Chromogenic Coliform Agar A1 Quality – HX-Media

Chromogenic Coliform Agar A1 Quality – HX-Media

Price range: ₹6,715.00 through ₹59,505.00

Chromogenic Coliform Agar (CCA) is a selective and differential microbiological medium designed for the detection and enumeration of coliforms and Escherichia coli (E. coli) in water, food, dairy, and environmental samples.
It uses chromogenic substrates that produce distinct colony colors, enabling easy and accurate identification without additional biochemical tests.

This medium simplifies coliform testing by allowing direct differentiation:

  • E. coli → typically blue to violet colonies

  • Other coliforms → pink to red colonies

CCA is widely used due to its high specificity, clarity, and compliance with international standards.

Packing

  • Available in 100 g, 500 g, and 1 kg laboratory-grade packs.

  • Supplied in airtight, moisture-resistant containers for extended shelf life.

Product Description

Chromogenic Coliform Agar – HX-Media

Product Overview (Short)

Chromogenic Coliform Agar is a selective and differential culture medium specially formulated for the rapid detection, identification, and enumeration of coliform bacteria and Escherichia coli in various samples such as drinking water, food products, dairy items, and environmental samples.

This medium utilizes advanced chromogenic coliform agar substrate technology, which enables direct visual differentiation of microorganisms based on their enzymatic activity. Unlike conventional media, it eliminates the need for additional confirmatory biochemical tests, thereby saving time and improving laboratory efficiency.

Chromogenic Coliform Agar is widely used in quality control laboratories, water testing facilities, food and beverage industries, and environmental monitoring programs. It is particularly suitable for membrane filtration techniques, making it ideal for testing potable water and wastewater samples in compliance with international standards (such as ISO methods).

The medium is designed to deliver high sensitivity, specificity, and reproducibility, with results typically obtained within 18–24 hours of incubation. Its clear color differentiation and ease of interpretation make it a preferred choice for routine microbiological analysis and regulatory testing.

Overall, Chromogenic Coliform Agar provides a reliable, rapid, and cost-effective solution for microbial testing, ensuring accurate detection of contamination and supporting public health and safety standards.
