"Tubes"

Employs Guericke’s Method for Demonstrating the Force of Atmospheric Pressure.

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

This vacuum plate and pad are the perfect tools for vacuum experiments.

Ideal for demonstrating that vapor pressure increases when temperature increases.

Effective Method of Showing Normally Invisible Currents

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.

High quality linear expansion apparatus to study thermal expansion.

This is a classic example of thermodynamics in action.
