How often do I need to change the AAs filter?

Whenever you notice that the delivery of AA to rv or to mv is slow.

How long does the nitrogen tank last?

It depends on the number of the syntheses and the length of each synthesis. For 15-residue peptide, it should last at least 20 to 30 peptides.

Are the AAs vessels under pressure during the synthesis?

No, only while the AAs are emptying or transferring.
