What is it for? Use it if you want someone to take care of the preparation of your blinking buffer or STED-derivative buffer, for MINFLUX-like techniques namely. Use it as well if you want to prepare samples on Monday, and image on Tuesday. Or even Friday!
Use it also if you want to prepare your samples in your lab, and image in your core facility

We prepare your buffer on demand for you. We deliver it when you need. Your buffer is ready-to-use: pour it, seal it, image it!

 Prices from 150€. See our offers.


High stability over time

Samples are stable over several weeks

Wide pH range

Wide pH range (5-8) where most biological phenomena occur, contrary to enzyme-based buffers that require a pH of 8 for efficient blinking.


Highly efficient dark state transition


Compatible with red and far red dSTORM blinking fluorophores (AF647, AF568, DL550, DL650)

Ready to use

Can be used directly from the vial

2 months performance

Optimal performance for 2 months after production


HILO, TIRF pattern.

Made on-demand

Fresh batches are produced at will, every week, for each order you make. They are delivered on the spot anywhere.

Everspark and us

"We designed the Everspark buffer to facilitate sample preparation for dSTORM super-resolution imaging. Indeed, an oxygen-free buffer containing a thiol reducer is central to promote fluorophore blinking and thus single molecule detection, required for dSTORM imaging. With classical buffers, such as the Glox buffer, fluorophore blinking lifetime is limited to a few hours. With Everspark buffer, it is now possible to increase sample lifetime to several weeks. We demonstrated that a calibrated sample mounted once with the Everspark buffer can be submitted to several rounds of dSTORM imaging to acquire and reconstruct a structure reproducible in coverage and precision, over a period of two months."

"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".
