The equipment you possible mean is IAsys that is manufactured by
Affinity sensors. The system comes from UK. It's not that new, I think
that their biosensor has lifehistory of at least three or four years.
The main difference between these two device is that when Biacore has
flowthrough system the Iasys is based on cuvette construction. You can
find a short "review" about the subject from newspaper Genetic
engineering news: november 15, 1996.

Cheers, Olli
