"tube coolers"

Ideal for Index of Refraction and Total Internal Reflection Experiments

This newly designed rheostat features a protective cover.

Students Investigate Alternative Energy Forms

Ideal for demonstrating that vapor pressure increases when temperature increases.

Both versions of these economy tuning fork sets come with a mallet designed for one hard and one soft end for use with all frequencies of forks.

Effective Method of Showing Normally Invisible Currents

Scientific tuning forks are designed for acoustic research, sound wave analysis, and calibration standards.

Enough materials for a complete class to perform all of the electrostatics experiments included in this set.

Alloy tuning fork economy stamped.

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.

Glows with Characteristic Brilliance!

The Speed of a Bubble Set connects the mathematical concept of slope to the physical science concept of velocity.

The 3D Magnet Viewer displays clear views of magnetic fields.

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.

This Ballistics Cart demonstrates the independence of vertical and horizontal motions.

With the Resonance Apparatus, students investigate the effect of frequency on wavelength.
