Electric Separation – Hydrogen and Oxygen Up Close!

Thinking about potassium, we’re sure.

Starting in 1807, Sir Humphry Davy used electrolysis to discover a myriad of elements. He used this process to uncover what we now take for granted as potassium, sodium, barium, calcium, chlorine, and magnesium among others.

The process Davy’s used has largely remained unchanged and can be followed by you and your students using the following Electrolysis Apparatus Unit (N99-B-2637-040) found at NADA Scientific.

The electrolysis apparatus is used to demonstrate experiments in electrical charge/discharge and energy conversion. It features a main unit made of AS resin with fixed stainless steel electrodes, graduated test tubes (2), and a resin test tube holder. The compact design makes these units stackable for neat and easy storage.

If you’re looking for a suitable power source, it can also be purchased with the GENECON12  as a set to create the entire lab experience of separating water into its component gases.

Give Thanks for Direct Current!

November 27, 2013

It’s been just over 131 years since Thomas Edison’s Edison Electric Illuminating Company established the world’s first investor-owned electric utility station on Pearl Street in New York City.  On September 4, 1882, the Edison Illuminating Company switched on power to 59 customers in lower Manhattan, providing them with 110 volts of direct current (DC)!

Whether you’re a member of Team Edison or Team Tesla, we think both would agree that the GENECON12 is a fascinating tool to communicate the basics of how direct current works.

ImageWhile it won’t power homes in your neighborhood, it will provide 12 volts of hand powered direct current with changing polarity depending on the direction you turn it.  The GENECON12 produces approximately 200mA of usable current and when connecting one GENECON to another or to a low power source, it will act as a motor.  That’s only one of 22 experimental uses!

Click on either of the pictures to learn more about the GENECON12 as well as other products from NADA Scientific. Receive a complimentary Adventures with the GENECON Activities Book ($10 Value) with your purchase of 1 or more GENECONS.


Planets

June 4, 2010

This month is going to be the month to see the planets. It depends when a person is able to look at the sky, to determine what planet they will be able to see. I am looking forward to observing: Venus before sunrise or sunset; Saturn in the late evening sky, and lets not forget Mars, Mercury, Jupiter, and Uranus.


When we tested the Hamilton flywheel for the static high voltage GENECON, we found that the flywheel did not rotate at all. Is there any know-how?

Note that: When assembling the support shaft for the flywheel, install them firmly. When the surface of polyvinyl chloride sheet supplied with the equipment is wet, leak current flows (electric leakage). Remove moisture using alcohol or the like. Place the rotation part on the top end of the support shaft in parallel with the floor in a wobbly condition.


We want to replace felt fot static high voltage GENECON. Please provide instructions for replacement.

October 17, 2008

Do not replace the felt by yourself. Otherwise the performance of the equipment may deteriorate. In addition, replacement or modification of the product by the customer invalidates the warranty.
