Glass chamber with mL measuring cell and water jacket, for determining oxygen consumption of small aquatic animals (e.g. fish larvae or tissue samples) or do blood gas analysis for determining total oxygen and carbon dioxide content of small blood samples, e.g. method by Tucker, 1963.
This water jacketed measuring cell is for use with fiber optic sensor spots for oxygen measurements in tiny fluid samples at any environmental temperature.
The sensor spot is glued onto a glass base and the external fiber cable is fixed with a (red) fingers screw.
An acrylic lid with a hollow forms the 35 µL measuring cell and it is easy to change the volume and shape of this insert, thereby having cells for a range of applications and/or sample volumes.
The samples can be injected directly into the cell or through a stainless coil inside the water jacket that has fittings for Ø 10 mm tubing.
