For PO2 measurement of blood or other fluids, or for microflowcell use.
The all-glass sample chamber has a capacity of approximately 70µl. Samples are injected into the chamber via a 1 mm stainless steel tube fitted with a fine p.v.c needle-locating collar.
The sample leaves the chamber through a glass Luer fitting to which a small bore flexible drainage tube can be connected. The sample chamber is completely surrounded by water circulated through the glass water jacket from a constant temperature bath. This provides good temperature regulation whilst providing excellent visibility of the contents of the chamber. The water jacket screws into an acetal base section and can be easily removed for cleaning.
The microcathode electrode fits into the central electrode holder and the membrane at its tip forms the floor of the sample chamber.
