ENZYME ASSAYS - MEASURED BY CHANGES IN SOLUTION CONDUCTIVITY

 

Simple, Sensitive, Low Cost (ca. £200) &  Reliable

 

                     EASY TO BUILD

 

                PCB available soon

 

[It takes longer than I expected to design and implement an effective PCB - I am just starting the second design cycle which will require another fabrication etc. It will be worth it in the end!!]

 

 

Can be used for: Blood & Urine Clinical Tests, Industrial,

       College & School projects [see APPLICATIONS]

 

Uses two low cost electrochemical cells (Sample & Reference) in an ac bridge for extra differential sensitivity

 

The simple bridge circuit & the apparatus are shown below
