Anaerobic Jar System NAJS-202 is a sealed incubation system designed to remove oxygen and maintain anaerobic conditions for microbial growth.
Anaerobic microorganisms → cannot survive in oxygen
Microaerophilic organisms → require reduced oxygen
Outcome: Enables controlled microbial cultivation and accurate testing.
Creates stable oxygen-free environments
Improves accuracy of microbiological results
Supports GMP and ISO laboratory workflows
Compatible with standard incubators
Allows batch processing of multiple samples
Result: Consistent and reproducible microbial analysis.
Anaerobic Jar System NAJS-202 uses gas-generating sachets to absorb oxygen and release carbon dioxide inside a sealed jar. Indicator strips confirm anaerobic conditions while the system incubates microbial cultures.
Place inoculated plates inside the jar
Insert gas-generating sachet
Seal the chamber airtight
Oxygen is removed and CO₂ is generated
Indicator confirms anaerobic condition
Place jar in incubator
Outcome: Controlled anaerobic environment for microbial growth.
Capacity: 12–14 Petri dishes
Material: Polycarbonate / Stainless Steel
Sealing: Clamp-based airtight lid
Gas System: Chemical sachets / gas packs
Indicator: Included
Temperature: Incubator compatible
Weight: 4–6 kg
Use Anaerobic Jar System NAJS-202 if:
You need batch anaerobic cultivation
You perform routine microbiology testing
You use incubator-based workflows
You require cost-effective anaerobic setup
Avoid Anaerobic Jar System NAJS-202 if:
You need continuous anaerobic processing → Use chamber
You need automation and precision control → Use advanced systems
You need industrial-scale microbial production → Use bioreactors
Limited to batch processing
Manual setup required
Less precise oxygen control than anaerobic chambers
Insight: Ideal for labs, not large-scale production.
Anaerobic chambers → continuous operation
CO₂ incubators → non-anaerobic applications
Microaerophilic systems → reduced oxygen studies
It is used to cultivate microorganisms that require oxygen-free environments for accurate microbiological testing.
Typically 30 minutes to a few hours, depending on the gas system used.

Guide to Anaerobic Cultivation
Anaerobic Jar System NAJS-202 accommodates one stack of up to 18 Petri dishes (90–100 mm) and establishes anaerobic conditions within 2 to 4 hours using gas generation systems. Constructed from transparent, impact-resistant PMMA with an O-ring sealing mechanism and stainless steel clamp, it ensures accurate airtight performance and allows continuous visual monitoring of cultures.
