Conductivity of Solution with Glass Jar
Code: CHEC001
Pure water does not conduct electricity very well. However, when certain substances are dissolved in water, the solution does conduct electricity. You can make a simple device that shows how well a solution conducts electricity. This device uses a flashlight bulb to indicate how well the solution conducts electricity. The better the solution conducts electricity, the brighter the bulb will glow.

Brownlee Electrolysis Apparatus
Code: CHEC031
This is the simplest type of electrolysis apparatus. Platinum electrodes are attached to insulated connecting rods which are attached to binding posts mounted on a non-conducting support. The support rests across the top of a battery jar (not included) and has 2 clips that hold 2 inverted test tubes. The unit operates on a 6V battery or 10V. DC power supply
Contemporary Brownlee Apparatus
Code: CHEC036
Brownlee Electrolysis Apparatus: New Design! This unit features several improvements over the standard Brownlee. The open front spring clips make it much easier to remove the test tubes while the tubes remain submerged. The test tubes have been graduated for a clear measurement of the volume of gas generated. The black acrylic background aids in viewing the water level while supporting the test tubes. The binding posts have been repositioned for easy access and greater safety. The unit measures 140mm x 203mm x 38mm. Instructions included.
Brownlee Electrolysis Apparatus
Code: CHEC041
Perhaps this is the most budget Brownlee apparatus. Two tubes are held in place over the electrodes with clip supports, making it easy to collect H2 and O2 from electrolysis of water.

Simple Type Electrolysis Apparatus
Code: CHEC056
A simple type of electrolysis apparatus with platinum electrodes attached to insulated connecting rods which are attached to binding posts mounted on a non conducting support. The support rests across the top of a battery jar (not included) and has two clips that hold two inverted test tubes. The unit operates on a 6V battery or 10V DC power supply.
Electrolysis Apparatus with 6 Electrodes
Code: CHEC061
Electrolysis cell apparatus with 6 electrodes and an electrolyzer. It is ideal for demonstrating the characteristics of a primary cell.
Potato Clock - Electrochemical Cell Type I
Code: CHEC066
This kit demonstrates how two potatos power a clock which actually is a electrochemical cell. Other fruits such as apple, lemon, etc can also be used to make a electrochemical cell. Transfer of electrons between the zinc galvanized nail is inserted into a potato and the copper wire is inserted another potato. The potato conducts electricity, keeps the zinc ions and copper ions separate, so that the electrons in the copper wire are forced to move thus generate current.
Potato Clock - Electrochemical Cell Type II
Code: CHEC071
This kit demonstrates how two potatos power a clock which actually is a electrochemical cell. Transfer of electrons between the zinc galvanized nail is inserted into a potato and the copper wire is inserted another potato. The potato conducts electricity, keeps the zinc ions and copper ions separate, so that the electrons in the copper wire are forced to move thus generate current. Other fruits such as apple, lemon, etc can also be used here to replace potato electrochemical cell.
Potato Clock - Electrochemical Cell Type III
Code: CHEC076
This kit demonstrates how two potatos power a clock which actually is a electrochemical cell.Transfer of electrons between the zinc galvanized nail is inserted into a potato and the copper wire is inserted another potato. The potato conducts electricity, keeps the zinc ions and copper ions separate, so that the electrons in the copper wire are forced to move thus generate current.
