Oxoid CampyGen™ Compact for one or two petri dishes, is a simple system for generating microaerobic conditions, that is required for culturing microaerophilic organisms, such as Campylobacter spp.


The system consists of a plastic pouch, sealing clip, and a paper gas generating sachet. The paper sachet contains ascorbic acid which reacts on contact with air to produce the microaerobic conditions for the growth of microaerophilic organisms. No catalyst is needed. The addition of water is not required. Potentially explosive hydrogen gas is not produced as with other older systems.


Ascorbic acid is the reactive component within each paper sachet.


Storage: Upon receipt store at 2-25 degrees C. Under these conditions, the CampyGen™ Compact sachets will retain their activity until the expiration date declared on the outer box and on the foil wrapped sachet. Products should not be used if there are any signs of deterioration (tears), or if the expiration date has passed. Protect from excessive heat and freezing.

The expiration date applies to the product in its intact packaging when stored as directed.

This product has the following shelf life from the date of manufacture:

365 Days: CN020C CampyGen™ Compact

For in vitro diagnostic use only. The CampyGen™ Compact paper sachet will become active on contact with air. It is therefore essential that the paper sachet is placed in the pouch and the pouch sealed immediately. The reaction of the ascorbic acid with oxygen is exothermic. However, the temperature of the CampyGen™ Compact paper sachet will not exceed 65 degrees C. On removal from the pouch after incubation, the CampyGen™ Compact paper sachet will retain a small amount of activity and become warm. The sachets should be allowed to cool to room temperature prior to sterilization and disposal with the non-hazardous laboratory waste.


Method of Use:

1. Place two inoculated media plates in the plastic pouch. Disposable plastic petri dishes should be of the vented variety to aid gas transfer between the interior and exterior of the plates. If only one plate is to be inoculated, an uninoculated plate should also be placed in the plastic pouch to prevent further activity as the volume of O2 and CO2 is critical.

2. Tear open a CampyGen™ Compact foil sachet at the tear-nick indicated. Remove the CampyGen™ Compact paper sachet from within. The sachet is activated upon exposure to air.

3. Immediately place the CampyGen™ Compact paper sachet in the plastic pouch with the plates.

Note: The CampyGen™ Compact paper sachet will become warm to the touch on exposure to air.

4. Expel excess air from the plastic pouch. Seal the plastic pouch immediately with the CampyGen™ Compact Sealing Clip (Cat. no. AN005C) or equivalent.

Note: The time taken between opening the foil sachet and sealing the plastic pouch should not exceed one minute. Extended exposure will result in loss of reactivity, and full anaerobic conditions may not be achieved in the pouch.

5. Incubate appropriately.

6. After the incubation period remove the plates or ID panel and examine for the presence of colonies or biochemical reaction. If the plates require reincubation then a fresh CampyGen™ Compact sachet must be used following steps 2-5 described above.

Note: The plates may be initially inspected through the transparent plastic pouch. If the bag is not opened, a fresh CampyGen™ Compact sachet is not required for reincubation.

7. After incubation, the exhausted CampyGen™ Compact paper sachet and plastic pouch should be sterilized and discarded with the non-hazardous laboratory waste.


It is recommended that biochemical and/or serological tests be performed on colonies from pure culture for complete identification.

It is essential that the gas generating paper sachet be placed and sealed in the jar within one minute of its removal from the outer foil sachet. Extended exposure to air will result in loss of reactivity and full microaerophilic conditions may not be achieved.


CampyGen™ Compact Sealing Clips (Cat. no. AN005C)
Plastic Pouches (Cat. no. AG020C)
Standard microbiological supplies and equipment such as loops, other culture media, slides, staining supplies, microscopes, incinerators, incubators, seal bars or clips, etc., as well as serological and biochemical reagents, are not provided.


The microaerophilic technique should be checked periodically for its ability to provide adequate conditions for the growth of microaerophilic bacteria. The following strain is recommended:

Test Organisms Reaction
Campylobacter jejuni
ATCC® 33291 Growth

CampyGen™ Compact should appear as white paper sachets individually packaged within a foil pouch.
