Description
The Nanodrop technology aspirates and dispenses a broad range of liquids, including DMSO, and features the Nanobuilder software system that enables a wide range of applications and data manipulation. This patented technology isolates the solenoid dispense actuators from the sample path to assure long life and easy, low- cost maintenance – even with regular use of difficult suspensions such as proteins, cells and YOx beads.

Advantages of Non-Contact Dispensing
Non-contact liquid handling relies on the combined use of rapidly actuated solenoid dispense valves, a controlled pressurized liquid source, and flow path control via hybrid valves. The speed and energy of the fluid displacement enables the surface tension of the liquid to break as it leaves the orifice, eliminating the need for a touch-off. The lack of a touch-off step in the dispense eliminates the variability issues associated with touching off.
An important added benefit of non-contact dispensing is speed — the non-contact technique allows the delivery nozzle to accurately deliver the droplet above the target well and rapidly move to the next well. With the non-contact technique dispensing becomes independent of the substrate, eliminating many of the reproducibility problems associated with motion control. Plate processing times fall dramatically. Using non-contact dispensing it is possible to deliver to all wells of a 96 well plate in approximately 5 seconds, 384 wells in approximately 7 seconds, and 1536 wells in approximately 14 seconds.
