Product Description
MacConkey Agar is a widely used selective and differential medium in microbiology labs. Designed to isolate and differentiate Gram-negative bacteria, it contains bile salts and crystal violet to inhibit Gram-positive bacteria while allowing lactose-fermenting colonies to appear pink/red. This makes it indispensable for identifying enteric pathogens like E. coli and Klebsiella.
Whether you’re a student, researcher, or educator, this medium ensures reliable results for experiments, quality control, or educational demonstrations. The 5 × 250 ml pack size offers convenience for frequent use, reducing the need for repeated purchases.

MacConkey Agar is particularly useful in clinical and environmental microbiology. Its ability to distinguish lactose fermenters from non-fermenters helps in preliminary identification of bacterial species. For example, E. coli typically produces pink colonies, while Salmonella appears colorless. This visual differentiation simplifies workflows in diagnostic and research settings.
When preparing the medium, follow standard protocols to ensure optimal performance. Autoclave the solution at 121°C for 15 minutes, then pour into sterile Petri dishes. Store the prepared plates at 2–8°C to maintain efficacy.
