Wash Head

The wash head on the Opsys MW™ Microplate Washer contains multiple sets of dual wash pins. Each set of dual wash pins consists of a dispense pin and an aspirate pin that are closely spaced so that fluid can be aspirated from and dispensed into a well simultaneously.

The following wash heads can be fitted on the Opsys MW™:

	Wash Head		Description
	1 x 8		Eight sets of dual wash pins for washing a 96-well


			microplate one column (8 wells) at a time.
	1 x 12		Twelve sets of dual wash pins for washing a
			96-well microplate one row (12 wells) at a time.

If a wash head is installed to wash plates by columns, the plates are placed on the instrument so that the columns of the plate are aligned with the wash head. If a wash head is installed to wash plates by row, the plate is rotated 90 degrees and placed on the instrument so that the rows of the plate are aligned with the wash head.

The wash pins are fixed to the wash head. During operation, the wash head assembly is lowered to insert the wash pins into the wells or raised to remove the wash pins from the wells. Lowering the wash head assembly allows the well contents to be aspirated or a bottom wash to be performed. Raising the wash head assembly allows the plate to be moved so another column (or row) can be washed or so the wells can be filled.
