Sartorius BioPAT Trace - Particle Filter Function

34 BioPAT
®
Trace | Multi Trace Operating Instructions
Design and Function
If air bubbles are present in the conductivity cell after connecting the dialysis
probe, then it would be advantageous to operate the system in measurement
mode with maximum measuring frequency for a period of approx.
30minutes.
CAUTION
Erroneous calibrations due to air bubbles!
If there are air bubbles in the measuring cell, under no circumstances should
calibrations or reference measurements be carried out, as these may be
erroneous and subsequently lead to incorrect results.
4.4 Particle Filter Function
The particle filter is part of the tubing set. It fulfills two tasks in the BioPAT
®
Trace | Multi Trace. First, sterile filtration of the buffer solution is performed
through the membrane with a pore size of 0.22µm. Before the solution leaves
the module, a second membrane is used for degassing. Thus, the particle filter
ensures that the acceptor stream in the BioPAT
®
Trace | Multi Trace stays free
of particles and air bubbles.
t To ensure proper operation of the measuring instrument, the tubing set,
including the particle filter, must be replaced regularly.
