Polarographic Oxygen Electrodes

Instech's Clark style polarographic electrode measures 1.625" (41.3 mm) long by 0.125" (3.2 mm) in diameter. The cathode is an exposed section of 0.005" (0.1 mm) pure platinum wire in a fused glass seal.

 

NOTE: In 2011 Instech's polarographic systems were discontinued and replaced with fiber optic fluorescence lifetime systems.
