Reclaim your bench

At 22 cm wide, we designed Arista to be small. This means short tubing runs and less dead volume. Powerful Arista leaves you room to operate.

Browsers are best

Arista Chromatography system runs in a Chrome Browser

Run on Browser

Arista runs on Chrome. Use a tablet, Windows, Mac or Linux. If it runs Chrome, it runs Arista.

Arista’s software runs on its built in server. Updates take only a few clicks. No drivers, no compatibility issues, no problems.

Arista continually saves data. In the event of a power failure, find your data after rebooting.

The internal solid state disk (SSD) holds over 10 000 hours of run data.

Flexible Fluid Handling

Arista is built to work with selected third party fraction collectors.

Advanced Materials & Design

Chemically resistant carbon fiber protects Arista from the natural hazards of protein purification.

And it looks awesome.

Compatible with your columns

Arista works well with all columns, including the ones in your lab.
