Product Image-765-0089

Maltese cross tube

Catalog Number: (765-0089)
Supplier: 3B Scientific
Description: Evacuated glass flask containing i.a. electron gun with directly heated tungsten wire cathode and a cylindrical anode. The electron gun emits a divergent electron beam, aimed at an Maltese cross of aluminum placed in the middle of the tube. The cross can be connected electrically. At the same time, light from the filament is also directed towards the cross, so that a comparison can be made between the shadows of different types that appear on the luminescent surface at the far end of the tube.

Product Image-BE-202

Experimentation kits, bacterial gram staining

Catalog Number: (BE-202)
Supplier: G-Biosciences
Description: The Gram staining method was first described in 1844 by the Danish bacteriologist Hans Christian Gram, after whom the test was named. The Gram staining test for bacteria is one of the most important tests in microbiology and is often one of the first tests performed in the identification of bacteria. The Gram staining method utilises the properties of bacterial cell walls and the stain crystal violet. Gram-positive microorganisms have a higher peptidoglycan and lower lipid content than Gram-negative bacteria in their cell walls and this makes them capable of retaining the Gram stain. This kit is supplied with two strains of bacteria and all the necessary components to carry out the Gram staining.

Electron deflection tube D

Catalog Number: (761-0136)
Supplier: 3B Scientific
Description: 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.
