Sterile Pre-Poured Agar Slant for Long Term Culture Storage

Pre-poured agar slants are sterile test tubes with MEA (malt extract agar) that are used to store cultures for the long term. This mix of agar has significantly less malt extract to inhibit over colonization. The agar is also allowed to harden at an angle hence the name "slant". 

Long term culture storage is crucial to maintaining a viable or high performing cultures. Typically slants are kept in cold storage like a refrigerator to slow the expansion of mycelium. Slants provide a viable long term storage media that can last quite literally years.
