From ABER Instruments’ range of Biotech Equipment products, the Standard Futura is suitable for most bioreactors and is ideal for 25mm diameter side mounted probes and 12mm. (Supplied with a 2 metre cable).
|Frequency Range:||50KHz to 20MHz|
|Measuring Ranges:||Capacitance: 0.0 to 400pF/cm
Conductivity: 1.0 to 40 mS/cm +/-0.1 mS/cm
(Higher ranges available with compatible probes)
|Cell Concentration Range:||Depends on cell sizes but typically:
Yeast (6 µm): 106 cells/ml to 1010 Cells/ml
Bacteria (1 µm): 109 cells/ml to 1013 Cells/ml
Animal Cell (12 µm): 105 cells/ml to 109 Cells/ml
Plant Cell (50 µm): 103 cells/ml to 107 Cells/ml
|Resolution:||Resolution: 0.1 pF/cm.
Bacteria typically 0.1 g/L dry weight or 2×109 Cells/ml for E. Coli.
Yeast or Animal Cells 0.05g/L or 1 x105 Cells/ml
The relationship of these capacitance values to biomass levels depends upon the
cell type and line.
|Accuracy:||Typically bett er than ± 3% or ± 2% of the reading|
|Stability:||Better than ± 0.2 pF/cm at constant temperature with standard conductivity solution of ~12 mS/cm|
|Linearity:||Better than ± 1% over 100 pF/cm|
|Precision:||Typically <±0.5 pF/cm, no filter active.|
|Power Supply:||Natively 24V DC. This is typically supplied by an Aber Hub running on 110V AC to
240V AC mains.
Recommended ambient operating temperature range: 5°C to 40°C
