The VitroJetTM is designed to take the frustration and waste out of CryoEM sample preparation by allowing researchers to optimize the settings of ice quality, ice thickness and sample deposition before placement in the microscope. Providing a more efficient way for optimizing sample conditions for a higher return from data collection, and allowing researchers to focus on the true research.

CryoEM Sample Preparation

Did you know that even after optimizing sample conditions only about one in four grids prepared for CryoEM are suitable for data collection?

This means that even with well understood samples, the vast majority of grids prepared have issues with layer thickness or ice quality which wastes expensive microscope time, samples, and research opportunities. However, even before sample conditions have been optimized, equipment issues can make finding the best protein concentrations, buffering conditions, and ice thickness a challenge. Here, researchers may have issues spotting the difference between bad sample conditions and bad sample preparation.

The VitroJetTM is designed to produce grids with better than 90% acceptable ice quality for data collection.
