Product Description
When it comes to detecting Salmonella in food or clinical samples, precision matters. The Modified Rappaport Vassiliadis HiVeg® Medium (MV1137) is a specialized, plant-based formulation designed to enhance the recovery of Salmonella while inhibiting competing flora. Unlike traditional RV mediums, this HiVeg® variant replaces animal-derived components with high-quality plant peptones, making it ideal for laboratories prioritizing ethical and consistent results.
This medium is widely used in microbiology labs, research institutes, and food testing facilities across India. Its selective properties ensure that even low levels of Salmonella can be isolated efficiently, reducing false negatives. Whether you’re a student working on a project, a researcher validating protocols, or a quality control professional in the food industry, this medium delivers reliable performance every time.
At eqipped, we understand the importance of sourcing lab supplies that meet both technical and ethical standards. That’s why we offer this lab-grade RV medium at competitive prices, ensuring you get the best value without compromising on quality. Need a trusted supplier for Modified RV medium?

Why This Medium Stands Out
The Modified RV HiVeg® Medium isn’t just another selective medium—it’s engineered for better sensitivity. The inclusion of magnesium chloride and malachite green creates an environment where Salmonella can thrive while suppressing gram-positive bacteria and coliforms. This is particularly useful in samples with mixed microbial populations, such as raw meat, dairy, or environmental swabs.
For educators, this medium serves as an excellent tool for teaching microbial isolation techniques. Its clear differentiation of Salmonella colonies (typically appearing as colorless or pale) makes it easier for students to interpret results accurately. Researchers, on the other hand, appreciate its consistency, which is critical for reproducible experiments.
If you’re looking to buy Rappaport Vassiliadis medium online, eqipped ensures you receive a product that’s been tested for performance and shelf stability. Our 500 gm pack size is perfect for labs with moderate to high throughput, reducing the need for frequent reorders.
Applications in Real-World Settings
From food safety audits to clinical diagnostics, this medium finds applications in:
- Food and beverage industry: Testing raw materials, processed foods, and water samples for Salmonella contamination.
- Clinical microbiology: Isolating Salmonella from stool, blood, or urine samples in diagnostic labs.
- Environmental monitoring: Detecting Salmonella in wastewater, soil, or surface swabs.
- Academic research: Used in studies involving bacterial pathogenesis, antibiotic resistance, or microbial ecology.
Given its versatility, it’s no surprise that labs across India rely on this medium. Looking for a modified RV medium supplier that guarantees authenticity? eqipped sources directly from Himedia, ensuring you get genuine products every time.
Handling and Storage Guidelines
To maintain the medium’s efficacy, follow these best practices:
- Store the powder in a cool, dry place away from direct sunlight. The recommended storage temperature is 2–8°C once opened.
- Reconstitute the medium as per the manufacturer’s instructions (typically 22.5 gm per liter of distilled water).
- Sterilize by autoclaving at 121°C for 15 minutes. Avoid overheating, as it may degrade selective agents.
- Prepared plates should be used within 7 days if stored at 2–8°C.
Always wear appropriate PPE (gloves, lab coat, and goggles) when handling microbial media. While this medium is non-hazardous, good laboratory practices should be followed to prevent contamination.
Common Challenges and Solutions
Even with a high-quality medium like this, users sometimes face issues. Here’s how to troubleshoot:
- Problem: No growth observed.
Solution: Check the inoculation technique, incubation conditions (42°C for 24–48 hours), and medium preparation. Ensure the sample wasn’t over-diluted. - Problem: Overgrowth of non-Salmonella bacteria.
Solution: Verify the medium’s expiry date and storage conditions. Contaminated water or glassware can introduce competing microbes. - Problem: Weak or delayed Salmonella growth.
Solution: The sample may contain stressed cells. Pre-enrichment in a non-selective broth (like buffered peptone water) can help revive injured bacteria.
If you’re new to using this medium, consider running parallel tests with a known Salmonella strain to validate your protocol.

FAQs
What is the shelf life of Modified RV HiVeg® Medium?
The powder has a shelf life of 3 years from the date of manufacture when stored properly. Once reconstituted, use the medium within 7 days if refrigerated.
Can this medium detect all Salmonella serotypes?
While highly effective for most Salmonella spp., some serotypes like S. Typhi may require additional confirmation tests. Always follow standard microbiological protocols.
Is this medium suitable for vegan or animal-free labs?
Yes! The HiVeg® formulation replaces animal peptones with plant-derived alternatives, making it ideal for labs with ethical sourcing requirements.
How does this compare to traditional RV medium?
The modified version offers better recovery rates for stressed Salmonella cells and reduces false positives by improving selectivity against competitors like Proteus spp.
What’s the best way to dispose of used plates?
Autoclave used plates at 121°C for 30 minutes before disposal. Follow your lab’s biohazard waste protocols to ensure safety.
