Non-contact plate washer and liquid dispenser

C.WASH™ a liquid handler tailored for your application

C.WASH™ is our innovative plate washer designed for automated, rapid and highly reproducible washing of the entire 96-, 384-, and 1536-well plates.​

The C.WASH™ uses centrifugal forces to remove liquids from well plates contact-less in seconds. Dispense the plate with liquid connected to one of the 4 liquid input channels. The angle dispensing allows aiming at well walls, hence preserving growing cells, bound capture antibodies or magnetic bead pellets.

The non-contact washing reduces the risk of carry-over and cross-contamination while saving on pipette tips.

Because of these unique properties, C.WASH™ is the perfect solution for cell-based assays and bead-based nucleic acid purification.

Tip Consumption Calculator

The dependency on pipette and liquid handler tips is costly on the wallet as well as the environment. Use the Tip Consumption Calculator to see how many tips you are using in a year and how long it will take you to recover the cost of a C.WASH using only pipette tip savings!

C.WASH™ washing efficiency improves the reproducibility of results, drives down costs, reduces timelines and maximizes overall assay efficiency.

Features designed to improve efficiency and speed up your workflow

Fast and automated
Fully automated and stand alone operation, 1 wash cycle in 96- or 384-well plate <1 min​

Cell-based assays

C.WASH automates all the washing and dispensing steps in a typical screening workflow, making it an essential device for drug discovery or gene editing in HTS environments. 


ELISAs are very sensitive immunoassays, therefore cross contamination and/or pipetting inaccuracies may result in high coefficient of variation (CV). The accurate non-contact dispensing limits both cross-contamination and therefore reduce CV. Moreover, the lower residual volume after washing enables a better washing efficiency and reduces the number of washes.

DNA purification

Using beads to clean up DNA has become the gold standard for NGS library preparation. Although it is a quick and easy method, the reduced cost for high throughput sequencing and the popularity of single cell sequencing have considerably increased the sample to be processed. The C.WASH can automate this workflow in both 96 and 384 microplates, thank to our compatible Magnetic plate carriers.

Highly reproducible washing efficiency

Featuring a residual volume of <0.1 uL/well, C.WASH dramatically reduces the number of wash cycles required and results in faster, more reproducible assays.

Highly Efficient Washing of Microwell Plates Using Centrifugal Forces

C.WASH software was designed with ease of use in mind, its automation saves valuable time.

With an intuitive design and quick access tabs, the C.WASH ensures that you are as efficient as possible. This innovative method of plate washing improves the reproducibility of results, drives down costs, reduces timelines and maximizes overall assay efficiency.

Intuitive – User friendly software

This is the key feature of our system and provides a unique competitive advantage in the marketplace. The intuitive nature of the software allows for guidance through each step of your protocol.

Creation of customized programs

The feature most appreciated by the user allows them to choose a variety of options, including pause time, shaking and decanting and centrifugation time.

Automation friendly software architecture

The well-documented communication via the SiLA2 interface ( Standardization in Laboratory Automation), allows integration with Automation Programming Interface and is compatible with third-party control software.

The C.WASH is SiLA2 compliant, which facilitate its integration in HTS facilities.

Waste system in C.WASH™

Liquid inputs
Auto switching (internal) for up to 4 liquid input channels, with auto priming function.

Waste system
The waste is discarded through an active pump, which prevents the clogging of the internal tubing. It also reduces the instrument footprint, as it allows the integration in any lab configuration.
