Qubit Systems has been designing and building equipment for aquatic biology for almost 25 years. We provide systems for a wide variety of applications, from monitoring photosynthesis in chloroplast and algal suspensions to measuring O2 consumption and CO2 production in fish. All of our sensors use the same intuitive data acquisition and control software, so you spend more time doing science and less time configuring equipment.
Q-Box Aqua from $5000 US
The Q-Box AQUA Aquatic Respirometry Package measures metabolic rate using automated intermittent flow respirometry. The standard format is for larger fish, and a Mini-Aqua version has chambers of 9.0 mL and 1.5 mL for smaller fish and invertebrates. An O2 optode is used for measuring dissolved O2 concentration, and the package includes a temperature probe, salinity sensor and all necessary hardware and software.
We have been using the Q-Box AQUA for a year and have been impressed with the quality and versatility of the system. The technicians at Qubit are outstanding .

OX1LP from $3500 US
The OX1LP Dissolved Oxygen Package comprises a water-jacketed cuvette incorporating a high resolution polarographic O2 sensor. It may be used with plants, animals, cells and organelles (mitochondria and chloroplasts), and to monitor chemical and biochemical reactions that produce or consume O2. Cuvettes are available from 1.0 mL to 50 mL, each variable to 20% of maximum volume and fittings onto the same electrode base and stirrer unit.
The Qubit OX1LP provides the best signal to noise ratio I ever had with micro-chambers.

Dissolved CO2 Analysis from $5800
Qubit's Dissolved CO2 Analysis Systems are available in standard and rapid response versions including a precision NDIR CO2 analyzer with optional ranges from ppm levels to 100% CO2.
Qubit's Aquatic Control Systems may be used in either freshwater or salt water to regulate DO2, DCO2, pH, temperature, salinity and turbidity in up to 4 different tanks, independently. Data are recorded and displayed using software with acquisition rates from milliseconds to hours.
