Why is it important to incubate a plate upside down, the bacteria plate we're talking about here? so incubating agar plate upside down with the lid on the bottom and agar on the top is a common practice in micro bacteria.
00:16
So the main purpose is first of all, prevent, prevention of condensation.
00:34
So when agar plate are incubate the right side up, a lot of condensation coming out from that form inside the lid can fall onto the agar surface so that you will have a lot of excessive moist or water that interfere with the growth of micro bacteria.
00:52
They're not able to grow or spread the colony and they can cause contamination.
00:59
So this is why you have to go upside down.
01:02
So the condensation collect in the lid instead of on the top of the agar surface.
01:08
So this is the main reason that we have to do the upside down.
01:12
As i just mentioned, this is the right side up.
01:17
So the agar is made of a lot of liquid.
01:21
So the condensation is gonna go down and then it's gonna accumulate it.
01:28
So you'll have a layer of liquid on the surface of the agar plate.
01:33
Again, this liquid is going to interfere the colony growth...
