Échantillons
Des spécimens sont disponibles pour une grande variété de procédures de test organiques et inorganiques. Les échantillons organiques peuvent être utilisés pour la dissection ou l’étude de spécimens entiers, vivants ou conservés, avec des exemples pratiques en biologie cellulaire ou dans l’analyse de la structure interne d’organes et de systèmes multicellulaires complexes. Les spécimens de roche permettent l’étude des textures, des tailles de grains et d’autres caractéristiques influencées par la pression, la température et d’autres forces naturelles, offrant un aperçu de l’histoire géologique de la Terre.
