Chapter 4 Wash Protocols

Wash Protocol Operations

Awash protocol consists of a series of Purge, Move, Soak, Aspirate, Dispense and Fill operations.

Purge, Move and Soak can be carried out in any sequence. Aspirate, Dispense and Fill can only be carried out within a Move operation, and there cannot be a Move within a Move.

Each of these operations is described below:

	Operation		Description
			Dispenses fluid from the dispense wash pins while

	Purge
			the wash head is positioned over the purge tray
			Note: Purge is usually
			carried out at the beginning
			of a wash protocol to rinse
			the dispense wash pins and
			remove air bubbles.
	Move		Performs Aspirate, Dispense, Fill and/or Soak
	Move		Performs Aspirate, Dispense, Fill and/or Soak
			operations on specified strips of the Microplate
	Aspirate		Removes the contents of a well by positioning the
			wash pins at the aspiration height in the well and
			aspirating the liquid from the wells
			A sweep may also be performed during Aspirate.
			Note: The aspirate height
			and sweep parameters for a
			particular plate type are
			specified during system
			configuration (30).
			If a sweep is specified during
			configuration, the wash pins
			are moved back and forth
			during the aspiration cycle.
