We mainly use slip caps for the above media. They work fine for a couple
of monthes (up to ~6 monthes stored at 4°C; the only problem with long
term storage has been with water loss, not contamination). It is the only
way to go when large amounts of tubed media are being made (easier to cap
and de-cap). Hope this helps. Bye.
