Experimentation kits, bacterial culture and growth study

Experimentation kits, bacterial culture and growth study

Supplier: G-Biosciences

This kit teaches aseptic handling techniques and cultivation of bacteria in liquid culture media and on solid phase agar plates. This kit is designed to educate students about the various stages of the bacterial growth cycle, i.e. lag, log or exponential, stationary and decline or death phases. The kit also teaches the importance of growing bacteria on solid phase agar plates to isolate single colonies of bacteria. This lab activity involves preparation of culture medium and solid agar plates.

Experimentation kits, bacterial gram staining

Experimentation kits, bacterial gram staining

Supplier: G-Biosciences

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.

Experimentation kits, antibiotic sensitivity and bacteria screening

Experimentation kits, antibiotic sensitivity and bacteria screening

Supplier: G-Biosciences

Antibiotics play a crucial role in the manipulation, screening and killing of bacteria in a range of biotechnology processes. This kit specifically teaches the basic principles of antibiotics, bacterial resistance and susceptibility. Students learn and understand the use of antibiotic resistance in screening for infectious diseases. Utilising a bacterial strain, students learn the effects of different antibiotics and visualise bacterial sensitivity and resistance to the supplied antibiotics. This method involves the use of filter paper discs impregnated with a specified concentration of antibiotics on the surface of an agar plate containing microbial cells. This kit will enable students to analyse the inhibitory effects of different antibiotics on selected bacterial cells and then determine which antibiotic is the most suitable to treat a bacterial infection.

Helmholtz coils

Helmholtz coils

Supplier: ELWE LEHRGERAETEBAU KLINGENTHA

Used e.g. to form homogeneous magnetic fields. Two identical coils placed in parallel by means of three fastening devices. The coils can be connected in series or in parallel. To determine e/m, the wire beam tube is placed between the Helmholtz coils in such a way that the visible beam is perpendicular to the homogeneous magnetic field. The generated magnetic field can be measured with a magnetic field meter with hall elements. Specifications.

Motor, 12 V DC, with iron-free rotor

Supplier: ELWE LEHRGERAETEBAU KLINGENTHA

Motor with rotor that lacks iron and thereby has a very low moment of inertia, which in turn enables fast start and stop or change of direction of rotation. The time from start to maximum speed (3000 rpm) is only 11 ms. Can be used for experiments with mechanical oscillations. The motor is most conveniently operated with a function generator.

Planck's constant, experimental equipment

Planck's constant, experimental equipment

Supplier: OSRAM

Equipment for demonstrating photoelectric power and determining Planck's constant. A photocell is equipped with filters that only transmit light of a certain wavelength. The photocell is illuminated with light from a Hg lamp. The potassium cathode then emits electrons that pass over to the unlit anode. Over time, a voltage arises that prevents new electrons from reaching the anode. The resulting voltage is measured with a measuring amplifier and a voltmeter. The measurement is repeated with filters for different wavelengths. Photocell and Hg lamp are equipped with magnets at the bottom for stable installation on the mounting plate. List of equipment:

The charge of the electron, acc. busch

Supplier: ELWE LEHRGERAETEBAU KLINGENTHA

The exercise oscilloscope is placed at the Helmholtz coils so that its main axis coincides with the axis of the coils. A sawtooth-shaped voltage is applied to the deflection plates of the oscilloscope so that a smooth horizontal line appears on the screen. Let direct current pass through the coils at a preset anode voltage and adjust the intensity of the current so that the line is focused at one point. The specific charge e/m of the electron can be calculated from the measured values ​​of the anode voltage and the current through the coil.

Franck-hertz tries with

Franck-hertz tries with

Supplier: ELWE LEHRGERAETEBAU KLINGENTHA

Franck-Hertz's experiment is one of the best ways to show the quantum properties of atoms. The experiment verifies the excitation energy of the Hg atoms through collisions with free electrons. Franck-Hertz tubes consist of an oxide cathode, gallery anode and a collection electrode. The evacuated tube contains a drop of Hg. Before starting the measurements, the pipe must be heated to 200 °C, partly to increase the pressure of the Hg steam and partly to obtain a sufficient probability of collision. When the temperature in the tube has become constant, the cathode is heated and a direct voltage which can be varied in the range 0 to 50 V is connected between the cathode and the anode. When the counter voltage is set to about -1,5 V and the anode voltage increases slowly from 0 V, the electrons will soon reach speeds in the acceleration range of the tube so that an increasing part of the primary current reaches the collector electrode. As the velocity of the electron flux approaches the lowest excitation level of the Hg atoms (4,9 eV), the electrons of the Hg atoms are capable of leaving the atoms and thus losing some of their velocity. The collector current drops to a minimum value. The Hg atom then emits its 253,7 nm ultraviolet line and then returns to its normal energy level. As the acceleration voltage increases further, the current reaching the collector electrode will increase again. This process is repeated periodically many times.
