MJ-A style drop-on-demand single jet dispensing devices are suited for dispensing droplets of aqueous and solvent-based fluids at up to 50°C. An integrated orifice and wetted surfaces that are almost exclusively glass make MJ-A devices extremely robust to aggressive fluids. Orifice diameters of 20-80um are available, allowing customers to optimize their process by selecting drop volumes within a two order of magnitude range. Fluids with viscosity less than 20 cPs and surface tension in the range 20-70 dynes/cm can be dispensed.
Three fluid fitting styles are available: barbed, threaded, and Luer.
The threaded fitting is intended for use with PTFE tubing. The Luer fitting contains an integrated, removable filter.
The integrated orifice extends from the housing, allowing visualization of both internal flow and drop formation. The orifice can optionally be protected from damage by metal extensions on two sides.
Custom, application-specific configurations can also be developed.
