DESCRIPTION
 
Complete setup instructions and sample experiment included. The Hoffman Electrolysis Apparatus is used for the qualitative and quantitative study of the electrolytic decomposition of electrolytes such as water and hydrochloric acid. When fully assembled, this large demonstration device measures @24" in height. The unit consists of two vertical 50ml graduated glass tubes, with stopcocks at the top. The vertical tubes are joined by a bridging tube to a central reservoir. Each vertical tube is fitted with an electrode that extends through a rubber stopper, so that only the electrode comes in contact with the electrolyte. External connections are facilitated by two screw terminals (positive and negative) mounted on a cast iron base. The support stand is designed for safe and simple clamping. Delicate glass parts are packaged in a custom styrofoam storage box for safe transport and storage.

Carbon electrodes are included with the device by default and unless otherwise selected. You may select your electrode type (Carbon or Platinum) when adding this item to the shopping cart.

Requires a 6 - 12V low voltage D.C. power source for operation such as a battery or laboratory power supply (not included).

Hoffman Apparatus March 12, 2019
Reviewer: Anonymous Person from Reading, PA United States  
Great for application of introductory electrochemistry concepts and phenomena. Use a clamp than the aluminum clips it comes with since its difficult to remove from clips.

Very Late Delivery/No Communication March 9, 2019
Reviewer: James LeBlanc from Pacifica, CA United States  
I ordered an apparatus for a high school demonstration in the first week of January and didn't hear it was shipping until March. I sent an e-mail asking about it in the first week of February and got no reply. I finally heard from the company after it was delivered and was sent some electrodes, but never got an explanation about why it was so late and why no one replied to my initial question. I don't think I will be ordering from you again.
