Bringing Correlative light and electron microscopy forward with the CryoCapsule®
High pressure freezing is the most advanced technology when it comes to vitrify a hydrated biological specimen while preserving the ultrastructure. Developed in the 80's , the technology evolved progressively to become accessible to a larger community. Still, the sample preparation prior to HPF remains tedious and often comes to advance expertise depending on the specimen .
The CryoCapsule® is a new tool in the field of High Pressure Freezing (HPF) and correlative light and electron microscopy (CLEM). Comparable to a small petri dish, it is composed of a landmarked sapphire disc and a gold spacer ring (50µm thick) maintained together by a plastic ring .

The specimens are encapsulated between the support sapphire disc (carbon landmarked) and a covering sapphire disc.
The CryoCapsule® is loaded into a specific adaptor (HPM010, HPM100, HPF compact 02). Live cell imaging is done directly on the specimen in the CryoCapsule® prior to HPF.

Post-HPF, the specimen is processed for freeze substitution  and room temperature sectioning.
CryoCapCell has developed a set of tools to manipulate the CryoCapsule®  in most scientific environments.
