Product Description
Fraser Broth w/ Supplements is a specialized microbiological medium designed for the selective enrichment of Listeria species, particularly Listeria monocytogenes. This high-quality broth from Himedia (M2002) is widely used in food safety testing, clinical diagnostics, and research laboratories. The addition of supplements enhances its selectivity, ensuring accurate detection of target pathogens while suppressing non-target bacteria.
Whether you’re a student conducting microbiology experiments or a researcher working on food safety protocols, this broth provides reliable results. Its formulation adheres to international standards, making it a trusted choice for labs across India. When you buy Fraser Broth online from eqipped, you get a product that combines convenience with scientific precision.
Key Applications
Fraser Broth w/ Supplements is primarily used for:
- Detection of Listeria in food samples
- Clinical microbiology testing
- Research on bacterial pathogens
- Quality control in food processing
The broth’s composition includes lithium chloride and other selective agents that inhibit gram-negative bacteria while allowing Listeria to proliferate. This makes it an essential tool for labs focusing on foodborne pathogen detection.
Why This Product Stands Out
What sets Fraser Broth w/ Supplements apart is its balanced formulation. Unlike generic enrichment media, this product includes specific supplements that improve recovery rates of stressed Listeria cells. This is particularly important in food testing, where pathogens may be present in low numbers or sub-lethal states.
For students and educators, this broth offers a practical way to demonstrate selective enrichment techniques in lab settings. Its consistent performance ensures reproducible results, which is critical for both learning and research applications.
Usage Guidelines
To achieve optimal results with Fraser Broth w/ Supplements:
- Reconstitute the powder as per manufacturer instructions (typically 50.5g per liter of distilled water)
- Sterilize by autoclaving at 121°C for 15 minutes
- Cool to room temperature before inoculation
- Incubate at 30-37°C for 24-48 hours
- Subculture onto selective agar for confirmation
Always follow standard microbiological practices when handling this medium. Proper aseptic technique is essential to prevent contamination and ensure accurate test results.
Storage and Shelf Life
Store the unopened powder at 2-8°C in a dry place. Once reconstituted, the broth should be used immediately or stored at 2-8°C for up to 2 weeks. For best results, prepare fresh medium for each test batch.
Safety Considerations
While Fraser Broth w/ Supplements is generally safe for lab use, always wear appropriate personal protective equipment (PPE) when handling microbiological media. Dispose of used broth according to your institution’s biohazard waste protocols.
FAQs
What is the shelf life of Fraser Broth w/ Supplements?
The unopened powder has a shelf life of 2 years when stored properly at 2-8°C. Once reconstituted, use within 2 weeks for optimal performance.
Can this broth detect all Listeria species?
While primarily designed for Listeria monocytogenes, it can support the growth of other Listeria species. However, confirmation on selective agar is recommended for species identification.
What’s the difference between Fraser Broth and other Listeria enrichment media?
Fraser Broth contains lithium chloride and other selective agents that provide better inhibition of competing flora compared to general enrichment brooks like Buffered Listeria Enrichment Broth.
Is this product suitable for student lab experiments?
Yes, it’s commonly used in educational settings to teach selective enrichment techniques. The clear protocol makes it ideal for learning environments.
How quickly can I get Fraser Broth delivered from eqipped?
