Pipettor
head
Contains 6 high-precision syringe pumps, each containing
a tip adapter which attaches to filter-tips. Each tip aspirates
and dispenses 50–1000 μl liquid.
Pipetting accuracy is as follows:
 50–100 μl ± 5%
 100–1000 μl: ± 2%
Syringe pumps are air-filled.
Liquids containing salts, alcohol, solvents, and/or
magnetic particles can be aspirated and dispensed.
Air gaps can be aspirated to prevent aspirated liquid from
dripping.
The pipettor head contains a magnet that allows
separation of magnetic particles from the aspirated liquid.
Filter-tips are picked up from the tip rack and ejected back
into the tip rack.
The pipettor head moves in the Z direction above the
worktable.
Heating
system
Accommodates the heating positions of reagent cartridges
and has a temperature range of between ambient
temperature and 95ºC (203ºF).
Heating block accuracy at 60°C is ± 2°C.
Filter-tips Attach to the tip adapters of the pipettor head to allow
liquid aspiration and dispensing. Capacity of 50–1000 μl.
The BioRobot EZ1 DSP accommodates up to 12 tip
holders, each containing a filter-tip, in the tip rack on the
worktable.
