Aquatic Biology

Swim Tunnels Swim tunnel respirometers in unique design, developed through more than 10 years of research and experience from labs around the world. For use in applications such as measuring the oxygen consumption of swimming fish, exercise physiology and biomechanics, and kinematics. A variety of sizes and shapes are available.
Aqueous Phase Oxygen Regulation Turn-key system for monitoring and control of oxygen in aqueous phase systems for biological or chemical investigations. The system compares preset oxygen saturation (or concentration) with measured values. For example if the oxygen saturation is higher than the setpoint value, the relay activates a solenoid valve to open for injection of compressed nitrogen. The solenoid valve remains open until the setpoint is reached.
Water Temperature Regulation Turn-key system for monitoring and regulating water temperature in fish tanks, aquaria, respirometers etc. The system compares preset temperature with measured values. For example, if the temperature is higher than the setpoint the relay activates a submersible pump to empty cold water into the reservoir. The pump remains active until the setpoint is reached.
Automated Aquatic Respirometry Systems for measuring oxygen consumption rates of aquatic organisms, i.e. fish or BOD, and at the same time controlling experimental pumps, water temperature and oxygen saturation automatically. The systems includes user-friendly Windows software and USB instrument for an easy and effortless approach to intermittent flow respirometry.
Aquatic Respirometers Qubit's custom sized acrylic respirometer chambers for intermittent flow respirometry. Measure oxygen consumption on aquatic breathers (e.g. fish) ranging in size from a few grams and up to several kilograms. Each respirometer has 2 inlet ports and 2 outlet ports for attaching to submersible pumps.
Polarographic and Galvanic Electrodes A variety of polarographic electrodes (O2 and CO2), miniature galvanic oxygen electrodes, flow through cuvettes and glass respirometer chambers for measuring O2 concentration in aqueous samples. Choose the electrode that best suits your application and use our data acquisition systems or we can modify the electrode to fit with your system!
Submersible Pumps The submersible pumps are ideal for use in measurements of aquatic respirometry to provide water flow through tubing and respirometers. The pumps can be used as either flush pumps or as recirculating pumps and should be chosen based primarily upon flow rate characteristics.
Video Tracking Software Qubit Systems has a variety of Video Tracking Software packages available for recording and analyzing objects in experimental designs. The DV1 Software allows the user to record and perform live tracking on single objects in the viewing frame, based on contrast. The DV4 Software allows the user to record and perform live tracking on 1, 2 or 4 objects in the viewing frame, based on contrast.The DV5 software is a revolutionary new program designed to track more than 1 object at a time, even if the objects overlap. This software also includes several calculations such as velocity, acceleration, distance traveled, time in zones and time spent in motion. All software packages include DEMO versions which are comparable to the full version but do not allow to saving data.
AQUARESP Aquatic Respirometry Package The Aquatic Respirometry Package measures changes in oxygen production, transpiration or respiration in aquatic plants and animals. The package is a single channel, open flow, intermittent respirometry system based on a research-grade oxygen sensor and 15-bit data acquisition via USB. The PC software provides accurate and stable measurements of oxygen production or consumption rates every 3-5 minutes in a controlled environment.
OX1LP Dissolved Oxygen Package Qubit Systems's package for measuring dissolved O2 has features included in no other polarographic O2 monitoring system. The O2 electrode within the water-jacketed cuvette may be used for measurements of O2 consumption (or production) by biological samples or enzymatic reactions. Various chamber volumes available from 0.2 mL to 50 mL.
