BioPAT® Trace Membranes Dialysis Bypass Glc/ Lac low control

The dialysis measuring method using the dialysis probe involves the transfer of analytes through a dialysis membrane in the dialysis probe which separates the reactor contents (medium) from the acceptor stream. At the same time, the dialysis membrane functions as a sterile barrier. n addition to the standard membrane, there are special membranes available:

• Cellulase resistant membrane for cultures, in which cellulases are released during the process (primarily microbial cultures).
• Gas diffusion membrane for samples with volatile components (e.g. methanol and ethanol).

• The by-pass loop functions when sterilization or a technical limitation exists that a probe cannot be installed in the vessel. It functions on the same principles as the dialysis probe with the membrane contact surface installed into a flexible tubing line with a 6 or 9mm hose-barb connection.
