Why Choose Aura+?

When you need the flexibility to conduct particle characterization analyses on different types of biologics, including protein and antibody therapeutics, cell therapies, and gene therapies, the Aura+ has got you covered.

Analyze small volumes. The minimum sample volume is just 5 µL, enabling particle characterization earlier in the development timeline when sample volumes can be limited.

Gain insight quickly. With a 96-well membrane plate and the ability to analyze one sample every minute, the Aura+ takes you from labeled samples to data in as little as 90 minutes.

Get Fast, Definitive Particle Identification With Three Fluorescence Channels

Aura+ comes with three fluorescence channels so you can get the same information from one experiment that would otherwise take three different studies.

In addition, Aura+ definitively identifies different types of particles within the same sample for more reliable decision-making:

  • Three FMM channels for three different species of organic particles
  • SIMI channel for extrinsics and inorganic particles

See Clearer With High Magnification

With the high magnification capabilities of the Aura+, you can see more morphological detail of unlabeled particles, enabling decisive discrimination between your lead and undesirable particles.

Quickly differentiate and enumerate cells versus Dynabeads™️, quantify polysorbate degradation, and more.
