Because the chamber shuts itself down, most farms run a second cycle overnight rather than stopping at one a day. Liquid media and tissue culture work are far quicker, around 30 minutes at pressure with rapid venting afterward.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary class=\"bmm-q\"\u003eCan I really leave it running overnight?\u003c\/summary\u003e\n\u003cdiv class=\"bmm-a\"\u003e\n\u003cp\u003eYes, and that is how most production farms get two cycles out of a day.
