[Weaver, Tyler]

The Weekly Mix
Volume: Autumn 2025 | Edition: Week 6
Schedule

Last week had a lot of surprises for us (no water, poo, a shower pull), hopefully Week 6 is a bit calmer. Here’s what we have scheduled:

Experimental Details

Review the window notes and any associated equipment guides for additional details.

Please see the Week 5 edition<https://lists.osu.edu/mailman/private/preplabstudents/2025-September/000299.html> for details on PbI and BAR.
MML

Model kits will be provided on the bench beside Hood A. Sarah and Emma have replacement parts in both windows if needed.

CYC

TAs will pick up samples of CuO at the start of lab. These will be kept in the labeled bin on the unknown shelf. Unknown bins should not be removed from the unknown shelf. Only hand out full sets of unknowns to TAs. Any leftovers should be properly disposed of by the TA at the end of the lab session.

CLK

Extra thermometers and replacement batteries will be in the window. This one usually uses a bunch of spill kits. Keep a close eye on your spill kits and request replacements as needed.

LLT

Blue square carboys of 0.44 M NaOH will be swapped out during the lab readiness checks by those completing them. When swapping out the blue carboys, check the fill level of the spill tray. Let us know if it’s more than half full. Partially filled bottles of lemon and lime juice should be placed in the fridge. We will periodically combine these. When doing a gather, please check the fridge first for full bottles of lemon and lime juice. If you need more than what is available in the fridge, please grab new bottles from aisle 28. No partial bottles of lemon or lime juice should be left in aisle 28.

XUF Day 2

We will be moving a large instrument into Hood A of 330. A tank of acetylene will also be clamped to the bench near this hood. While the instrument is in this hood, the orange bucket will temporarily be placed under Hood A.

General Information

Consumables

Please follow the consumables checklist when restocking these items. We’re noticing deviation from this list again.

Cleanup of Abandoned Equipment

This is not the job of the Head TA or the ALS. We have a task scheduled at least once per day to clear out any equipment that has been abandoned in common areas. If you have questions about this, please see Tyler.
