But not to worry; no one will notice.

Super April Sale! Yes, April comes once a year.


If you've ever been embarrassed by demonstrations that didn't (or if you've ever occasionally faked results) then you need ideal equipment. No teacher should be without an adequate stock of ideal equipment. We guarantee the textbook results every time. It's easy to use, inexpensive, and it works!

IDEAL HOOKIAN SPRINGS Throw out all those stretched springs
and replace them with IDEAL Hookian Springs.

Are you tired of replacing laboratory springs when students extend them beyond their elastic limit? Our IDEAL Hookian springs are the answer to your problems. These springs may be extended to 10100 percent of their original length, and will return to their original length without fail. Hysteresis is no longer a problem! Perfect for experiments on Hooke's law, simple harmonic motion, etc.

$100 each, a bit pricey, but weigh that against the continuing cost of replacing ordinary springs.


We've been searching for a supplier of these for many years. Finally, you can throw away those heavy bar magnets and replace them with these compact magnetic field sources. Positive and negative monopoles are shipped separately, and the user must assume responsiblity for keeping them from getting near each other. Due to their mutual repulsion, each kind is shipped in a very strong box made of our perfect magnetic shielding, also useful for other experimental purposes. Guaranteed 1/r2 fields to 0.1% when isolated from other magnets, or measured within a fully enclosing magnetic shield (the shipping container is fine for this). Exercise great care when opening the shipping container Exercise great care when opening the box.

$2000/dozen. Shipping, $5000.


Essential equipment for studies of motion and mechanics. All of Newton's Laws can be easily and correctly demonstrated with the aid of an ISE frictionless plane (together with some or all of the other items shown in this catalog). Available in any size up to 3m2m! Just send us your specifications!

SALE PRICE...$16.95/m2 (Cutting charges extra.)

Call for prices on perfectly rigid friction backing to achieve perfect flatness and secure positioning. In this form we can provide leveling feet, and handles at any location you desire. We can also drill holes around the perimeter for permanent positioning.

The ISE perfect spirit level may be used, but leveling may be easily achieved by simply placing any small object on the sheet and adjusting the legs until that object executes simple harmonic motion about the center of the sheet.

How does one get off of a frictionless plane? How does one get on it?

This box may not appear full, 
due to settling in shipment. POINT PARTICLES

Another "must" for proper mechanics demonstrations! ISE point-particles (integral numbers of grams), are available in all masses from 1g to 10kg. Buy the 10kg box and SAVE!

SALE PRICE...$11.65/10kg


We are the sole supplier of this unique product (made by us under licence granted by Bernoulli International). Completely free of viscosity and totally incompressible, it is otherwise indistinguishable from ordinary water.

SALE PRICE...$850/bbl.


Have you ever had a demonstration fail due to non-rigidity of an essential part of your apparatus? This can be both frustrating and embarrassing, but is it a soluble problem! An ISE rigid body NEVER flexes! We can cut and machine this material to any desired specifications. Specify precise dimensions when requesting an estimate.

SALE...20% off regular prices.

Styled after the original design. GAMMA-RAY MICROSCOPES

A popular standby. No laboratory is complete without it! GUARANTEED to satisfy all textbook specifications for pulley problems. This string is completely inextensible, weightless, and perfectly flexible. Buy it by the 200m reel. These pulleys also have frictionless bearings.

SALE PRICE...$6.47/reel


Everybody said it couldn't be done! We are extremely proud of this new addition to our catalogue, and we are certain that ISE inertialess pulleys will soon revolutionize the art of physics demonstration. Price proportional to square of radius. Use with frictionless bearings (below) for best results.

Harvested from trees grown from scions of the original apple tree in Newton's backyard. Subject to the strictest standards of quality control, each box contains 4 dozen apples, individually wrapped.

SALE PRICE...$19.85/box

BONUS! A frugal researcher named Dave 
Set up his lab in a cave. 
   His experiments were few 
   And failed peer review, 
But think of the money he saved. With every order over $35.00 we will send you, ABSOLUTELY WITHOUT CHARGE, one cylinder (5 liters at 25 atm.) of IDEAL GAS. Demonstrating gas laws need never again give you heartburn!! Manufactured exclusively by ISE.

BUY NOW! You won't be around to see the next millenium.

FOR SERIOUS RESEARCHERS WHO WON'T SETTLE FOR LESS THAN IDEAL RESULTS. Our line of research apparatus is second to none, because it's IDEAL!

When anything less than perfect 
just isn't good enough.


Also see black holes.

$500/dozen. (Buyers must enclose proof that they are over 21 years of age.)


Our standard model heat sinks now have infinite capacity (2%). If you have the time and the energy we invite you to test their capacity yourself. $3000.00 each

New Improved Model Perfect Heat Sink is supplied in Formica with simulated chrome trim. $4000.00 each


Perfect for cleaning up those seemingly insoluble problems messing up your lab. $10/liter


Frankly we don't know what uses these might have. We bought the entire inventory of a bankrupt manufacturer. They are cluttering our warehouse so we have priced them to move out fast. You might say these are budget paradoxes.

$1/pair (as is, no guarantees)


These engines operate silently and never need lubrication. Guaranteed efficiency of (1 - Tc/Th). Can be run in reverse to cool the lab in summer. Use with our perfect heat sinks for best results. $2,000.00

Occam had a tough beard.

Occam's original razor,
from the Ideal Scientific Equipment Company museum collection.

OCCAM'S RAZOR For a really close shave, 
use an OCCAM razor.

The basic model introduced by Occam has been greatly improved by the Swiss craftsmen in our Hong Kong manufacturing facility. Blades of finest Swedish surgical steel (imported from Japan). Perfect for slicing through obfuscation, severing red tape, and cutting up a colleague's pet theory.

$75.00 ea. Extra blades $5/doz.


A space-age concept finally brought down to earth. Every lab needs one, and one is quite sufficient, so we sell them singly only. Thousands of uses. A perfect way to dispose of your used Occam's razor blades, unwanted surplus equipment, OSHA inspectors and annoying lab visitors. Replaces administrator's paper-shredders--will even neatly dispose of the old shredder. Permanently dispatches into oblivion unwanted lab data which won't fit theory. Caution: Not for children. Swallowing hazard.

$999.99 each

Includes a safety brake 
so it won't spin dangerously fast. PERPETUAL-MOTION MACHINE

This precision machine will be a real conversation piece sitting on your desk or lab bench, turning silently and forever. Crafted of gleaming stainless steel on a polished walnut base. Absolutely noiseless and vibration-free. While entropy increases all about you it is comforting to relax and watch this precision mechanism spin eternally. This is a perpetual-motion machine of the first kind, therefore it is in continual motion but produces no useful work. This might be a metaphor for much of what goes on in the modern workplace. Includes plastic dust-cover. Batteries not required.

This new model is based on a design by Bob Schadewald, modernizing the classic overbalanced wheel. Frictionless steel rollers ride silently around the specially shaped cutouts in the wheel, ensuring that there's always more weight on one side of the wheel. You may see a larger and more detailed picture of this magnificent machine by clicking here. [Picture © 1992 by Bob Schadewald.]
