Millikan Apparatus with Power Supply

Millikan Apparatus with Power Supply

Millikan Apparatus with Power Supply

Accurately determine the elementary charge of the electron and demonstrate quantization.
- Whole-plate reversible polarity electrode chamber provides a completely uniform field
- High intensity LED light source brilliantly illuminates particles and is fully adjustable for beam focus and background contrast
- Short depth-of-field viewing scope with reticle allows coarse and fine focus, with scanning of the particle cloud for individual particle selection

Think this classic of modern physics is out of reach in your classroom? Think again.

Focus on results, not set-up and clean-up.

Assembly takes seconds and actually becomes part of the instructive process: students attach the two main components guided by the case image - a schematic of the experiment. The latex microsphere suspension - instead of oil - means clean-up takes only moments
with distilled water.

Classroom efficiency. Budgetary economy.
No need to buy and arrange a power supply, leads, voltmeter, probes, or ringstand means

both class time and class dollars go farther.

A Wish To Comply
Robert Frost

Did I see it go by,
That Millikan mote?
Well, I said that I did.
I made a good try.
But I'm no one to quote.
If I have a defect
It's a wish to comply
And see as I'm bid.
I rather suspect
All I saw was the lid
Going over my eye.
I honestly think
All I saw was a wink.

We think if Mr. Frost had used our apparatus,
his poem may have gone a little something like this:

I saw them this time,
Those pinpricks of light!
With a flick of the switch,
I studied their climb.
There were hundreds in sight.
This classic of e,
A research sublime,
Went without a glitch.
We found easily
With nary a hitch
That constant so prime.
It took but one try.
Who needs Millikan's eye?
