Nutrient Agar, 20 mL, 100 × 15 mm Plate, 10/Pk

This product provides 20mL of Nutrient Agar in a pre-poured, sterile petri dish. This is the fundamental, general-purpose medium used in microbiology for the cultivation of non-fastidious microorganisms (bacteria that do not require special supplements to grow).

The "Baseline" Standard: Nutrient Agar is the "vanilla" medium of the lab—simple, effective, and neutral.

1. The Formulation: It consists of Beef Extract and Peptone. These provide the basic nitrogen, carbon, vitamins, and amino acids required for the growth of common bacteria like E. coli, Staphylococcus, and Bacillus.

2. Non-Selective Nature: Because it contains no inhibitors (like bile salts or antibiotics) and no complex enrichments (like blood), it allows a wide variety of environmental and clinical bacteria to grow freely.

The Pigment Canvas: One of the distinct advantages of Nutrient Agar is its clarity and lack of dye. Because the medium is naturally a pale amber color:

• True Color Visualization: It is excellent for observing the natural pigmentation of bacterial colonies. The golden yellow of Staphylococcus aureus, the red of Serratia marcescens, or the lemon yellow of Micrococcus luteus show up clearly without interference from pH indicators found in selective plates.

Common Applications:

• Education: The standard medium for teaching basic bacteriology techniques in schools and universities.

• Water & Sewage: Used for the enumeration of organisms in water, sewage, and dairy products (Standard Plate Count).

• Subculturing: Maintaining stock cultures where specific differential properties are not required.

• Purity Checking: A neutral ground to verify if a culture is pure before performing biochemical tests.

Key Features:

• General Purpose: Supports a broad spectrum of non-fastidious bacteria.

• High Clarity: Ideal for observing natural colony morphology and pigmentation.

• Standard Fill: 20mL volume supports healthy colony development.

• Economical: A cost-effective solution for routine maintenance and teaching.

• Format: Sterile pre-poured agar plates (10-pack).
