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.

Continuously Variable Transmission (CVT) – Banned!

We know an engine can perform much more efficiently if it doesn’t need to accelerate and decelerate while switching gears. This is the purpose of the Continuously Variable Transmission (CVT) and is the reason it was banned from Formula One racing in 1994.  It’s operation is so smooth and effortless it was thought to take the sport out of that racing pastime.

However, CVT’s are still used in tractors, snowmobiles, motorcycles, go-karts, Formula 500 cars, and a host of other transportation vehicles and machines.

The uses for a CVT listed above can be easily examined and seen from the inside out using the ND11068 – Continuously Variable Transmission (CVT) Gearbox Cut-Away from NADA Scientific.  It allows you to engage the CVT through an electromagnetic clutch, forward and reverse insertion lever, primary pulley, secondary pulley, roller belt, final reduction unit, and a hydraulic command unit.  It’s mounted on a stand with wheels and is operated manually by hand crank to allow you to determine the speed and monitor safety.
