Small Sample Chamber Systems

Each chamber system consists of an anodized aluminum chamber block with connections for circulating water to keep the electrode and sample at a constant temperature. The chamber systems are compatible with our standard polarographic electrodes and the new fiber optic sensors. They can be set up in two basic configurations:

(1) Batch Cell Mode

For measuring oxygen consumption in a sealed 600 microliter 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.

(2) Flow Cell Mode

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. Separate high and low flow cells cover a range of flow rates.

Low flow cell is typically used unless flow rates past electrode tip are greater than 15 ml/min (graph applies to polarographic electrodes only).

The chamber blocks by themselves are sold in two configurations*

600BH - Chamber block with batch and flow cells

600FH - Chamber block with flow cells only

Electrode, stirring assembly and stirring controller are not included in these part numbers; if needed, order separately or order part number SYS600.
