MEASUREMENT SOLUTIONS FOR BIO SCIENCES

This system includes a swim tunnel and everything needed for automated water velocity control and calibration.

Applications include Ucrit tests, swimming behavior, forced exercise, swimming kinematics, and other experiments requiring accurate and computerized control of activity level/swimming speed.

Monitor, log and control oxygen and temperature in up to 24 independent tanks from a single computer with wireless Bluetooth communication. Fiber optic oxygen sensing technology in combination with a high-precision temperature and real-time compensation, offers unbeaten accuracy and stability of oxygen data as well as zero sensor maintenance. The user-friendly WitroxCTRL software makes it easy to calibrate, change measuring units, and set up automated protocols for changes in oxygen and temperature in steps or in a sinusoid manner (e.g. to mimic natural fluctuations like diurnal changes in oxygen saturation or temperature). The systems comes with all the necessary hardware and software, except for a Windows PC.

This system measures individual respiration in real-time in tiny organisms like Zebrafish embryos, Daphnia, fish/invert eggs or larvae, Drosophila etc., based on a 24-channel optical fluorescence oxygen reading device. Individual organism are placed inside gas-tight 80-1,700 µl glass chambers on a 24-well microplate footprint for real-time oxygen consumption rate measurements. Each chamber is fitted with a non-invasive and re-usable oxygen sensor spot that can be re-calibrated and sterilized for multiple trials. The microplate and reader is placed inside an incubator for temperature control, or use an optional flow-through water bath and refrigerated circulator. A soft silicone gasket with an optional line (e.g. parafilm) is placed on top of the microplate to seal the 24 chambers in one go. For high-throughput the system can be upgraded to include 10 readers/plates, i.e., for measuring respiration in 240 organisms simultaneously.
