Harvard/Instech Oxygen Monitoring System Accessories

The 61-0130 is a complete, flexible system designed for oxygen measurement in small samples, as is frequently required in biological research. The system is designed around our miniature Clark-style polarographic electrode. Measuring only 1/8 of an inch in diameter (3.2 mm), it is ideal for metabolic studies of mitochondria, cell suspensions, and enzyme assays. This system includes everything you need for oxygen measurement on two independent channels: a dual channel amplifier, two oxygen electrodes, and two chamber systems. It also includes accessories to simplify electrode maintenance.

The system is designed around our miniature Clark-style polarographic electrode.

This system includes everything you need for oxygen measurement on two independent channels: a dual channel amplifier, two oxygen electrodes, and two chamber systems. It also includes accessories to simplify electrode maintenance. The chambers can be set up in two basic configurations.


Flow Cell Mode is for in-line measurement of oxygen in solutions flowing past the electrode. This set-up is often used to measure oxygen uptake of perfused tissues by measuring inflow pO2 with one channel, and comparing it with the outflow pO2 as measured by the second channel.


Batch Cell Mode is for measuring oxygen consumption in a sealed 600 µl sample. The batch cell chamber includes a magnetically-coupled stirring system, connections for circulating water to maintain a constant temperature, and a unique window-valve for filling, rinsing, or injecting solutions into the chamber. For continuous flow of water use our 66/77 Peristaltic Pumps, not included.
