Kuhner shaker

Integration into Kuhner incubator shakers

The SFR fits in all Kuhner incubator shakers. It is screwed directly on to any Kuhner universal tray (EU, EXU, FU).

The specialization provides monitoring of oxygen and pH in up to 9 shake flasks simultaneously. The corresponding ready-to-use flasks contain pre-calibrated sensor spots. The system monitors non-invasively through the transparent bottom of the flask. Different types and sizes of flasks are available. Plastic flasks contain pre-calibrated oxygen and pH sensors. They are ready-to-use for one cultivation. Glass flasks are equipped with autoclavable oxygen sensors.
