Trace | Multi Trace Operating Instructions 29
Design and Function
The BioPAT
®
Trace | Multi Trace can optionally be attached to laboratory
stands, suspension bars or benchtop stands. A corresponding stand clamp
and a suitable benchtop stand are available as accessories.
CAUTION
Risk of damage due to incorrect connection!
Under no circumstances should a voltage source be connected to the analog
data outputs at the rear of the BioPAT
®
Trace | Multi Trace. This also refers to a
multimeter for resistance measurement. If a multimeter is used to measure
the voltage or current, the contacts to the BioPAT
®
Trace | Multi Trace must
be removed before changing the measurement range on the multimeter.
Otherwise, there is a risk of the device being damaged.

Trace | Multi Trace Measurement Methods
BioPAT
®
Trace | Multi Trace enables the online sampling method of dialysis
using the dialysis probe.
The simplest method is to directly measure a filtered sample of medium.
However, because reactor medium is used, the range of applications is limited
to processes for which there is a sufficient reactor volume or which allow
continuous-feed.
Dialysis sampling is an option when processes are involved for which the
reactor volume does not allow enough sample material. This method only
removes low molecular substances from the reactor medium, without
reducing the volume of fluid. The following figure shows a photographic
representation of how the BioPAT
®
Trace can be connected to a bioreactor by
way of a dialysis probe.
