• Priming and preloading to remove air and charge fluid paths is critical to
fluid handling system performance. See "Optimizing pump performance"
(page 133) for more detail.
• Probes for aspirating and dispensing are often the most critical compo-
nent in a fluid handling system. Good probe design should follow the
same general guidelines as tubing and orifices (see above). Additional
probe-specific criteria include:
–
Contour: make all transitions in I.D. smooth and step-free.
–
Surface area: the end of the probe should have as little surface area
as possible. Keep probe end perpendicular to probe and wall thick-
ness minimized to help prevent drops from clinging.
–
Finish: both inside and outside surfaces should be free from burrs.
