Break the rules.

Waiting days to weeks for core lab data on what your cells have consumed? Say NO to the core and regain that time.

The Rebel® puts control in your hands. Run spent media analysis at-line, anytime. Get real-time data on over 30 components in your cell growth media in minutes.

Skip the status quo.

YOU run the Rebel alongside your bioreactors. The core lab doesn’t have to lift a finger. In 7 minutes you’ll get a quantitative list of amino acids, dipeptides, water soluble vitamins and amines. Combine that with your other standard biochemical markers and make decisions in a snap. You’ll shave process development cycles by weeks, if not more.

You say when and where.

The Rebel is simple. Pull a bioreactor sample, spin it down, and dilute. Load it in and hit start. Run samples solo or in 96-well plates if you’re a real go-getter.

There’s no futzing around with settings or analysis either. The Rebel already knows which knobs to turn, and data analysis is validated ahead of time. At the end of the run, you’ll have a full report on analytes detected and their concentration. Reports are uploaded to network drives automatically, so you can check results remotely too.

Unbox and go.

Rebel consumable kits make it easy.  Reagents are premixed, and each kit comes with electrolyte, diluent, standards, sample plates, and a chip. That’s everything you need to run 200 samples. All in one box.

Popular FAQs:

  • How do I load samples and queue up a run on the Rebel?

    The Rebel accepts both septa capped vials and 96-well plates. We provide two plates with each consumable kit. The Rebel’s autosampler is cooled to 5 °C, and there are plate covers included in the kits to prevent evaporation. Once your samples are loaded, you can manually input your sample information using the Rebel’s intuitive user interface and touchscreen or import a CSV template file that you have already prefilled. The template expedites the process if you are loading a full plate of samples, and we provide the template to you during installation.

  • What data formats does the Rebel export, and how are the files saved?

    The Rebel saves processed reports in either CSV or PDF file formats. When configured for network storage, the files are saved in real time. No permanent storage of data files or reports is ensured on the Rebel if saved on the internal storage system. It is expected that your company’s corporate IT policies can be employed for the resulting files deposited on network shares for long term retention, fraud prevention and adulteration.
