Single-use dialysis probe

Single-use dialysis probe for sterile online sampling

For single-use bioreactors TRACE offers its patented single-use dialsyis probe design for a variety of single-use reactor systems and geometries. These can be combined with the online analysers TRACE C2 Control, TRACE M4 or MultiTRACE.

The single-use dialysis probes can be mounted into the reactor bag using existing sampling ports. When mounted the manual sampling port is still accessible through a needlefree sampling valve and an additional inlet and outlet for the dialysis sampling is provided. 

The probe is gamma irradiatable and can be mounted at the manufacturer site. Alternatively it is shipped as sterile device, which can be mounted at customer site under the clean bench.
