GraVitri Plunge Cooler Series
The GraVitri™ Plunge Cooler Series is a high-performance, modular platform engineered for the consistent vitrification of cryo-EM samples. Utilising a precision gravity-driven mechanism, the system achieves terminal plunge speeds of 2 m/s, ensuring optimal ice quality for Single Particle Analysis (SPA), Cryo-ET, and Micro-ED.
- Validated Performance: Developed in collaboration with Dr. Chris Russo (MRC Cambridge).
- Lab Independence: An affordable, benchtop solution that eliminates shared facility wait-times and scheduling bottlenecks.
- High Velocity: Guaranteed 2 m/s plunge speed paired with a vibration-dampened stopping mechanism to protect delicate grids.
- No Power Required: The Basic and Standard models are purely mechanical, offering total portability and zero electrical maintenance.
