Cell-Free Sampling Probes
Operation of the FISP®
The FISP® is sterilized in the vessel with the probe immersed in the fermentation
broth or culture media. A peristaltic pump (or the vessel's own hydrostatic pressure)
withdraws a sample through the tubular membrane and into the probe's
stainless steel network of grooves. The sample flows through the network of grooves
into a central channel where the cell-free sample can be directed to an on-line
analyzer or fraction collector or sample container.
The sample flow rate is dependent on the media viscosity and other fluid properties.
The maximum achievable flow rate is 5 ml/minute, although typical flow rates range
between 0.4 - 2.0 ml/minute.
