What is the Mya Control Pad? Your Mya 4 Reaction Station will come with its own Control Pad, supplied as standard with every unit. This is intuitive and easy to use, using a very small footprint. Using the Control Pad, you can set automated profiles or use manual control. It allows for single or multi-user operation. You can quickly and easily control the heating, active cooling and stirring of each zone independently. The Control Pad will control and record all data on temperature and stirring in your experiments.
