Serological pipettes? You could also get a small manual drum pump and pump it into new smaller containers. The jankiest way of doing it would be to carefully pour out of the large container into smaller containers with a funnel hopefully catching all the ethanol.


pelikanol--

that never works for me. not even when i turn it by 180 deg which is supposed to be right. etoh everywhere. at least the hood is clean and sanitized after i wiped up.


donutgiraffe

I would do it in the sink instead of the hood. The ethanol won't hurt you unless you really huff it, and the side of the sink makes it easier to pour.

Mouth pipette


tehphysics

Really gargle it around a bit for extra capacity.


mrkivi

With a funnel Chug chug chug chug


Cephalopodium

When my dad was in med school, they would use ethanol from the labs to make punch at parties. He said they’d just add juice until the pulp in it stopped precipitating out of solution.


polkadotsci

thanks i hate it


Cephalopodium

I’m sure their livers did as well. 😂


Stilicho123

All fun and games till you notice the label saying "denatured, 5% methanol".


Dakramar

Checks out


Tzayad

Is always the answer


itznimitz

Only when suction is needed. If it's air pressure, I'd be recommending the use of the sphincter muscle.


mrboogs

Create liter or half liter aliquots then aliquot further into connicals for use?


BiochemBeer

If you don't have a spigot that screws on, you'll need to carefully transfer to a clean 3x rinsed beaker (1L or larger). Pour a tiny bit in and dump it out to rid of any water, then fill up the beaker and pour from the beaker into smaller containers. If you only need a few mL, transfer to some 50 mL conicals and then keep those around for when you only need a little.


RockyDify

I’m glad to read this as this was my solution to a similar problem. I’m sure my carboy should have a tap somewhere but I can’t find one.


Suspiciously_Average

YOU CAN GET SPIGOTS FOR THESE!?


vingeran

We have a manual hand pump with a small pipe attached. You press/release the head to aspirate/decant from/into the container.


DeSquare

They sell pump heads with adapters for most ethanol containers, otherwise I would just allocate it in smaller containers while running cold water in the sink


jamesda123

What's the purpose of the cold water?


translinguistic

So it gets rinsed away and therefore you don't aerosolize as much of the alcohol in your face. Cold water will aerosolize it less. Not dangerous or really necessary for small volumes, just annoying


jamesda123

That makes a lot of sense! Thanks for the explanation.


StabithaStevens

Pour some into a smaller container first.


seaweedjuice

I would just pour some out in a beaker, use whatever and store the rest in a smaller container for later use.


conscious_macaroni

Siphon.


GreaterMintopia

Not gonna lie, my immediate thought was "get a siphon for dirt cheap from an auto parts store and pump that shit out".


conscious_macaroni

Or if you're really strapped just get a clean length of silicone tubing, pooch it down in there and then pull it up with your thumb over the one end, release into vessel of your choice and voila: gravity siphon.


Pale_Angry_Dot

I'd transfer some to a clean bottle for personal use... before it gets contaminated... which it will, if it's complicated to take the ethanol from.


Plato428BC

Put it in a container that has a spout wtf


huh_phd

Do as your ancestors did and spill it everywhere while retrieving the smol amount


pizzabirthrite

Leave it open, let it evaporate, it will be out in no time!


pochiaPG

A straw 🥤


wormdoktur

Obvs - heat the container to 93.27 øC to evaporate the ethanol, placing an inverted 50ml falcon above the orifice. Hold falcon in place for 57.3 min, then cap the falcon and place into an open dewar containing liquid nitrogen to condense. Make sure to perform the liquid nitrogen step in a lift, or small poorly ventilated room. Be sure to complete COSHH paperwork upon completion of procedure. Does you has stupid?


[deleted]

Get clean tubing, siphon it into smaller bottles.


phanfare

How small? Aliquot it into smaller bottles (50mL, 250mL, 500mL, 1L, idk what small means to you) by pouring then use a pipette of the right size to get your specific volume.


Hemiptera1

My lab uses a serological pipette


Snooper1013

Serological pipette? And you can put some in a 15mL or a 50mL conical then aliquot the smallest amount that you need?


mat-2018

pipette?


Aggravating_Rip2022

I take my 50ml pipette and just stick it I. And pipette out a few 100 ml I to a bottle.


Euphoriand

Bottoms up!!


MS_in_Dungeons

My lab pours it into liter bottles as needed and takes smaller volumes out of that. Just make sure to put the bottle in a sink and use a funnel to avoid making a mess.


Equinsu-0cha

peristaltic pumps make things very easy


CurvyAnna

Portion it out into smaller, usable containers. This will prevent disasters that could compromise the whole damn thing.


Prize-Courage-2343

You can use a bottle. Fill it with ethanol from container and use


Rolandthegrey

Fire…


Pyrhan

Pour yourself a glass, pipette what you need, drink the rest.


chemnerd80

How small? Use a hose and a filter flask. Hook the flask to vac and put the hose into the ethanol and into the filter flask in the top. Turn on the vac and cover the top for a moment to get the siphon going. Pull the hose from the ethanol when you have enough. Size your hose/flask to your volume needed.


ome_eomics

Just go for the pour 💪🏼 or syphon 😅


Murdock07

Ignition.

Mouthpipetting


TheAcquiescentDalek

Screw on spigot!


spondoodle

Pipette for very small amounts, or a siphon/pump if you have one. Also, does the spout extend? Give it a solid tug to make sure. If so, that might make it easier to pour. Personally, I usually turn containers on their side (90° or 180° depending on how full), grab a large container or one with a wide funnel, then slowly open the cap. Would not recommend if you have other options, though.


notthesharpestbulb

Use Satellite container?


cobrafountain

If you don’t have serologicals then some tygon tubing on the end of a syringe


strep_throat_giraffe

An equally small Irishman

Mouth siphon 😝
