The Post Air-Gap is best utilized when aspirating liquids with a low surface tension
(Methanol for example). The post air gap will provide a bu er between the liquid and
the tip ori e. This well help slow, or prevent, the liquid from leaking prematurely.
An Empty command will purge the Air-Gap and the Liquid. Pre and Post-Air Gaps can
be combined within a function.
The Tip-Touch function can be utilized to help prevent post-dispense hanging-drops,
thus providing a complete dispense. It is very useful for dispensing into a dry plate.
Slowing the plunger speed can improve results when working with viscous materials.
The slower speed allows the natural capillary action of the tips to work more
e
iently.
The Dwell Time setting is useful for accurately Aspirating/Dispensing viscous
material. Dwell Time is de ned as the amount of time the tips stay in position after
liquid handling functions. Similar to slowing the Plunger Speed, a longer Dwell Time
allows capillary action to work more e
iently. This setting is usually located in the
CONFIG or SETUP les of applicable Software.
