Anaerobic Jar System NAJS-203 is an oxygen-free cultivation system designed to grow obligate anaerobes and microaerophilic organisms under controlled laboratory conditions. It supports microbial analysis, contamination testing, and reproducible experimentation.
This system is used to culture oxygen-sensitive microorganisms in sealed environments.
Clinical microbiology → Accurate pathogen detection
Pharmaceutical QC → Regulatory-compliant microbial validation
Food safety testing → Accurate contamination analysis
Environmental research → Controlled microbial studies
The system operates by placing inoculated culture plates inside an airtight jar along with a gas-generating sachet.
Oxygen is absorbed inside the chamber
Carbon dioxide is released to create anaerobic conditions
Indicator strips confirm oxygen removal
The jar is incubated for microbial growth
Result: Stable, reproducible anaerobic environment
Ensures oxygen-free microbial cultivation
Supports reproducible laboratory results
Compatible with standard incubators
Easy to operate with minimal setup
Suitable for routine and research workflows
You need anaerobic microbial cultivation
Batch processing of samples is required
You want a compact, incubator-compatible system
Laboratory testing requires controlled oxygen-free conditions
Continuous anaerobic workflow is required → Use anaerobic chamber
Large-scale production is needed → Use bioreactor
Automated environmental control is required → Use advanced systems
Anaerobic Jar → Best for batch testing and small labs
Anaerobic Chamber → Continuous oxygen-free operations
CO₂ Incubator → Not fully anaerobic (only controlled CO₂)

1. What is an anaerobic jar system used for?
It is used to cultivate oxygen-sensitive microorganisms under controlled anaerobic conditions.
2. How does it remove oxygen?
Gas-generating sachets absorb oxygen and release CO₂ inside a sealed chamber.
3. How long can anaerobic conditions last?
Typically up to 72 hours depending on the method used.
4. Can it be used in an incubator?
Yes, it is fully compatible with standard laboratory incubators.
5. What organisms require anaerobic conditions?
Obligate anaerobes, microaerophiles, and some facultative anaerobes.
6. Is it reusable?
Yes, the jar is reusable, while gas sachets and indicators are consumables.
