Chemicals in pool

Common pool

As announced, I've cleaned out the cabinet used for chemicals at ISOLDE and I've kept following items for the common pool

Isopropanol: 2x 7.5l, 1x5l safety canister, 1 spray bottle
Aceton: 2x 7.5l
Methanol 1x 5l safety canister (not sure about exact quantity)
Ethanol: 2x7.5l of ethanol *more on this below

On top of the pool quantity above, I've kept the ISS dilution and a SPEDE canister.

A pallet has been set aside with everything I intend to dispose of. If any of the items belong to you and I was a bit too enthusiastic in deciding to remove them, please let me know as soon as possible.

Ethanol

As far as I understand, several collaboration use ethanol in their chillers and this was actually the chemical of which there were most containers. Nevertheless, I would also like to go to a pool system here, but it depends on your needs:

How much liter do you need for application? How often do you need it (continuous, a few times per year, once every few years, ... )
We should also explore if a dilution could be appropriate (example ISS: https://edms.cern.ch/ui/file/3090096/1/Procedure_Chilling_the_ISS_silicon_array_with_an_ethanol_dilution_v1.pdf) but this depends on the exact needs (freezing point). This could be another way to reduce the amount of chemicals, alternative to having the pool system.

General notes about chemicals

Size of packaging: please be mindful of how much chemicals you buy. Often, they are quite cheap and readily available, so do not stock up on unreasonably large quantities. Additional practical point: these large containers are much more difficult to store!
CERES: could you please check that all your chemicals are added to the CERES inventory, I've updated the pool ones. From my limited experience with CERES, it's convenient to use and I like the feature where you can indicate the specific location where the chemical is (instead of just 170/R-001 which is huge):
