Anaerobic Jar System NAJS-201 is a laboratory device that creates oxygen-free conditions using gas-generating systems inside a sealed chamber. It is used to cultivate anaerobic microorganisms for microbiology testing, research, and quality control in pharmaceutical, clinical, and food safety laboratories.
Anaerobic Jar System NAJS-201 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 low oxygen levels
Outcome: Enables accurate microbial cultivation and testing.
Ensures oxygen-free microbial environment
Improves accuracy of microbiological testing
Supports GMP and lab compliance workflows
Compatible with standard incubators
Enables batch processing of multiple samples
Result: Accurate and reproducible laboratory outcomes.
NAJS-201 removes oxygen using gas-generating sachets inside a sealed jar. The system releases carbon dioxide and absorbs oxygen, while indicator strips confirm anaerobic conditions during incubation.
Place inoculated culture plates inside the jar
Add gas-generating sachet
Seal the chamber airtight
Oxygen is removed and CO₂ is generated
Indicator confirms anaerobic condition
Place jar in incubator
Outcome: Stable oxygen-free environment for microbial growth.
Capacity: Up to 12 Petri dishes
Material: Polycarbonate / Stainless Steel
Sealing: Clamp-based airtight lid
Gas System: Chemical sachets / gas packs
Indicator: Included
Temperature: Incubator compatible
Weight: 3–5 kg
Use this system if:
You perform routine microbiology testing
You need batch anaerobic incubation
You use standard incubators
You require cost-effective anaerobic setup
Avoid NAJS-201 if:
You need continuous anaerobic workflow → Use chamber
You need high automation → Use advanced systems
You need industrial-scale production → Use bioreactors
Limited to batch processing
Manual setup required
Less precise oxygen control vs chambers
Insight: Best for labs, not large-scale production.
Anaerobic chambers → continuous operation
CO₂ incubators → non-anaerobic cell culture
Microaerophilic systems → low oxygen studies
It is used to grow microorganisms that require oxygen-free conditions for accurate microbiological testing.
