Introducing the Fastest Microplate Washers

Introducing the Fastest Microplate Washers


Berthold Technologies offers high-end 96-channel microplate washers for 96 and 384 well with or without automated microplate loading by built-in stacker. With the addition of the Dispense Module, the microplate 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 washing of ELISA assays, with the task of separating unbound label from bound analyte-label complexes.

Zoom HT LB 920 Microplate Washer

Zoom HT LB 920 Microplate Washer

The Microplate Washer Zoom HT is robust, easy-to-use and designed for High Throughput. Unmatched speed is the result of the integrated stackers and one-rail design. This washer will process both 96 and 384 well microplates using the same wash head.

A unique and self-emptying vacuum system provides constant flow rates.

With the addition of the optional Dispense Module, Zoom HT becomes a fast and efficient washer-dispenser-stacker combination instrument.


Zoom HT LB 920 Applications

  • Microplate coating
  • ELISA assays
  • ELISPOT assays



Zoom HT LB 920 Highlights


Its one-rail design combines wash and stacking positions, greatly reducing the time needed to move the plates from the stacking position to the washing position.

  • 96 well plate: wash 3 x 300 µL: 17 sec; wash 3 x 300 µL + stack: 24 sec
  • 384 well plate: wash 3 x 75 µL + stack: 44 sec


  • 96 & 384 well (no change of wash head necessary)
  • built-in microplate stacker
  • stand-alone (no PC required) with preconfigured programs
  • virtually no residual volume due to 3-D aspiration
  • buffer selection (up-to four different buffers/liquids in one process)
  • add-on: Dispense Module

High-performance microplate washing is needed in a wide range of methods in the field of Life Sciences:

  • Performing ELISA assays requires fast and efficient microplate washing. Assay reproducibility and consistency between wells are of utmost importance, making automated washing very desirable. In addition, the use of a fast microplate washer reduces assay time.
  • ELISA microplate coating for assay production (either for manufacturing or for own use in labs performing many ELISA assays per day) usually requires accurate dispensing and very fast microplate washing, in order to achieve a high throughput and consistency between wells. In this case it is also important to have automated plate handling, for example a microplate stacker, to increase the throughput.
  • 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.

Automated microplate washing is a challenging process. The most important challenges are:

  • Reliable handling of troublesome ingredients: the reagents used in microplate coating can be troublesome, as they may clog the thin needles typically found in microplate washers, or produce large amounts of foam.
  • Low residual volume: this is of utmost importance in the case of microplate coating when removing the blocking reagent, as any remains would interfere in the assay to be performed in the microplates, but also in any washing protocol.
  • Gentle washing in the case of cell washing, as already mentioned. This may also be important in some ELISA assays, if the attachment of the coating to the microplate is weak.

Our Zoom HT Microplate Washers are able to accomplish all of this and much more, thanks to their high performance and flexibility. They can wash both 96-well and 384-well microplates without any hardware changes, as the same wash head is suitable for both microplate types.

Why is the Zoom HT Microplate coating system ideal ?

The Zoom HT Microplate Coating System is the ideal washer-dispenser for ELISA coating. The system is robust, easy-to-use and designed for speed and throughput. The unique built-in microplate stacker shuttles the plates seamlessly between storage and wash positions. This washer-dispenser will process both, 96 and 384 well microplates using the same wash head. Its Dispense Module allows the precise dispensing of reagents with minimal dead volume (important for adding antibodies, antigens and other valuable reagents).


Zoom HT LB 920 Microplate Coating System Applications

Plate Coating (ELISA coating)

Plate coating in the Life Sciences means the immobilization of the well surface with antibody, antigen, or any other compound valuable for diagnostic purposes. The coated plate is part of any manufactured ELISA kit, or it is used in „home-brew“ ELISA assays. Thus the term ELISA coating is often used.
