Overview

No more rushing your imaging. Prepare your slide, and image quietly whenever you want, even 3 to 4 weeks later.
Image with red, far red and green dyes (eg. AF488). Use different colors either at the same time or one after the other.

Feedback from the Test Program
Everspark works with thick samples of 100µ (peripheral blinking).
Everspark does not work 100% efficiently with organs and tissues because there is most of the times a bit of remaining oxygen.

Story
Esther Graudens
New projects at Idylle
"When I was working on long manipulations, I dreamed of being able to stop at certain crucial stages. Everspark is the ideal answer to the problem of many researchers who prepare their samples in a hurry simply because they need to image them right away. The Everspark buffer eliminates this tension: they take the time to image whenever they want, with complete peace of mind. They can also make acquisitions over several days. This will really change the way people prepare their experimentations, and that's exactly what I like about my job!
In terms of production, I am very proud of the way we have managed to set up a just-in-time production process in our labs in record time. And when researchers ask us to introduce variants, our production teams are able to build and produce very quickly their customized buffer to test it".
