Wellwash@ AC

Wellwash AC guarantees excellent washing performance and low residual volumes for 96-well microplates in research or high-throughput applications.

Superb washing performance

Washing performance is excellent. Residual aspiration volumes alter the washing cycle are less than 1 PI per well when the advanced sweep aspiration is used. During the advanced sweep function, the wash head moves in quick steps instead of scraping the bottom of the well.

Rapid washing

The twin-strip wash head of the Wellwash AC rapidly traverses the stationary plate during washing. The design also provides the quickest and safest way to change the wash heads, with a choice of double 24­or 16-way and single 12- or 8-way formats.

Enables reduced soaking times

Wellwash AC features an integrated orbital shaker with programs to adjust the duration of shaking and the speed, depending on the volume of the liquid in the wells. Shaking during a soak period improves sensitivity, specificity and precision of an assay; thereby, shorter soaking times can be used.

Unique multibuffer module

Wellwash AC is a multibaffer microplate washer with its own separate liquid management mod­ale. Switching to liquid purging is fully automated, ensuring secure wash baffer changes. Unique quick-release bohle caps house the liquid-level sensing system, which provides audiovisual warnings.

Minimal setup time

Wellwash AC has automatic rinsing and priming modes that can also be activated on demand. The use­ful stand-by function of Wellwash AC partially flushes the wash heads with rinsing solution and parks the wash head in the priming vessel that contains rinsing solution. In this way, Wellwash AC is ready for use whenever needed, with a minimal setup time.

Easy-to-use programming

Wellwash AC provides the easiest and most flexible programming. The easy programming is based on a question-and-answer format, allow­ing control over all wash parame­ters. A special feature is the ability to include additional dispensing of a second baffer alter the complete washing protocol, within the saure program. A total of 99 wash assay programs, each wich up to 4 linked protocols, can be stored.

Robot compatibte

Therrno's Wellwash AC offers labo­ratories additional capacity through its easy robot compatibility. Plate handling devices for stacking and transferring plates can be used to increase flexibility and improve throughput.

LQ/OQ/PQ

The Instrument qualification IQ/OQ/PQ Protocol Bock is avail­able for the Wellwash AC. For fur­ther Information about the features of the IQ/OQ/PQ, See page 52.
