ELECTROSCOPE CASE GOLD FOIL
Electroscope Case
Gold Foil Type Larger size and high durability make this perfect for student use! Gold Foil Electroscope is a classic in physics demonstrations and science classes. This unit is bigger and easier for the student to view. The leaf is a little larger and the wide radius of swing provides a visual and sensitive demonstration. The unit also features a built-in scale which helps to determine the amount of charge generated. The metal case is strong and stable to resist damage. (8" x 3-1/2" x 9-1/2"; 2.25lbs). |

VAN DE GRAFF GENERATOR
Van de Graaff Generator with accessories
An economical, all-purpose electrostatic generator! Introducing
a new Van de Graaff Generator that is both high-quality,
variable speed and affordably priced. Everything is visible to
the student with this remarkable unit. Complete with many
accessories such as
- a discharge wand
- extra belt
- pithball &
stand
- discharge needles
- comb
- spinning wheel
- neon tester
- synthetic hair with plug
- aluminum cup and static chamber
(8" x 11" x 24"; 10 lbs). |
|
Flask & Assembly
Perfect for individual use! A practical and economical electroscope consisting of aluminum leaves mounted on a metal rod held by a rubber stopper in a 250ml flask. This assembly can be supplied with either of the two types of Rod Assemblies listed below. Instructions provided. (3-1/2" x 3-1/2" x 6-1/2"; .5Ib). |
|
METAL CASE ELECTROSCOPE
Electroscope
Metal Case This electroscope box is made of anodized aluminum with glass windows in both the front and back of the box. The glass plates prevent an erratic motion of the leaves by shielding them; thereby allowing the leaves to react only to charges that are intentionally brought near them. The plates are easily removable, allowing for introduction of ionizing material. Instructions provided. (5-1/8" x 3-5/8"; .5Ib). |
|
ELECTROSCOPE WITH PITH BALLS
Electroscope with Electrostatic Balls
A sturdy demonstration of electrostatic activity! Electrostatic balls are suspended on an aluminum hook attached to an acrylic base. When a static change is brought near the balls, they react to the electrical charge. Instructions provided. (9" x 4-1/2"; .124lb). |
|
ELECTROSCOPE ENCLOSED
Electroscope
Enclosed Unit The perfect way to explore electrostatic principles without outside interference! Great for small children; the unit contains no glass or easily broken parts. A brass ball sits atop a plastic cap, from which very fine copper wires attached to electrostatic balls are suspended. The entire unit is sealed in a clear plastic cylinder that shields air currents. Instructions are provided. (3-7/8"H x 3" diameter; .175lb). |
|
FARADAY CAGE KIT
Faraday's Cage Kit
Useful in the study of potential build-up inside a conductor cage! Two of the possible experiments are the lightening rod effect and surface charge distribution. The unit measures 270mm x 120mm. Instructions included. (5" x 5" x 12"; 1Ib). This is part of the Electrostatic Lab |
|
ELECTROSTATIC KIT
Electrostatic Kit Everything you'll need to explore static electricity! This economical set of materials is ideal for demonstrating static electricity. Each kit is supplied with - three friction rods: one hard rubber, one hollow glass and one half ground glass
- four pads: one fur, one flannel, one silk, and one wool
- 3 balloons and 10 feet of string.Instructions provided.
(8-1/4" 1" .25lb). |
|
Friction Pads
Use with friction rods to generate electrostatic charge. |
|
Friction Rods
Low-cost and applicable to a variety of static electricity applications! |
|
ELECTROSTATIC LAB
Electrostatic Lab
An incredibly comprehensive kit for studying static electricity! This kit includes items for Faraday's ice pail experiment: two electroscopes with interchangeable spheres and disks are included to demonstrate charging by induction, repulsion and attraction of charges, discharge occurrences from points, surface distribution of charges and charging properties of different materials. Also included is an electrophorus, Faraday cage, electrostatic balls, neon lamp, transfer ball, various friction rods and instructions. (12" x 12" x 12" 5.3lb). |

Wimshurst Machine & Supplies
Deluxe - (Wimshurst Machine) The classic generator for producing electric charges and high voltage sparks! The unit is built with cast-iron supports and pulleys. The Leyden jars are large-sized and the disc is a clear acrylic material. Solid aluminum segments are mounted on the external side of each disc. This is an improvement
over the aluminum foil that is common with other units.
Instructions provided. (14" x 8-1/2" x 14-1/2"; 6-1/4lb). |
|
Wimshurst Machine - Economy & Supplies
Economy (Wimshurst Machine) Perform all the classic experiments at a more affordable price! This unit is built following the basic design of most Wimshurst machines, with economy in mind. The stand, Leyden jars, pulleys, and two handles are all molded from durable plastic. Produces sparks 2-1/2" long, under appropriate weather conditions. (6lbs). |
|
LEYDEN JAR
Separable Leyden Jar
Demonstrate storage of electrical charges! This unit is effective in helping students to understand the function of a dielectric and the buildup of static electricity. The inner and outer metal conductors are separated by a plastic insulator cup. These pieces slide easily in and out of one another. The inner conductor may be removed and the charge measured. When the conductors are replaced the charge is transferred back to them. 3 piece set. Instructions provided. (3"diameter and 5 3/4" overall height; .5lb). |
