These flat electrodes were designed for the Hoffman Electrolysis Apparatus. The platinum lead wires are sealed in glass tubes. The glass tubes are inserted in No. 1 rubber stoppers. These electrodes will fit SB11120M and SB10809M listed.

This complete apparatus will demonstrate the decomposition of water (separation of oxygen and hydrogen). Each of the glass tubes has stopcocks and is graduated to give precise measurements. The tubes are mounted on a special stand which is fitted with b..

This specially designed, heavy metal support has binding posts in the base and double clamps on the rod. A special clamp with prongs for supporting the lower part of the apparatus is also supplied. The stand will hold the apparatus securely without caus..

The graduated “U” tube with stopcocks and the glass thistle tubes are included. These are the same parts used in the complete apparatus (SB11120M). Graduated 50 ml in 0.2 ml.

Grades 7-12.
The most popular form of electrolysis apparatus. Consists of electrodes attached to insulated connecting rods connected to terminals, all mounted on a nonconducting plastic holder. Designed to rest on top of a glass jar or b..

A simple type of electrolysis apparatus, but demonstrates the principle as efficiently as other expensive apparatuses. Consists of a plastic container measuring 3" dia. x 2-1/2" H, total height 3-3/4", with mounted carbon electrodes...
