The PH-05a drop-on-demand printhead is designed for dispensing oxygen and/or water sensitive materials at temperatures up to 240°C. Integrated heated inert gas injection is used to creating a local inert environment at the orifice of the dispensing device and around the drop in flight.
The PH-05a uses the same interchangeable high temperature dispensing device, the MJ-SF, as does the PH-04a Polymer Jet™ printhead. Drop volumes ranging from 5 pL to as high as 0.5 nL have been dispensed. Using MicroFab’s patented drive waveforms, the range of the drop volume obtainable without changing the dispensing device can be a factor 3 or better.
Operation to 240°C; 30 mL capacity stainless steel reservoir; separate heaters for reservoir and dispensing device, allowing different operating temperatures; compatible with Jetlab® 4xl, Jetlab® 4xl-A, and Jetlab® II.
MJ-SF devices available in orifice diameters 10-80µm.
