These packs of ultra-thin aluminum foil pieces are sold to replace worn out foil in many electroscopes or to create your own at home. Available in packs of 12 pieces or cases of 120 pieces.

Our Electroscope Rod Assembly is designed to be a replacement for our Flask-Type Electroscope ( #4-50150 ), though it can be used to create an electroscope of your own. At one end of the rod assembly there is a clip for holding electroscope foil.

Electroscopes are used to detect and roughly measure the electric charge on an item. This electroscope has a round case, a free-spinning pointer, and a gauge.

Electroscopes are used to detect and roughly measure the electric charge on an item. This aluminum-leaf electroscope has a metal case with a round viewing window.

An economical electroscope consisting of aluminum leaves mounted on a metal rod (item #4-50160) held by a rubber stopper in a 250ml flask. Instructions included.

The unit is bigger than standard electroscopes for easy viewing. The leaf is larger and the wide radius of swing provides a visual and sensitive demonstration.

Demonstrate key electrostatics concepts with this kit. Contains everything necessary to construct two flask form elctroscopes.

With the Electrostatic Charge Kit, your students will have fun experimenting with static electricity. Instructions included.

Contains Hollow Friction Rod, Solid Friction Rod, 1/2 Ground Friction Rod, Ebonite Rod, Wool Pad, Silk Pad, Faux Fur Pad, 3-Balloons and 10 feet of String. Instructions included.

The Electrostatics Kit is a collection of materials designed for students to investigate the creation of charges through friction between various rods and fabrics. Contents include: Hollow Glass Friction Rod (1) Glass Friction Rod, Half Ground (1)

Recommended for grades 3 to 8, this set is ideal for introducing students to the concepts of changing force by levers and pulleys, and the notion of mechanical advantage. The manual describes experiments with the three types of levers, single and

Lab activity that teaches the use of lock-key matching properties of antigen-antibody for detection as well as quantification of antibody or antigenic proteins in complex samples. This method is widely known as Enzyme Linked Immunosorbent Assay, or
