Microplate Washer

Berthold Technologies offers high-end 96-channel microplate washer for 96 and 384 well with or without automated microplate loading by built-in stacker.
With the addition of our Dispense Module, the washers become an efficient washer-dispenser combination instrument.

Automated washing using a microplate washer provides increased speed and reliability to the process. Their most widespread use is the ELISA assay with the task of separating unbound label from bound analyte-label complexes.

High-performance microplate washing is needed in a wide range of Life Science methods:

  • Performing ELISA assays requires fast and efficient microplate washing. Assay reproducibility and consistency between wells are of outmost importance, making automated washing very recommendable.
  • ELISA microplate coating for assay production (either for manufacturing or for own use in labs performing many assays per day) usually requires accurate dispensing and very fast microplate washing, in order to achieve a high throughput and consistency between wells.
  • Washing cells growing in monolayer requires a gentle washing that does not disturb the cells. In this case it is very important to fine-tune all parameters of the washing process, such as force of aspiration, position of the dispensing, aspiration needle speed, and others.
  • ELISpot washing often requires a very strong washing to completely remove a layer of cells without damaging the membrane.

Our Zoom washers are able to accomplish all of this and much more, thanks to their high performance and flexibility.


If, in addition to washing and dispensing, you need to automate other assay steps, such as shaking, incubation and reading, you may be interested on our ELISA and Assay Workstations.
