This electrode holder is made for GoodVitality by Commercial Science (www.comsci.org.uk) and was first shown at the Becks Training day. It was so popular several people wanted to steal it!.
It is very simple to use and works really well with our Pyrex beaker. It is now all plastic - no metal at all which could possibly contaminate your solution. The white plastic nylon material is perforated with holes to let water vapour escape easily.
The electrode holder is 120 mm from side to side. It will hold electrodes of any length
Please note this does not include the silver electrodes - it is only the Electrode holder.
