".2mL PCR tubes"

Guinea and feather tube apparatus with 6 induction coils connected in series.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.

Demonstrates static electricity's attractive and repulsive forces using a pendulum electroscope.​

Demonstrate the Lorentz force and calculate the charge/mass ratio of an electron.

Investigate the deflection of electrons.

The high-frequency coil can be used to test vacuum equipment for leakage or excite electrical tubes for demonstrations.

Universally applicable, floating, high-voltage power supply with built-in, high voltage resistant transformer to supply the heater voltage for electron tubes. Continuously adjustable high voltage, safe to touch, with passive current limitation and analog voltage display. Unit poles can be connected to protected earth, but it is not center tapped.

Helmholtz coils are used to produce a homogeneous magnetic field. Experiments on induction and electron deflection can be performed with the Rotary Frame with Flat Coil and the Fine Beam Tube. The coils can be used in parallel or in series and feature a spring clip on the cross bar to mount a Hall Sensor for measurements of the magnetic field. The maximum field strength generated by the coils (~ 4 mT) is approximately 750 times weaker than that produced by an MRI machine (~ 3T), which are known to be safe for use by people with medical implants such as pacemakers.

The Air Core Solenoid is perfect for induced magnetic field studies.

Standard resistance rheostat.

Eddy current for demonstrating Lenz's law.

The Air-Cooled Laboratory Rheostat is the classic lab solution for controlling voltages and currents.

The Lenz's Law Kit investigates how much force an induced magnetic field can create.

The Eddy Current Experiment demonstrates Lenz's Law.

Glows with Characteristic Brilliance!

Small electrolysis apparatus with beaker included.
