Dispense Processing Patterns
When dispensing to high-density plates, 384- and 1536-well, 8-channel dispensers,
like the (non-RAD) Peri-pump cassettes and certain Syringe dispensers, employ a
dispensing pattern that permits filling only a portion of the plate, skipping some
sections.
n 8-channel dispensers include the Peri-pump, 96/384-well Wash manifold, and
the 8-tube Syringe dispenser manifold.
Columns
To skip an entire column toggle the radio button off. With this feature you can
dispense to odd columns in one dispense step, change fluids or use another
dispenser and dispense to even columns in another dispense step.
Rows
8-channel dispensers offer another way to control the dispense pattern to high-
density plates. See 8-Channel Dispense Patterns.
32-Tube Syringe Dispenser Manifolds
One 32-tube dispense manifold addresses one column at a time. When both 32-tube
manifolds are used simultaneously, they align with every 5th column, in a pattern
like this:
Columns
1 5 9 13
2 6 10 14
3 7
4 8 and so on...
Syringe A Syringe B
Columns 1 and 5 are dispensed to first, then columns 2 and 6, 3 and 7, and so on.
