OXYGEN-SENSITIVE CAP OSC-PSt3

To measure oxygen ingress in non-transparent bottles, the Oxygen-Sensitive Cap OSC-PSt3 must be placed on the transparent closure—the oxygen-sensitive cap—tailored to the respective PET bottle. Three seals ensure gas-tight closure. A safety screw adapted to the bottle thread is used to secure the closure.

OXYGEN EXCHANGE CAP OEC-PSt7-YAU

The Oxygen Exchange Cap is made of stainless steel and includes an integrated PSt7 sensor. The sensor has a measurement range of 0–100% O₂ and a detection limit of 0.03% O₂. It is suitable for steam sterilization and cleaning in place. The OEC-PSt7-YAU is available in different versions: USP Class VI compliant (YOP) for bioprocess monitoring, food-safe (CAF), or with a hydrophobic Teflon coating (PTFE) for use in aggressive environments. The OEC can be screwed onto the top of the OXYPro® WR / WRM fitting. Sensor replacement is easy, as calibration can be performed quickly via barcode scanning.

HANDHELD USB-QR BARCODE SCANNER

This handheld scanner connects easily to your PC via USB and is compatible with PreSens Measuring Studio 2, PreSens Device Configurator, and EOM-STS Pro software. Connect a PreSens device to your computer and software to calibrate your sensors with a quick barcode scan. The software transfers the new calibration data to the device. The handheld USB-QR barcode scanner significantly speeds up the calibration process, eliminating the need for manual data entry and enabling rapid calibration of multiple sensors.

MANUAL MICROMANIPULATOR MM33

The manual micromanipulator MM33 offers high-resolution control when working with PreSens microsensors. The system allows vibration-free positioning of the microsensor in three axes with micrometer reading accuracy. MM33 is equipped with a tilting platform—when mounted on the Heavy Stand, it can be adjusted and used in any orientation. It can also be fitted with the Safe-Insert accessory, allowing the retracted microsensor in its steel needle to be safely inserted into the area of interest. The sensor tip can then be carefully extended with precise control, minimizing the risk of fiber breakage.
