Top performance with unique co-axial wash heads
With their proven design, the co-axial wash heads of the Wellwash 4 Mk 2 ensure excellent washing efficiency and low residual volumes of less than 5 µl. For clean delivery of washing buffer, the inner dispensing tubes are made of stainless steel. A continuous vacuum in the outer tube prevents cross-contamination and ensures complete liquid removal. Switching between the 8- and 12-way wash heads takes just a few seconds.

Quick and easy programming
For fast and accurate selection of routine protocols, the Wellwash 4 Mk 2 comes with four standard program cards (1-4 washing cycles). It is also available with a programmable card. Developed for user-defined programs, this card permits a quick selection of all wash parameters, including soak times and final wash protocols. A programmable dispensing volume of up to 750 µl enables effective removal of proteinaceous material in a top-washing process.

Effective liquid management
The quick release bottle caps of the Wellwash 4 Mk 2 ensure easy buffer changes. An additional rinse bottle can be connected, making it easier to purge wash buffer from the wash head or change to a different wash buffer. Automatic pump shutdown, another useful feature, reduces wear and noise levels. If unused for 30 seconds, the wash pump of the Wellwash 4 Mk 2 automatically switches off.

The Wellwash 4 Mk 2 microplate strip washer includes all needed bottles and accessories for EIA assays.
