Claims

1. IN A FLOW CELL FOR ELECTROCHEMICAL MEASUREMENTS, THE COMBINATION OF:

A BLOCK OF ELECTRIC INSULATING MATERIAL HAVING A CANNULA THERETHROUGH, AND FIRST AND SECOND ALIGNED PASSATES ON OPPOSITE SIDES OF SAID CANNULA COMMUNICATING BETWEEN SAID CANNULA ND THE EXTERIOR OF SAID BLOCK, WITH SAID FIRST PASSAGE HAVING A TAPER CONVERGING TOWARD SAID CANNULA;

FIRST ELECTRODE MEANS POSITIONED IN SAID FIRST PASSAGE AND HAVING AN END, SAID FIRST ELECTRODE MEANS HAVING A MATING TAPER FOR CLOSING SAID PASSAGE AND FIXING SAID END OF A PRDETERMINED POSITION SUBSTANTIALLY AT SAID CANNULA;

SECOND ELECTRODE MEANS ELECTROLYTICALLY CONNECTED TO SAID CANNULA;

AND A MOVABLE MEMBER POSITIONED IN AND CLOSING SAID SECOND PASSAGE AND HAVING AN END, SAID BLOCK AND SAID MOVABLE MEMBER INCLUDING ADJUSTMENT MEANS FOR SELECTIVELY POSITIONING SAID MOVABLE MEMBER IN SAID SECOND PASSAGE WITH THE END SUBSTANTIALLY AT SAID CANNULA FOR CONTROLLING THE RELATIVE POSITION OF SAID ENDS.
