When Are Agar Slants Used?

Agar slants can be used to culture bacterial cells for identification. Attempting to identify bacteria from a large sample is difficult because bacteria are small and can be difficult to find.

What are agar slants used for?

To make it a slant tube the agar is allowed to cool with the tube laying at an angle, resulting in a large surface area for spreading a culture. Agar slants are used for storing pure cultures for a moderately long term.

Why are agar slants better for stock cultures?

Why are agar slants better suited than agar plates to maintain stock cultures? Slants are better suited because they can be capped, preventing the agar and culture from drying out. The cap also prevents airborne contaminates from entering the slant. Slants take up less storage space.
