PICO Toµch controller reportedly helps dispense exact, repeatable micro-deposits as small as 0.5nL at up to 500Hz continuous, with 1500Hz maximum bursts. Features intuitive touch screen interface for precise control of the valve. Can set precise operating parameters, such as ramp open and close and stroke control. Pulse time can be adjusted in increments as small as 0.01ms. Better slope control delivers more repeatable deposits, while preventing turbulence and air bubbles from entering the fluid.
