Slants can have wood added to extend the storage life of the slant.

Injectable slants will be able to receive liquid culture from a syringe in a sterile way to test of syringe is clean and store your culture.
Vented and injectable slants will be able to receive culture from a syringe, and remain closed and have good growth because of air exchange even with tube closed.
If not using a vented tube, you will need to allow tube to be slightly open for gas exchange or culture will stop growing.
