Thermal demand mode ink-jet technology systems can achieve extremely high fluid dispensing performance at a very low cost.Since piezoelectric demand mode ink-jet technology does not require recirculation of the working fluid, does not create thermal stress on the fluid. heavy duty racking This type of printer is usually referred to as a thermal ink-jet printer.Ethylene glycol from a device with a 50μm orifice at 2,000 per second. Demand mode ink-jet printing systems produce droplets that are approximately equal to the orifice diameter of the droplet generator. light duty racking As Figure 3 indicates, demand mode systems are conceptually far less complex than continuous mode systems. On the other hand, demand mode droplet generation requires the transducer to deliver three or more orders of magnitude greater energy to produce a droplet. medium duty racking One of the characteristics of ink-jet printing technology that makes it attractive as a precision fluid microdispensing technology is the repeatability of process. The images of droplets shown in Figure 2 and figure 4 were made by illuminating the droplets with an LED that was pulsed at the droplet generation frequency. pallet racking The exposure time of the camera was ~1 second, so that the images represent thousands of events superimposed on each other. The repeatability of the process results in an extremely clear image of the droplets, making it appear to be a high speed photograph. steel pallet To further illustrate this point, Figure 5 shows two 60μm diameter jets of water breaking up into 120μm diameter droplets streams at 20,000 per second, and being caused to merge into a single droplet stream. Again, this image was created using a “strobed” LED and a ~1 second exposure time. steel work bench Not only is the droplet formation process so repeatable that the image of the droplets is sharp, but when the droplets are caused to merge, the formation of the highly contorted merged droplets is, principally for product labeling of food and medicines seen to be just as repeatable. SEO Service Continuous mode ink-jet systems are currently in widespread use in the industrial market. They have high throughput capabilities, especially array continuous mode systems, and are best suited for high duty cycle applications. Few continuous mode ink-jet systems are multicolor, but two color systems are in use. SEO Services Because they require unused drops to be recirculated or wasted, the potential for using continuous mode ink-jet technology in biochemical processes is limited, particularly in processes where many fluids need to be dispensed. ink jet All of the results and potential applications discussed in this chapter will be based on piezoelectric demand mode ink-jet technology.Advantages of Ink-Jet Dispensing. The ability to dispense 25-100μm droplets using ink-jet technology equates to a single droplet volume resolution of 10pl to 0.5nl. [Note that this range represents the design space of dispensing systems, not the operating space of a specific system.RJY
