Millikan's Apparatus allows for the atomization of a latex solution into tiny spheres, while the rubber hose charges them with static electricity. The spheres are then inserted in a cell formed by two charged plates. When the voltage between the plates is reversed, the particles are drawn to one plate or the other.

A. Without Power Supply

The rubber hose charges the particles and they are then placed between two charged plates in a cell. By reversing the voltage between the plates, the particles are drawn to one side or the other. A small telescope with a graticule is used to observe their motion. The calculation of the charge on a single electron can be determined by measuring the potential of the cell plates and plotting the velocities of the spheres. External power sources need to be connected.

Includes: 

  • Sockets for connecting to 12V.AC / DC at 3A for illuminator
  • Sockets for connecting a high voltage DC power supply
  • Knob to adjust cell voltage from 0-300V.DC
  • Switch to reverse voltage polarity
  • Sockets for a student bench meter or multimeter

B. With Power Supply

Using a rubber hose, a static charge is induced upon the spheres before they are introduced into a charged plate cell. By reversing the voltage between the plates, the particles are attracted to one or the other. The movement of the spheres can be observed through a small telescope with a graticule, and the built-in power sources allow for easy measurement of the charge on a single electron by plotting their velocities. 

Includes:

  • Switch to reverse the polarity on the cell
  • Knob to adjust the cell voltage from 0-300V.DC 
  • Sockets for a student bench meter or multimeter
Dimensions:  300m (L) x 165mm (W) x 165mm (H)

Decent quality for the price
Color: Grey
Decent quality for the price. Other privacy screens were extremely out of my budget, but this looks and works just fine- I just needed something simple to place behind my couch to hide some clutter. It took me about a half hour to assemble, but it was easy enough. It might be due to my carpeting, but I don't trust that the screen would be stable enough to stand freely without falling. Thankfully my plan all along was to wedge the screen between the couch and a box of clutter anyway, so for me it works as l'd planned!

Overpriced but effective.
Color: Cream
I happened to get lucky and get a warehouse deal at an additional 30% discount. Even at $25, it feels a little overpriced. But it was easy to assemble and serves its purpose. If you line the Velcro up exactly, the panels sag, if you stretch past even, but where it still grips, they look pretty ok. It is very light and does fold very compact for easy storage.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy
