Key Features
- Animal filtration system (option) — Long-term studies or high numbers of animals will require this filtration system to remove gaseous waste.
- Dynamic O2 cycling (upgrade) — For studies requiring cycling O2 levels for intermittent hypoxia, Coy offers a factory-installed option to ramp and cycle oxygen levels based on preset protocols in the O2 control system.
- Added capacity for animal filtration — Additional filters to enhance the filtration system and adjust for the number of animals while easing maintenance time for lab personnel.
- Heaters — Internal heaters may be added if they are needed, available for Models 30 and 60.
- Compact dehumidifier — Easy-to-maintain unit provides a way to remove moisture without using a desiccant.
- Recirculating atmosphere filtration system — System filters the box atmosphere and controls contamination through a standard HEPA filter.
SPECIFICATIONS
All O2 Control InVivo Cabinets are supplied with the following:
- Pressure relief valve
- Two sensor ports
- Circulation fan
- Gas Inlet
- Optional pullout shelf for Model 30 unit
- O2 control range from 1-100%; factory calibrated for 0-20.9% (field calibration required)
- Adjustable leveling pads
Construction
With oxygen and nitrogen gas sources connected to the O2 controller, the microprocessor controls gas purges based on sensor readings and the user-adjustable setpoint. Unlike other systems, there is no continuous purge of gas into the cabinet. This hypoxic chamber’s hermetic seal ensures that even with the controller detached, you can maintain preset O2 levels for periods of time depending on experimental conditions. This translates into less gas consumption compared to a semi sealed cabinet.
O2 Control In Vivo Cabinet Specifications
- O2 Control 0-20.9% +/- 0.1% Resolution
- CO2 Control (option) 0-20% +/- 0.1% Resolution
- NOTE: CO2 Control for in vivo units is through the Animal Filtration option which is designed to remove CO2 and other waste byproducts. However the same control mechanism can be configured for elevated (hypercapnia) studies.
- Temperature Control (option) contact Coy for details
- Humidity Control to 30 % RH or non-condensing levels

Humidity Consideration for InVivo Studies
Humidity from respiration should be controlled at least to non-condensing levels to provide an atmosphere that protects equipment and the sensors from condensation and is comfortable for the animals and users. The number of animals and the duration of hypoxic incubation will determine the appropriate humidity control solution for your study. Contact an expert at Coy Lab to discuss your options.
