The Flow-through oxygen mini-sensor (FTC-PSt6) is a miniaturized fiber optic chemical sensor integrated in a T-shape flow through cell.
The flow-through cell is connected to the oxygen meter Fibox Trace by a polymer optical fiber (POF) with 2 mm diameter as a light guide. A glass tube with 2mm inner diameter (4mm outer diameter) is coated with oxygen sensor at its inner wall. The volume for liquid inside the FTC cell is about 100 (±10) microliter.
The standard T-shape flow cell can be easily connected via Luer-Lock adapters to external tubings. Liquids (like water, blood, etc.) can be pumped through the cell. This type of oxygen sensor has an excellent long-term stability.
