operate while the small volume will allow to Condition samples in smaller cups. Proposed modification Designed by Raico Laria 2019-03-11 Features and benefits The stirring plate will not be in contact with the water, allowing better maintenance and replacement in case of instrument failure. This will also add more capacity to the pH meter assignment if we are able to place underneath a stirring plate with multiple positions.
