PreSens Precison Sensing GmbH products

The Fibox 3 and Fibox 3 trace are proven fiber optical devices for precise oxygen measurement. These oxygen meters are used in numerous applications in research and industry, like for respiration measurements or monitoring of cell culture and microbial growth - even non-invasively. They are portable due to their small outer dimensions and can easily be set up. Connected to a 2 mm polymer optical fiber the transmitters can be applied with various types of oxygen sensors, like for example sensor spots, flow-through cells or dipping probes. Optical oxygen measurement allows that the senors can be physically divided from the measurement systems, which enables to take non-invasive measurements with these devices.

The battery powered Fibox 4 is designed for easy handheld use. The robust, splash-proof housing and controls were contrived to be operated even under harsh conditions while wearing heavy gloves. The oxygen meter adapts to dry or humid environmental conditions, and has temperature as well as automatic pressure and salinity compensation. The Fibox 4 is compatible with sensor type PSt3 (detection limit 15 ppb dissolved oxygen, 0 – 100 % oxygen). With the oxygen meter’s integrated barcode reader sensor identification and calibration can be realized by performing just one scan. With the implemented sensor management system data of up to 100 sensors can be stored. Fibox 4 has 16 GB internal memory which allows prolonged computer-independent operation. The device is delivered with the PreSens Datamanagement software allowing data transfer to a PC for further analysis.

The OXY-4 mini, OXY-10 mini, OXY-4 trace and OXY-10 trace are precise multi-channel fiber optic oxygen transmitters. They are used with oxygen sensors based on a 2 mm optical fiber. A PC is connected to run the easy-to-use software. OXY-4 mini and OXY-10 mini are used for sensor coatings type PSt3 (0 - 100 % oxygen). OXY-4 trace and OXY-10 trace additionally work with the trace oxygen sensor coating type PSt6 (detection limit 1 ppb, 0 - 4.2 % oxygen).

The SFR Shake Flask Reader monitors pH, oxygen and OUR in up to 9 Erlenmeyer flasks, cultivation tubes, or T-flasks simultaneously. It fits in nearly all standard shakers. Measurement data is transferred wirelessly via Bluetooth to your PC / notebook. The corresponding ready-to-use vessels contain pre-calibrated sensor spots. The system monitors non-invasively through the transparent bottom of the container. Different types and sizes of flasks and tubes are available. Plastic, disposable flasks contain pre-calibrated oxygen and pH sensors, while re-usable glass flasks are equipped with autoclavable oxygen sensors.

The pH-1 mini is a precise fiber optic pH meter. It is used with pH sensors based on a 2 mm optical fiber. A PC is connected to run the easy-to-use software and control measurements. pH-1 mini is equipped with an analogue out and a trigger input. pH sensors type HP5 & HP8 are compatible with the pH-1 mini and are optimized for physiological solutions.

The pCO₂ mini is a precise fiber optic CO₂ meter with temperature compensation. It is used with sensors based on a 2 mm optical fiber. A PC is connected to run the user-friendly software. The pCO₂ mini is additionally equipped with an analogue output and a trigger input. The compatible CO₂ sensors of type CD1 are optimized for physiological solutions.

The non-invasive optical oxygen sensors measure the partial pressure of both dissolved and gaseous oxygen. These sensor spots are used for glassware and disposables. The sensor spots are fixed on the inner surface of the glass or transparent plastic material. The oxygen concentration can therefore be measured in a non-invasive and non-destructive manner from outside, through the wall of the vessel. Different coatings for different concentration ranges are available.
