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).7-501-6
METAL CASE ELECTROSCOPE
ElectroscopeMetal 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 BallsA 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).
7-501-8A
ELECTROSCOPE ENCLOSED
ElectroscopeEnclosed 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 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).
Wimhurst Machine & Supplies
Deluxe - 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).

LEYDEN JAR
Separable Leyden JarDemonstrate 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).
