".2mL PCR tubes"

Students measure pressure with a precision manometer.

Accurately determine the melting temperature of a solid.

Prefilled And Etched For Proper Breakage.

"Genie in the tube."

The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

Used to investigate wavelength in air.

Demonstrate the classic free fall experiment in a vacuum.

Explore beautiful 3-D patterns created by a magnetic field mess free.

The Student Coin and Feather Tube shows the two items in a vacuum, falling at the same rate.

Highly evacuated electron tube with focusing electron gun and fluorescent screen 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 the Helmholtz coil pair (not included). 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.

High quality and reliable.

Study Wavelengths and Energy All With One Device

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 wavelength of sound on an open end tube.
