Opsys MW™

Microplate Washer

The Opsys MW™ is an economical, full-featured 96-well

microplate strip washer. An excellent choice for many

laboratories because of its simplicity, ease-of-use, flexible

and intuitive protocol definition, and options for 12-way (row)

or 8-way (column) microplate washing for full plates or strips.

Flexibility

• The Opsys MW™ provides a surprising amount of flexibility

for its size and price.

• User-definable plate types and wash protocols provide

significant versatility.

• You can wash whole or partial plates by row or column

with interchangeable 8-way and 12-way wash heads.

• Combine prime, dispense, soak and aspirate steps in any

order, defining the duration and repetition of each protocol

step. Soak times can range from 1 to 999 seconds.

• Define, name, save and password-protect up to 10

microplate type definitions.

• Define, name, save, copy and password protect up to 40

wash protocols.

• Control how vigorously the Opsys MW™ cleans the bottom

of each well by choosing the precise wash head height and

sweep method required.

Performance

The Opsys MW™ provides consistent results with low well-

to-well variation. Sweep mode aspiration provides minimal

residual volume on flat bottom microplates.

• Dispense precision of 5% CV for 96 wells, using 300μL of

distilled water.

• Sweep mode aspiration provides a “sweeping” wash head

movement during aspiration to achieve reproducibly low

residual volumes.

• Low residual aspirate volumes of <1μL for U, V, and C

bottom microplates; and <5μL for flat bottom plates

(with sweep mode).

• On-board self-diagnostic routines automatically assure

that the Opsys MW™ is functioning properly each time it is

turned on.

Convenience

The Opsys MW™ provides key features that simplify setup,

protocol definition, operation, and cleanup.

• Compact dimensions conserve valuable bench space.

• 8-way and 12-way wash heads can be quickly and easily

interchanged to wash full or partial microplates by row or

column.

• A “show” function provides quick verification of wash head

height settings when defining a wash protocol.

• Notification to user when the waste bottle is full.

Touchpad controls are clearly marked and easy to use.
