HiMedia M008S-500G MacConkey Agar, 500 g Premium Laboratory Grade

Description

Product Overview

The HiMedia M008S-500G MacConkey Agar is formulated to meet the rigorous demands of modern microbiology laboratories. This 500 g powder provides a reliable, selective medium that supports the growth of Gram‑negative organisms while inhibiting Gram‑positive contaminants, enabling clear differentiation of lactose‑fermenting and non‑fermenting bacteria. Each batch is produced under strict quality‑control protocols in HiMedia Laboratories’ state‑of‑the‑art facilities in India, ensuring uniform particle size, high purity, and consistent pH balance. The product is packaged in a sturdy, resealable container measuring 8.2 cm × 8.2 cm × 18.6 cm and weighing 0.62 kg, making it easy to store and handle. With a best‑seller rank of #8 in Lab Natural Proteins and a 4.8‑star rating from verified customers, this agar has earned a reputation for reliability and performance across academic, clinical, and industrial settings.

Usage

Designed for versatility, the MacConkey Agar is suitable for a wide range of applications, including routine bacterial identification, antimicrobial susceptibility testing, and environmental monitoring. Laboratories can use it to isolate Enterobacteriaceae from clinical specimens such as urine, stool, and wound swabs, as well as to assess water quality by detecting coliforms. The powder is easy to reconstitute: dissolve the entire 500 g package in 1 L of distilled water, autoclave at 121 °C for 15 minutes, and allow the medium to cool before pouring into sterile Petri dishes. Once solidified, the agar provides a characteristic pink to red coloration for lactose‑fermenting colonies, while non‑fermenters appear colorless or pale, facilitating rapid visual interpretation. Its stability at room temperature ensures that prepared plates can be stored for up to two weeks without loss of selectivity.

FAQ

What types of bacteria can be isolated using this MacConkey Agar?

The medium is specifically designed to isolate and differentiate members of the Enterobacteriaceae family, such as Escherichia coli, Klebsiella pneumoniae, and Salmonella spp., as well as other Gram‑negative rods. It also helps distinguish lactose‑fermenting from non‑fermenting organisms based on colony color.

How should the agar be stored after preparation?

Prepared plates should be kept at 2‑8 °C in a sealed container. Under these conditions, the medium remains stable for up to 14 days, maintaining its selective properties and preventing desiccation.

Can this agar be used for antimicrobial susceptibility testing?

Yes, MacConkey Agar can serve as a base medium for disk diffusion assays when testing the susceptibility of Gram‑negative bacteria to specific antibiotics. However, for standardized susceptibility testing, it is recommended to follow CLSI guidelines and use appropriate control strains.

Is the product compatible with automated plate‑pouring systems?

Absolutely. The powder dissolves completely to form a clear, homogenous solution that can be filtered and poured using automated dispensers. Its viscosity and gelation properties are optimized for consistent plate thickness and uniform colony distribution.

What quality certifications does HiMedia hold for this product?

HiMedia Laboratories adheres to ISO 9001 and ISO 13485 standards, and the MacConkey Agar is produced in GMP‑compliant facilities. Each batch is accompanied by a Certificate of Analysis (CoA) detailing pH, sterility, and component concentrations.
