Innovative Centrifugal Plate Washing Meets Unrivaled Washing Efficiency

C.WASH PLUS redefines plate washing with its centrifugal approach – efficient, fast, and reliable. Achieve over 99.99% washing efficiency (after 2 wash cycles) with less than 0.1 µL residual volume in each well, all in under a minute per cycle. This means fewer wash cycles and reduced reagent use – saving you time and money.

Dispenser: Gentle, Efficient, Precise And Dedicated

C.WASH PLUS isn’t just an upgrade; it’s a revolution in lab tech. Now equipped with a precision dispenser, it’s the epitome of gentle yet efficient lab work. Picture this: dispensing with such precision and accuracy that your cells feel like they’re at a spa, not a lab. Low to zero dead volume? Check. Dispensing down to the last drop with higher accuracy? Double-check. And flexibility? It’s like a Swiss Army knife for your assays, with up to 12 liquid inputs to automate complex procedures like ELISA or cell staining. The real clincher? It’s cell friendly. We’re talking about precision plate positioning and adjustable pressure that keep cells snug in their wells across 96, 384, and 1536 well plates. So, cells stay put, and you stay ahead. C.WASH PLUS isn’t just doing the job; it’s setting new standards.

Plus, with automation and without needles to clog, it offers increased reliability and more hands-off operation. C.WASH PLUS isn’t just efficient; it’s a game-changer in automated workflows. 

Plus-Sized Data

C.WASH PLUS changes the game in compound profiling. Less background noise, sharper signal-to-noise ratios, and rock-solid % CV – that’s reliability you can count on. Manual washing? It’s hit or miss. But C.WASH PLUS delivers even, consistent results every time. Think smaller CVs, improved Z-factors – the kind of data that speaks for itself. It’s not just an upgrade; it’s a whole new standard in the lab.

Automate Entire Assays

12 liquid inputs and the new precision dispenser make the C.WASH PLUS the ideal system for automating entire assays such as ELISA or cell staining & washing procedures.

Clog-Free Waste Removal

Keep your C.WASH PLUS automated microplate washer running smoothly with little maintenance thanks to the active pump waste system which prevents clogging in the internal tubing. This benchtop instrument with a clog-free design makes integration into any lab configuration easy.

Seamless Automation and Integration

C.WASH PLUS is SiLA2 compliant, which means it can be seamlessly integrated into automated platforms. Its compatibility and ease of integration simplify the incorporation of the instrument into your existing systems.

Software: Programmable Plus Versatile

The C.WASH PLUS software was designed with ease of use in mind, and its automation saves valuable time. With an intuitive design and quick access tabs, the C.WASH PLUS ensures that you are as efficient as possible. The well-documented communication via SiLA2 interface allows integration with APIs and is compatible with third-party control software.


Accelerate your research

Assay Automation

To fully automate common cell-based assay protocols, several buffers and staining solutions need to be dispensed. Some of these reagent are expensive and require a precise dispensing with minimal dead-volumes. Additionally, in order to automate the entire ELISA protocol, additional reagents need to be dispensed: a coating buffer, a blocking buffer, and antibody solutions. Some of these reagent are also expensive and require a precise dispensing with minimal dead-volumes. Assay automation with minimal waste is now made possible with the C.WASH PLUS.

Immunoassays (e.g. ELISA plate washing and multiplexed protein assays such as MSD)

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 reduces CV. Moreover, the lower residual volume after washing enables better washing efficiency and reduces the number of washes required.

Cell Washing – Adherent and Suspension Cells

Use the C.WASH PLUS as a simple and reproducible method to wash suspension cells. Following centrifugation of the plate to pellet cells, the liquid supernatant is then evacuating using the C.WASH PLUS, resulting in washes with consistent low residual volume and with maximal cell retention as compared to manual workflow.

Plate Coating

Coating wells with proteins or peptides maximizes cell adhesion in your microplates. Streamline the coating process in your laboratory using the C.WASH PLUS. Dispense the coating solution, choose your incubation time and wash and dry the plates for optimum and reproducible coating of your plates.
