Product Description
When it comes to detecting Salmonella in food, water, or clinical samples, precision matters. Rappaport Vassiliadis Soya Broth (RV Broth) is a specialized culture medium designed to selectively enrich Salmonella species while inhibiting competing microorganisms. This granulated formulation from Himedia (GM1491) ensures consistency and ease of preparation, making it a trusted choice for microbiology labs across India.
Whether you’re a student conducting research, an educator demonstrating microbial techniques, or a professional running diagnostic tests, this broth provides the reliability you need. The soya-based composition enhances the recovery of stressed Salmonella cells, improving detection accuracy in challenging samples.
Why is this broth essential for your lab? Salmonella contamination is a critical concern in food safety and public health. Using a high-quality medium like RV Broth ensures that your results are both sensitive and specific, reducing false negatives that could lead to undetected outbreaks. The granulated form dissolves quickly, saving time without compromising performance.
At eqipped, we understand the importance of dependable lab supplies. That’s why we source products like this from reputable brands such as Himedia, ensuring you get media that meets international standards. Whether you’re setting up a new lab or restocking, this 500 gm pack offers great value for frequent use.

How to Use Rappaport Vassiliadis Soya Broth
Preparing and using RV Broth correctly is key to obtaining reliable results. Follow these steps for optimal performance:
- Reconstitution: Dissolve 25 grams of the granulated broth in 1 liter of distilled water. Stir well to ensure complete dissolution.
- Sterilization: Autoclave the medium at 121°C for 15 minutes. Allow it to cool to room temperature before use.
- Inoculation: Aseptically transfer the test sample (e.g., food homogenate or clinical specimen) into the broth. The recommended ratio is typically 1:10 (sample to broth).
- Incubation: Incubate at 41.5°C ± 0.5°C for 18–24 hours. This temperature selectively favors Salmonella growth while inhibiting most other bacteria.
- Subculturing: After incubation, streak a loopful of the broth onto selective agar plates (e.g., XLD or Bismuth Sulfite Agar) for further isolation and confirmation.
For best results, always follow your lab’s standard operating procedures (SOPs) and refer to the manufacturer’s guidelines provided with the product.
Applications of RV Broth in Microbiology
This versatile medium is widely used in various settings, including:
- Food Safety Testing: Essential for detecting Salmonella in dairy, meat, poultry, and processed foods as part of quality control.
- Water Analysis: Used to monitor water sources for contamination, especially in public health and environmental labs.
- Clinical Diagnostics: Helps identify Salmonella in stool samples or other clinical specimens from patients with suspected infections.
- Research and Education: A staple in academic labs for teaching microbial enrichment techniques and food microbiology.
Its selective properties make it indispensable where accurate Salmonella detection is non-negotiable.
Why This Broth Stands Out
Not all culture media are created equal. Here’s what sets this RV Broth apart:
- High Selectivity: The combination of soya peptone, magnesium chloride, and malachite green effectively suppresses non-Salmonella bacteria.
- Recovery of Stressed Cells: The formulation helps revive injured Salmonella cells, improving detection rates.
- Consistent Performance: Granulated media ensure uniform composition batch after batch, reducing variability in results.
- Ease of Use: Quick dissolution and clear instructions make it user-friendly for labs of all sizes.
When you buy Rappaport Vassiliadis Soya Broth online from eqipped, you’re investing in a product that delivers precision when it matters most.
Storage and Handling
To maintain the integrity of your RV Broth:
- Store the unopened pouch in a cool, dry place away from direct sunlight.
- Once reconstituted, store the broth at 2–8°C and use within the recommended shelf life.
- Avoid contamination by using sterile techniques during preparation and handling.
Always check the expiry date on the packaging before use.
Safety Considerations
While RV Broth is generally safe for lab use, follow standard microbiological safety practices:
- Wear appropriate personal protective equipment (PPE) like gloves and lab coats.
- Handle all microbial cultures in a biosafety cabinet when necessary.
- Dispose of used media and contaminated materials according to your lab’s biohazard waste protocols.
FAQs
What is Rappaport Vassiliadis Soya Broth used for?
It is a selective enrichment broth used primarily for the isolation and detection of Salmonella species from food, water, and clinical samples. The medium inhibits competing bacteria while promoting Salmonella growth.
How do I prepare RV Broth from the granulated form?
Dissolve 25 grams of the granules in 1 liter of distilled water, sterilize by autoclaving at 121°C for 15 minutes, and cool before use. Follow the incubation guidelines for your specific application.
Can I use this broth for detecting other pathogens?
No, RV Broth is specifically formulated for Salmonella. For other pathogens like E. coli or Listeria, use media designed for those organisms, such as MacConkey Broth or Listeria Enrichment Broth.
What is the shelf life of this product?
The unopened granulated broth typically has a shelf life of 2–3 years when stored properly. Always check the expiry date on the packaging before use.
