Optimus, I am afraid that you do not understand.
Cross, I take it that you are experiencing contamination the majority of the time after the two week stage, am I correct? The clear square containers from phytotech are very good along with their other autoclavable flask and lid combo packs. What is happening though is even though you screw or push the lid down onto the flask there is still airflow going through that tiny gap between the lid and flask and that’s where the bacteria are getting in. So after plating flask you need to seal the lid with some clear tape stuff phytotech has or electric tape and that will give you an airtight seal. It’s always better to be airtight since airflow will dry out the media too
