Kits d'expérimentation, coloration de Gram des bactéries
Supplier: G-Biosciences
Décrite pour la première fois en 1844 par le bactériologiste danois Hans Christian Gram, la méthode de coloration de Gram porte le nom de son inventeur. La coloration des bactéries de Gram constitue l'un des principaux tests en microbiologie et souvent l'un des premiers tests pratiqués dans l'identification des bactéries. La méthode de coloration de Gram fait appel aux propriétés des parois des cellules bactériennes et au colorant cristal violet. Les parois des microorganismes à Gram positif ont une plus grande quantité de peptidoglycanes et une teneur lipidique inférieure aux bactéries à Gram négatif, ce qui leur permet de retenir le colorant de Gram. Ce kit est fourni avec deux souches de bactéries et tous les composants nécessaires pour réaliser la coloration de Gram.

Kit d'expérimentation, sensibilité aux antibiotiques et dépistage de bactéries
Supplier: G-Biosciences
Les antibiotiques jouent un rôle essentiel dans la manipulation, le dépistage et la destruction de bactéries d'une gamme de processus de biotechnologie. Ce kit enseigne tout particulièrement les principes de base des antibiotiques, la résistance et la susceptibilité bactérienne. Les étudiants apprennent et assimilent l'utilisation de l'antibiorésistance dans le dépistage des maladies infectieuses. À l'aide d'une souche bactérienne, les étudiants apprennent les effets des différents antibiotiques et visualisent la sensibilité et la résistance bactériennes aux antibiotiques fournis. Cette méthode implique l'utilisation de disques de papier filtre imprégnés avec une concentration spécifiée d'antibiotiques à la surface d'une plaque de gélose contenant des cellules microbiennes. Ce kit va permettre aux étudiants d'analyser les effets inhibiteurs de différents antibiotiques sur les cellules bactériennes sélectionnées, puis de déterminer l'antibiotique le plus adapté pour traiter une infection bactérienne.

Electron deflection tube D
Supplier: 3B Scientific
Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using an optional Helmholtz coil pair D. By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge e/m and the velocity of the electrons.
