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.

This high-quality functional knee joint model of a naturally-sized right knee joint with ligaments shows the anatomy and possible physiological movements (e.g. abductions, anteversion, retroversion, internal and external rotation) in exceptional detail. This knee joint model also clearly defines the ACL and PCL. The colour of the natural-cast bones of the knee joint is extremely realistic. The cartilage on the knee joint surfaces is marked blue.

The KNM-ER 406, Omo L. 7a-125 skull model is the finest casting produced from scientifically made copies of specimens. This unique KNM-ER 406, Omo L. 7a-125 replica is supplemented by having it displayed on a pedestal that contains a relief map of the geographical area where the skull specimen was found. This KNM-ER 406, Omo L. 7a-125 skull model is a high-quality casting of a reconstruction of the Kalvarium skull (KMN-ER 406) with a partial mandible (Omo L. 7a-125). The Kalvarium skull is approximately 1,7 million years old and was discovered at Lake Rudolph (now called Lake Turkana) in 1970. The partial mandible comes from a different dig but is clearly from the same species. The classification of the species that this skull comes from has not yet been indisputably clarified. Discussions continue as to whether the anatomical features of this skull specimen points to classification as an Australopithecus boisei or a Paranthropus boisei. Example of a pre-human hominid. Discovered at: Lake Turkana, formerly Lake Rudolph Discovery: 1970 Age: about 1,7 million years This KNM-ER 406, Omo L. 7a-125 skull replica is a great tool for teaching and learning the anatomy of early huminid species.
