Sampling Accessories

The different bioPROBE versions can be adapted to your specific process or any other individual mounting situation with simple accessory parts, as regards to the material choice of the crucial core of automatic sampling, our exclusive sampling probe, as well as all other media contact disposable parts of the whole system.


Autoclavable sampling probes by bbi-biotech

Sampling probes

The bioPROBE System is based on the patented sampling technology, which we use under exclusive license of the Max-Planck-Gesellschaft. The sample material is covered with a sterile air bearing when sampled from the cultivation vessel and is afterwards transferred through the probe and a hose set to any collecting vessel. The sampling probes and the whole hose set are produced under clean atmosphere and are supplied pre-sterilized.

The probes do not need any steam supply to ensure sterile conditions, as the internal sealing of the probe’s head prevents from contamination with culture suspension as well as biofilm building. The sampling spot itself cannot be blocked by a biofilm as possible cell filtration for media measurements is done after the sampling process.
