Because it stops them breedingWhy are you sterilising film cannisters?
Are the tops LDPE and not PP? LDPE melts at 110'cNot melted like pieces of white ear wax! The tubs show what should have happened (ie nothing, they survived 15psi / ≈121ºC).
That just raises further questions!Lack of sterile environment (no flow hood mainly) so I don’t have to pour my agar cultures.
Yep still none the wiserThat just raises further questions!
