Product catalog summary

Introduction
The Shake Flask Reader (SFR) by PreSens is an online measurement device designed for monitoring dissolved oxygen (DO) and pH in shake flasks. It supports up to 9 flasks simultaneously and is compatible with Kuhner incubator shakers, facilitating microbial cultivation and cell culture.

Specifications

Oxygen Sensor: Range 0-100%, Accuracy ±0.01% O2 at 0.21% O2, Drift <0.015% O2 per day, Temperature range up to 50°C.
pH Sensor: Range pH 5.5 - 8.5, Accuracy ±0.05 pH at pH 7, Drift <0.005 pH per day, Temperature range up to 50°C.
Shake Flask Reader: Suitable for all Kuhner Shakers, Temperature range 5°C - 50°C, Flask positions vary by size (up to 9 for 125mL to 5 for 2000mL).

Integration and Compatibility
The SFR integrates seamlessly with Kuhner incubator shakers and is mounted on any Kuhner universal tray. It uses non-invasive sensor spots fixed to the flask bottom for measurement.

Measurement Method
The SFR excites dyes in sensor spots, and the resulting luminescence is converted to pH and DO measurements. These are checked against calibration data for accuracy.

Software Features
The SFRS software provides real-time data display, logging, and export capabilities. It supports wireless connection to a PC and allows comparison with historical data.
