The Opsys MW ^TM is an economical, full-featured 96-well microplate strip washer that complements the Opsys MR ^TM microplate reader. The Opsys MW ^TM is 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.

The Opsys MW ^TM is a microprocessor-controlled microplate washing system that performs wash protocols that are defined by the user. lt is designed to wash all of the wells in one column or one row of a 96-well plate at once. The washing protocol can be programmed so that all of the columns (or rows) are washed in the saure manner, or different wash cycles can be appiied to specified columns (or rows) on the plate.

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 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 you need.

Performance

The Opsys MW ^TM 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 300 µL 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 <1 µL for U, V, and C bottom microplates; and <5 µL for flat bottom plates (with sweep mode).

¨          On-board seif-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 colu nn.

¨          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.

Features

The Opsys MW ^TM system has a number of performance and convenience features. These are summarised below:

¨          Small footprint

¨          Up to 40 wash protocols can be programmed

¨          Up to ten plate types can be programmed

¨          Two wash head configurations (1 x 8 and 1 x 12)

¨          On-board seif diagnostics

¨          SHOW function allows visual verification of wash head height settings

¨          High-Ievel alarm an Waste Container

Programming

All wash protocols on the Opsys MWTM Microplate Washer are user­defined. Up to 40 wash protocols can be contained on the system.

Note:   Memory limitations may restrict the size and complexity of an individual wash protocol.

In addition, the system can be configured with up to ten different plate types so that the wash head positions for each plate type can be specified.

Programming of a new wash protocol (or modifying an existing one) and configuration of the system are carried out using the keypad and display.
