Lab safety! Your hair will catch on fire

Sorry to ask the irrelevant question, but what background music is played? Which ethnics is it associated with?

Thanks very much for the demonstration.

I would have used a Gilson, that pipette was dripping.

Pls answer me guys I really need help. I am asked to perform total plate count/aerobic plate count on a pasteurized fruit juice. I need to prove that the product is safe to drink. My teacher told me to make 0, -1, and -2 dilution. If I want to prove that my product is safe thru microbiological reasons does that mean that all my plates should have 0 count? Is it fine to have count at the range of 30-300? Or does 30-300 count mean that my juice product is not safe to consume? TY!

thanks for the demostration.

TBH, I really like micropipetters rather than disposable serological pipettes. It helps keep everything moving quicker, which helps cut down on potential contamination, and the tips can just be popped into a biomat bag.

[virtualetude]

how come she didn't flame the cap?

[luftair]

pipettes gotta be on the vertical...and you have to open the plate near the bunsen...

[lady2no6sorrow]

YEAH, she need to cover her hair... but anyway this remember me my labs... jjejeje like it!

[alllitangio]

Doesn't she have to wear mask and gloves???

[katie89100]

@alllitangio It's just milk, more protection may be needed once the bacteria have grown.

[theninja89]

its conor o bryne!!

[rupaliize]

yes the agar plates should be brought near to th flame which she has nt done once .....

[cactusbrandy]

i dont really get what she did at the end.

but anyway this helped me prepare for my lab!

[sid025]

Helped me a lot understanding Serial Dilution

[sariyathul]

whenevr u want to open the petri dish (containing the agar/agar plate ) it has to be brought closer to the flame with the mean to ensure sterility...its not only when u open the tube .tie her long hair please..better cover it ;-))

i add this to my fav anyway..
