The FMS is a fully integrated respirometry system about the size of a shoebox. The FMS combines O2, CO2, and H2O analysis with data acquisition and subsample flow control and measurement. Whether in the lab or field, the FMS has all the versatility needed in a respirometry system without compromising accuracy.
The Sable MAVEn™ system is an integrated, compact 16-channel flow generator for small insect flow-through respirometry. Each flow is pushed through a sealed container holding a subject animal. The system automatically selects the air flows from each chamber in succession, with optional baseline interleaving, and directs that air flow to external gas analyzers.
The FLIC system provides a precise and continuous quantification of the number and duration of interactions a fly has with food. It complements conventional methods of analysis, such as the CAFE assay and tracer dye approaches, by allowing comprehensive long-term studies of new and subtle aspects of feeding behavior.
The Promethion ESA provides the unique ability to detect subtle or significant signals in the experimental operating environment that may influence research quality or confound its analysis. You will be able to see and document possible triggers for anomalous animal or cellular behaviors that typically go unexplained, including intrusive disturbances, variations in temperature or barometric pressure, and the impact of sound or light level. Information captured is integrated and synchronized with Sable’s Promethion MetaScreen, CaloScreen or SableScreen data collection and analysis software applications, allowing researchers to correlate environmental changes with study data. It can be teamed with any Promethion system for use in mouse and rat metabolic phenotyping, room calorimetry, genomics, metabolomics, cellular metabolism studies and more.
The ADX-C activity detector rests underneath the animal cage and records a range of vibrations (from shivering to running) and transforms it into an index of activity. The ADX-C will determine and measure the timing and magnitude of movement of animals ranging from large insects to squirrels. Each ADX reader manages up to 24 channels, and multiple readers can be connected to a system.
The FlowKit™ is an integrated low-noise pump and mass flow generator that accurately, quietly and economically provides large flow rates. It’s designed for applications such as large animal respirometry or air circulation in small, controlled environments. Available in 3 different models – the FK-100, FK-500 and FK-2000 – for flow ranges of 5-100, 50-500, or 400-2000 liters per minute. The FlowKit relies on modulating a powerful but quiet pump in order to create the set mass flow rate. Ultra-efficient PID (proportional integral derivative) control is used for quick response to setpoint changes and minimal variation from the setpoint. As a result, the pump works only as hard as it has to, greatly reducing pump wear, power consumption and noise. A sub-sampling pump simplifies plumbing to a respirometry system, and features both analog and serial outputs for easy connection to a data acquisition system. The FlowKit requires no temperature or barometric pressure correction because it generates mass or molar flow rates already corrected to STP. It also features a user-configurable alarm to alert users locally and remotely if a fault develops. The FlowKit is powered from 24 VDC (universal adapter supplied) and can be operated from an optional battery pack for field use.
The PP-2 dual pump system provides two reliable, variable-speed diaphragm pumps that operate on 12 VDC (adapter included). The PP-2 provides flow rates of 0-2 L/min, while the model PP-2-1 provides flow rates of 0-5 L/min. These pump systems are ideal for generating flows for respirometry and gas sampling applications. The PP-2 is quiet, operates on an uncritical source of 10 - 16 VDC (power supply included), and has two independent pumps. For most applications requiring mass flow control of up to 1 liter/minute or needle-valve-controlled flow rates up to 3 liters/minute, our PP-2 pump unit replaces conventional pumps and surpasses them in convenience and performance. Because the PP-2 pump unit includes dual variable pump drive controls that allow you to set each pump to the exact drive your application requires, wear and tear on the pumps' diaphragms is minimized. Unlike conventional pumps, the PP-2 completely isolates the pumped gas stream from ambient air. This means that you can confidently supply carbon-dioxide-scrubbed air with the PP-2, and not experience unwanted ppm-level background noise in your reference air stream. Each of the PP-2's internal pumps may be used independently. At low force, each pump can push or pull at least 500 ml/minute through a mass flow controller valve, or through several channels of a flow-control manifold. At high force, the capacity increases up to three-fold. The two pumps can also be run in parallel to increase the total available pumping force by two-fold again. The PP-2 is especially convenient for respirometry systems intended for small mammals (rat-sized and down), arthropods, amphibians or reptiles, where relatively low flow rates are the norm. A high flow version (8 liters/minute per pump) is available by special order only; contact us for information.
The DG-4 relative humidity and dewpoint controller allows versatile control of water vapor content of an air stream. It can be operated in either a locally-controlled mode, or a computer-controlled mode that allows the generation of complex water vapor ramps and steps. In relative humidity controller mode, the DG-4 reads the temperature of the area in which relative humidity control is required, via supplied thermistor probe. Using a saturated air stream as its input (saturator supplied with unit), the DG-4 then adjusts the water vapor content of the air stream to yield the precise set relative humidity. It does so by calculating the saturated water vapor pressure at the regulated air, using the measured temperature at that point. Then, it calculates the target water vapor pressure corresponding to the desired relative humidity entered by the user. Finally, it calculates the dew point corresponding to the target water vapor pressure and regulates its internal condensing unit at that temperature, using a solid-state heat pump. The result is accurate, consistent relative humidity control even in the face of fluctuating environmental temperatures. This is a unique capability of the DG-4 that is invaluable for biological experimentation, product testing, protein crystallography, and other demanding applications Alternatively, the DG-4 can be used as a dewpoint regulator (range 1 - 45 C) or as a water vapor partial pressure regulator. Air flow rates ranging from about 25 mL/minute to 5 liters/minute can be used without affecting the system's regulation efficiency. Condensed water is evacuated from the condenser by a miniature diaphragm pump at user-settable intervals. Alternatively, a simple plumbing change allows the user to remove condensate slowly and continuously with a user-supplied peristaltic pump. Operation is intuitive and flexible, allowing easy operation by a wide range of users. All adjustments and settings are permanently retained in the event of power outage. Analog and serial data outputs are standard.
