The Microplotter II is a high-precision system ideally suited for printing electronics, novel materials, and high-resolution microarrays.
The core of the Microplotter is a dispenser that uses controlled ultrasonics to deposit fluid in a noncontact manner. This patented technology can produce picoliter droplets that form features on a surface as small as 5 µm wide. When combined with automatic surface height calibration, coefficients of variability for deposited feature diameters as small as 10% can be achieved. A wide range of fluids can be used, including aqueous solutions and many organic-solvent-based mixtures. Fluids that other dispensers struggle with, such as saturated solutions for MALDI-ToF matrices, or fluids with viscosities up to 450 cP, can be deposited with ease. The ultrasonic pumping action is also an efficient cleaning mechanism for quickly depositing many solutions sequentially.
In addition to spots, the Microplotter II can draw true continuous features, such as lines, arcs, and bends. These are uniform elements, not made from overlapping droplets like other technologies, and are particularly well-suited to the polymer electronics field
