ADVANTAGES Fast liquid change Օ Contactless dispensing Single droplet volumes from 20 pl to 180 pl * Օ Variation of dispensed volume approx. 1 % * Very small storage volume Օ Very small dead volume of about 12 μl Droplet rate 1 ... 2000 Hz * (provided by a standard driver electronics) Օ Droplet velocity approx. 2 m/s * It is possible to dispense fluids with a viscosity up to about 20 mPas * Technology Features Autodrop Pipettes are based on piezo-driven inkjet printing technology. The fluid is aspirated through the nozzle tip into the glass capillary. The integrated piezo actuator induces a shock-wave into the fluid contained in the pipette, which causes a droplet to be emitted from the nozzle. Օ The inner nozzle diameter of the Autodrop Pipettes strongly influences the droplet size. The relation between inner nozzle diameter, droplet size and droplet volume is: inner nozzle diameterdroplet size in flight *droplet volume *30 Վm35 ܎m20 pl 50 ܎m55 ܎m90 pl 70 ܎m70 ܎m180 pl Criteria to find the best Autodrop Pipette ܕ What kind of fluid is to be dispensed (Viscosity, concentration of additives etc.)? > * depending on the fluid used What kind of solvent is used? Օ Are there particles in the liquid: Size and concentration of particles? The spot size on the substrate depends on the wetting behaviour between the fluid and the surface material. Օ Desired diameter of the droplets Desired droplet emission frequency Օ Dispensing volume: a) single droplet b) throughput of droplets per second microdrop Technologies GmbH are specialized in cus-tomized solutions. Please ask for application-optimized dispenser heads! Օ How many pipettes are necessary for the application? Is there an interest to upgrade the system to more than one dispenser head later? Օ Is an xyz-positioning system required?Need help? Please send us a short description of the application and a datasheet of the fluid. >
