Blast through process development.

Optimize media in real time with the Rebel.

At-line, anytime.

Bring the horsepower of the core to your process development lab. Run fresh or spent media samples and get answers in real time. Bypass complicated instrumentation like HPLC or LC-MS. Getting answers is simple with the Rebel™, and you’re in charge of where and when.

Do more. Waste less.

Using a drop of sample, get readings on up to 32 analytes in the same time it currently takes for a handful.

Defy your workflow

Pull a sample

1. Pull a sample

Pull a sample from your bioreactor, shake flask or well plate. The Rebel only needs 10µL.

Spin and dilute

2. Spin and dilute

Spin out your cells and dilute. That’s as complicated as it gets.

Load your samples

3. Load your samples

Load your samples, reagents and calibrants.

Generate results

4. Generate results

Hit start, get results. Results can quickly be reviewed in a simple report.


With the Rebel, data is delivered processed and polished. The onboard algorithms worry about calibration and standards so there is no heavy lifting for you. As runs are completed, you can print out pdfs or import csv files to an electronic lab notebook. Whatever the workflow, the answers are in a friendly non-proprietary format allowing you to focus on your next experiments, not data wrangling.
