".2mL PCR tubes"

Hertz electron tube for quantitative investigations of Inelastic collisions of electrons with inert gas atoms.

Investigate the relationship between the speed of a fluid and its pressure

Demonstrate the free-fall motion of objects in atmospheric pressure and vacuum conditions.

Students measure pressure with a precision manometer.

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.

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.

High quality and reliable.
