Anaerobic Jar System NAJS-201 – Oxygen-Free Microbial Cultivation Equipment

What Is Anaerobic Jar System NAJS-201?

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.

Why Use  Anaerobic Jar System NAJS-201?

Key Benefits

• 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.

How Does Anaerobic Jar System NAJS-201 Work? 

 Anaerobic Jar System 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.

How It Works 

1. Place inoculated culture plates inside the jar

2. Add gas-generating sachet

3. Seal the chamber airtight

4. Oxygen is removed and CO₂ is generated

5. Indicator confirms anaerobic condition

6. Place jar in incubator

Outcome: Stable oxygen-free environment for microbial growth.

Applications with Outcomes

Anaerobic Jar vs Alternatives

Should You Use  Anaerobic Jar System NAJS-201?

Use  Anaerobic Jar System NAJS-201 if:

• You perform routine microbiology testing

• You need batch anaerobic incubation

• You use standard incubators

• You require cost-effective anaerobic setup

When NOT to Use This

Avoid  Anaerobic Jar System NAJS-201 if:

• You need continuous anaerobic workflow → Use chamber

• You need high automation → Use advanced systems

• You need industrial-scale production → Use bioreactors

Limitations

• Limited to batch processing

• Manual setup required

• Less precise oxygen control vs chambers

Insight: Best for labs, not large-scale production.

Alternative Equipment

• Anaerobic chambers → continuous operation

• CO₂ incubators → non-anaerobic cell culture

• Microaerophilic systems → low oxygen studies
