Item no.: P2541602 Principle Laue diagrams are produced when monocrystals are irradiated with polychromatic X-rays. This method is primarily used for the determination of crystal symmetries and the orientation of crystals. When a LiF monocrystal is irradiated with polychromatic X-rays, a characteristic diffraction pattern results. This pattern is photographed with the digital X-ray sensor XRIS.
Item no.: P2530101 Principle The resistivity and Hall voltage of a rectangular germanium sample are measured as a function of temperature and magnetic field. The band spacing, the specific conductivity, the type of charge carrier and the mobility of the charge carriers are determined from the measurements. Tasks The Hall voltage is measured at room
Item no.: P5942100 Principle The fundamental principles concerning the phenomenon of nuclear magnetic resonance (NMR) are demonstrated. Experiments are executed with a MRT training device giving the opportunity to investigate some small probes in the sample chamber. Device control is done with the provided software. Investigations comprise the tuning of the system frequency to the Larmor frequency,
Item no.: P2511005 Principle The “Zeeman effect” is the splitting up of the spectral lines of atoms within a magnetic field. The simplest is the splitting up of one spectral line into three components called the “normal Zeeman effect”. In this experiment the normal Zeeman effect as well as the anomalous Zeeman effect are studied
The Lascells digital ammeter is housed in robust ABS and PVC cases. It features ~40 minute ‘auto off’ circuitry to conserve battery life and an LED indicator prompting battery change when necessary. Technical Specifications: Ammeter: RANGE: 0 to ± 10A d.c. RESOLUTION: 0.01A ACCURACY: ± 2% INPUT IMPEDANCE: 0.01Ω Approx. POWER: 9V PP3 Battery
Item no.: XWV590012 New and updated for 2015. This compact unit provides an elegant method of demonstrating the wave phenomena of reflection, diffraction, refraction and interference with none of the setting-up problems usually associated with ripple tanks. The concept has been further developed to offer new features and simplicity in this MkIII design. The unit is
Item no.:XAR260010 A new and improved spark detector gives a memorable and dramatic demonstration of the ionising properties of alpha particles. Alpha particles have short range but are very effective at ionizing air. In this apparatus a number of fine wires are supported above a metal plate to form two electrodes separated by a small
Item no.: XAR040010 The Lascells cloud chamber is the perfect alternative to existing unreliable and time consuming dry ice variants. The chamber is self-contained and thermoelectrically cooled. The chamber requires no dry ice; the only setup necessary is the addition of isopropyl alcohol and connection to a mains socket. The chamber contains an integrated power supply
Item no.: YAS490010 The gravity well is an exciting piece of apparatus which allows students to visualise the attraction of massive objects due to gravity. Consisting of a flexible sheet and collapsible frame, the gravity well is supplied with all you need to bring the study of gravity to life. • Coalescence of stars • Orbiting
