Product Description
MacConkey Agar is a widely used microbiological medium designed for the selective isolation and differentiation of Gram-negative bacteria, particularly those capable of lactose fermentation. This formulation includes 0.15% bile salts, crystal violet (C.V.), and sodium chloride (NaCl), making it highly effective for identifying coliforms and other enteric pathogens.
Whether you’re a student, researcher, or educator, this agar provides reliable results for routine microbiology testing. The addition of bile salts inhibits the growth of Gram-positive bacteria, while the neutral red indicator helps distinguish lactose-fermenting colonies (pink/red) from non-fermenters (colorless).
At eqipped, we ensure this product meets USP standards for consistent performance in labs across India. Ideal for educational institutions, clinical labs, and research facilities, this agar supports accurate bacterial identification and antibiotic susceptibility testing.

Key Applications
This agar is essential for:
- Isolating and identifying enteric bacteria like E. coli and Salmonella.
- Differentiating lactose-fermenting and non-fermenting Gram-negative bacteria.
- Routine water and food safety testing.
- Educational microbiology experiments.
Why This Product Stands Out
Unlike generic alternatives, this MacConkey Agar is formulated with precise bile salt concentrations to ensure optimal selectivity. The inclusion of crystal violet further enhances inhibition of unwanted bacterial growth, while the USP-grade quality guarantees reproducibility in your experiments.
For researchers and educators, this means fewer false positives and clearer results. Students benefit from a medium that aligns with standard microbiology protocols, making it easier to learn and apply techniques.
Usage Guidelines
To prepare the medium, suspend 52 grams of the powder in 1 liter of distilled water. Heat to boiling to dissolve completely, then sterilize by autoclaving at 121°C for 15 minutes. Cool to 45-50°C before pouring into sterile Petri dishes.
Store the prepared medium at 2-8°C and use within the recommended shelf life for best results. Always follow standard microbiological practices when handling and disposing of cultures.
Safety Note
This product is for laboratory use only. Handle with care, wearing appropriate PPE (gloves, lab coat, and eye protection). Avoid inhalation or ingestion. Dispose of used cultures according to biohazard waste protocols.
FAQs
What is MacConkey Agar used for?
It’s primarily used to isolate and differentiate Gram-negative bacteria, especially lactose-fermenting species like E. coli from non-fermenters like Salmonella.
How does bile salt help in this agar?
Bile salts inhibit the growth of Gram-positive bacteria, allowing selective isolation of Gram-negative organisms.
Can I buy MacConkey Agar online in India?
Yes, eqipped offers convenient online purchasing with fast delivery across India.
What’s the shelf life of this product?
The powder has a shelf life of 24 months when stored in a cool, dry place. Prepared plates should be used within 4 weeks.
Is this suitable for student lab experiments?
Absolutely. Its USP-grade quality ensures reliable results for educational microbiology courses.
