ELECTROSCOPES
#501-5 Electroscope, Flask
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.
#501-6 Electroscope, Rod Assembly. With Alligator
Clip
#501-11 Electroscope, Rod Assembly. With Nail
Head
#501-7 Electroscope, Metal Case.
This electroscope box is made of anodized aluminum
with glass windows. The glass plates prevent an erratic motion of
the leaves by shielding them, thereby causing leaves to react only to charges
which are intentionally brought near them. Size 5 1/8" x 3 5/8".
Instructions provided.
#501-8 Electroscope, with Electrostatic Balls.
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.
#501-8A Electroscope, Silvered Electrostatic Balls Only.
#501-9 Electroscope, Enclosed Unit.
A brass ball sits atop a plastic cap, from which
very fine copper wires are suspended and to which the electrostatic balls
are attached. The entire unit is sealed in a clear, plastic cylinder
which shields air currents. Instructions are provided.
#501-12 Electroscope, Solid State.
Use either the built in LED or attach your own
meter to measure electrostatic changes up to three feet away. Built
using solid state circuitry and requires one 9 volt battery. Instructions
provided.
#501-FOIL Electroscope Foil Only. . .pk/12
#501-13 Electroscope Case, Gold Foil Type
Gold Foil Electroscope is a classic in physics
demonstrations and science classes. This unit is bigger and easier
for the student to use than the regular Flask Electroscope. The leaf
is a little larger and the wide radius of swing provides a visual and sensitive
unit. The metal case is strong and stable to resist damage.
#510 Leyden Jar, Separable
This unit is effective in helping students to understand the function
of a dielectric and the build up 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
ELECTROSTATIC SETS
#506 Electrostatic Kit.
This economical set of materials is ideal for
demonstrating static electricity. Each kit is supplied with 3 friction
rods, one fur pad, flannel pad, silk pad, wool pad, 3 balloons and 10 ft
of string. Instructions provided.
#507 Electrostatic Lab.
This kit includes 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.
#508 Wimshurst Machine, Deluxe
For generating electric charges and high voltage
sparks. The unit is built with cast iron supports and pulleys.
The leyden jars are a large size and the disc is a clear acrylic material.
On the external side of each disc, aluminum segments are mounted.
This is an improvement over the aluminum foil that is common with other
units. Dimensions: 345mm x 345mm x 395mm. Weight 2.05
kg. Instructions provided.
#508-BLT Wimshurst Machine, Belt Only
#508-BSH Wimshurst Machine, Brushes Only
#508-LJ Wimshurst Machine, Leyden Jar Only
#509 Wimshurst Machine, Economy
This unit is built following the basic design
of most Wimhurst machines but 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 conditions.
#1869 18th Century Electrostatic Machine.
The Electrostatic Kit (developed by the Bakken
Institute) is introduced by a professional videotape demonstrating crucial,
early, experiments, using authentic equipment. A curriculum book
guides the instructor and students through the experiments. The kit
includes most of the apparatus found in an electrical laboratory of the
18 century. Included are rods and cloths for producing vitreous and
resinous electricity.
#505 Faraday's Cage Kit.
Teachers will find the demonstration useful in
the study of potential build-up inside a conductor cage. Two experiments
that can be performed are the lightening rod effect and surface charge
distribution. The unit measures 270mm x 120mm. Instructions
included.

#501-14 Van de Graaff Generator with accessories
Introducing a new Van de Graaff Genrator 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.)
