La cryo-microscopie est une technique utilisée pour l’observation des molécules cellulaires et biologiques à des températures cryogéniques. Le CRYO ARMTM 300 II intègre les dernières technologies JEOL pour la cryo-microscopie : Cold FEG, filtre en énergie Omega, système d’échange automatique des échantillons à température cryogénique…
Collection ultra rapide de données
Le CRYO ARM ™ 300 II permet une acquisition de données à très grande vitesse en combinant le déplacement du faisceau avec un mouvement précis de la platine goniométrique. De plus, l'excellent contrôle du faisceau de ce système minimise l’aberration de coma.
Par conséquent, le vitesse d’acquisition peut être augmentée de façon importante (> 2200 films / heures) sans dégrader la qualité d'image.
Mode sans Frange de Fresnel
En plus de l’illumination conventionnelle, le CRYO ARM ™ 300 II dispose d'une illumination unique en « mode Koehler ». Ce mode permet de s’affranchir des franges d'interférence et élimine les dommages causés par le faisceau d'électrons aux zones non utilisées pour l'imagerie. Il vous permet d'obtenir plus d'images.
