Have you Ever Pipetted By Mouth?

[butters]

so far no. was never given the chance and nobody taught me how. when i was starting my life in lab am only get the glimps of the tubes and the pipet. and was strongly warned not to pipet by mouth...

Using glass pipette? Yes.
Lots of time during my chemistry and biochemistry courses. I still don't get it why we were left alone in the lab from time to time... :-)

Never would try to pipette some of the chemicals by mouth though (having in mind ethidium bromide for example).

Yes, using glass pippette, when I was still high school learning chemistry. I wonder if that method was true, because we were taught to do so! And my classmate almost sucked H2SO4! Anyway, a suctioning balloon should have been already invented.... never again would I do that, though...

yes - common place in sixth form chemistry in the 80's. Best gag was to 'helpfully' hold the beaker containing the solution to be pipetted for your mate whilst they pipetted (thio sulphate was horrible and left you with a horrendous 'coated teeth' sensation), then as the pipetting was approaching completion, suddenly drop the beaker so as to expose the end of the pipette to the air - hey presto, air would rush in and cause a gob full of solution to shoot into colleagues mouth. Obviously you had to pick and choose which substances you did this with. Source of great amusement.

yes once when i was in +2 class

[admin]

LOL welcome to the forums Bhappy...what is a +2 class?

[kingnothing]

this is strange
I thought only in my college this happens since we lake alot of equipments
and solutions
I guess this is the only way I can say Im an expert in
