[–] [email protected] 20 points 10 months ago

Sad pipet noises

[–] [email protected] 46 points 10 months ago (4 children)

Explanation? Are these guys huffing ether or something?

[–] [email protected] 87 points 10 months ago (1 children)

They pipette by mouth, which is not very safe.

[–] [email protected] 82 points 10 months ago (1 children)

but how are we supposed to accidentally discover artificial sweeteners?

[–] [email protected] 35 points 10 months ago (1 children)

By distilling piss from diabetic people? Idk I'm not a scientist i just like the memes

[–] [email protected] 13 points 10 months ago (1 children)

WTF? Piss is all natural!

[–] [email protected] 9 points 10 months ago

unless you drink from the pipet

[–] [email protected] 41 points 10 months ago (1 children)

They are using their mouths to suck liquids into pipettes. It was an old and dangerous lab technique.

[–] [email protected] 9 points 10 months ago (4 children)

Then how are we supposed to do that?

[–] [email protected] 29 points 10 months ago (1 children)

Use a rubber bulb on the end of the pipette. That way your ~~cartel members~~ lab techs are safe.

[–] [email protected] 7 points 10 months ago (3 children)

We still use mouth in secondary school. I guess its same in undergraduate degree too. But yeah we only take the base in acid-base titration in pipette

[–] [email protected] 8 points 10 months ago

Jesus Christ. 20 years ago my chem teacher used to tell me about the bad old days of having to do this, that it's still happening today is horrifying.

[–] [email protected] 7 points 10 months ago (1 children)

definitely not standard procedure here in the US. And basic solutions can be more dangerous than acids.

[–] [email protected] 3 points 10 months ago

I guess they only gjve non toxic bases for school

[–] [email protected] 2 points 10 months ago (1 children)

Now you know

[–] [email protected] 2 points 10 months ago

Poi ump

[–] [email protected] 21 points 10 months ago (3 children)

I am a bit concerned everyone is just mentioning the squeeze rubber ball thing, maybe because its time appropriate for the images.

But in modern times people should use something like this https://www.integra-biosciences.com/global/en/pipette-controllers/pipetboy-acu-2

[–] [email protected] 5 points 10 months ago

That's the worst squirtgun ever.

[–] [email protected] 3 points 10 months ago

I love my drummond, if only it came in cool transparent colors too 🥲

[–] [email protected] 2 points 10 months ago

We use drinking straws. You just do the "tap the top opening of the straw really fast" trick and it sucks the medicine right up.

[–] [email protected] 6 points 10 months ago

rubber bulb. its a bit like the end of an eye dropper if you ever used the old fashioned kind. The modern ones are actually sorta complex where you can let go and the liquid will stay inside and you press an area near the kneck which will release the vacum. back in those days it was just a bulb and a bit frustrating to use so they did this dangerous technique.

[–] [email protected] 3 points 10 months ago

With a squeezy rubber bulb thingy.

[–] [email protected] 40 points 10 months ago

Basically it took many years before someone developed something that could be run with a trigger or button. Before that you used a vacuum (your mouth) to pull liquid into a pipette. Heard an older chemistry professor talk about a colleague who years before swallowed a salmonella sample by accident. A lot of people surely got hurt this way.

[–] [email protected] 12 points 10 months ago (1 children)

not a scientist but I'm guessing they are siphoning some chemical by sucking up a small amount in the tube to transfer it to another container

[–] [email protected] 9 points 10 months ago

Aww, I thought they were blowing bubbles. Looked like fun.

[–] [email protected] 33 points 10 months ago (1 children)

Look how long their fancy straws are! I bet they keep chemicals a safe distance away from possible ingestion!

[–] [email protected] 3 points 10 months ago

I'm wondering if a crazy straw was tested...for safety

[–] [email protected] 19 points 10 months ago

lol lol let me suck up this salmonella sample real fast

[–] [email protected] 8 points 10 months ago (1 children)

I thought they were sipping pee to test for diabetes 😋😌

[–] [email protected] 8 points 10 months ago

Uh, yeah, suck it, pipet boy.

[–] [email protected] 4 points 10 months ago

The silliest of straws.

[–] [email protected] 4 points 10 months ago

Pipettecore ftw!?
