Nutrient Agar Slant 4mL Tube, 10/Pk

Nutrient Agar Slants are general-purpose, non-selective culture media used for the cultivation, maintenance, and storage of a wide variety of non-fastidious bacteria. Each tube contains 4mL of agar that has been allowed to solidify at an angle (a "slant").

Why use a slant? The slanted surface maximizes the available surface area for bacterial growth within the compact space of a test tube. This format is ideal for:

1. Stock Cultures: Slants are the standard method for maintaining pure cultures over longer periods because the screw-cap minimizes evaporation and contamination risk compared to petri dishes.

2. Transport: The contained, sealed tube is safer and more durable for shipping biological samples than a plate.

3. Biochemical Screening: Often used as a base for observing pigment production (e.g., the green pigment of Pseudomonas aeruginosa) or for harvesting biomass for further testing.

The medium consists of Beef Extract and Peptone, providing the basic nitrogen, carbon, vitamins, and amino acids required for the growth of common organisms like E. coli, Staphylococcus, and Bacillus.

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

• Culture Maintenance: Ideal format for storing stock cultures in refrigerators.

• Space Efficient: Slanted design increases surface area without increasing tube volume.

• Pigment Visualization: Clear, neutral background allows for easy observation of bacterial pigments.

• Secure: Screw-cap tube prevents dehydration and contamination during storage or transport.

• Format: Sterile 4mL agar slants in 10-pack.
