DSI Plethysmography Chambers
DSI offers helmets, chambers, accessories and replacement parts to support research with various species. No other supplier offers the breadth of plethysmography products and the ability to integrate other technologies. Accurate, reliable data and service that is second-to-none make DSI the obvious choice. Contact DSI for more information on all of your chamber needs.
DSI’s Plethysmography Chambers are ideal for respiratory rate and tidal volume assessments. Alternatively, with the combination of telemetry and hardwired signals, the system can be used to acquire cardiovascular and respiratory endpoints in a single study.
Pair plethysmography chambers with The Bias Flow Generator to prevent the buildup of carbon dioxide in the respiratory apparatuses. The bias flow generator provides a source of fresh air and helps maintain temperature and humidity levels within the chambers.
Mouse, Rat and Guinea Pig Unrestrained Whole Body Plethysmography
DSI’s Unrestrained Whole Body Plethysmograph chambers enable researchers to monitor physiologic endpoints such as Breaths-per-Minute (BPM), Tidal Volume, Minute Volume, Inspiratory time, Expiratory time, Pause and PenH from unrestrained animals.
Features:
- Designed to reduce environmental ambient noise produced by changes in room air flows.
- Top loading for easy placement of test subjects.
- Accommodates a wide range of pressure transducers.
- Stainless steel grid floor provides improved animal hygiene.
- Easy to clean aerosolization port.
- Single screen pneumotachograph eliminates the need to overlap multiple screens while providing optimal resistance.
DSI also offers a line of replacement accessories providing customers the ability to replace contaminated, lost or damaged chamber parts and extend the operational life of the DSI Unrestrained Whole Body Plethysmograph Chambers.
Rat Restrained Plethysmograph
Advantages over the competition include:
- Improved latching mechanism reduces animal disturbances.
- Better sealing neck material available in pre-cut diameters for use with varying sized rats.
- Enhanced pusher mechanism provides feedback to user regarding pressure placed on rat as well as allows for quicker animal load times.
- Single screen eliminates the need to overlap multiple screens, providing optimal resistance.
- Plethysmography chamber sold in three main parts allowing customers to order only sections of the chamber needing to be replaced.
Mouse Restrained Plethysmograph
DSI’s new mouse plethysmograph is ideal for mouse respiratory studies:
- Designed to accommodate the Validyne pressure transducer
- Unlike competing products, DSI’s chamber only contains a single screen in the pneumotach, making its placement worry-free!
- And don’t forget that DSI is the only company that can digitally synchronize your hardwired signals with telemetric signals!
