Experiment Notes-Refer to the window notes and gather sheets for additional details.

STO
TA demo kits will be on the reagent cart or on the bench beside Hood A. These include a jar of sand for smothering a Mg fire if it gets out of control. The sand does not need to be used if everything goes to plan, the Mg strip should burn itself out. The Mg strips should be on the reagent cart, not in the demo kit. The students will no longer be using the centrifuges for this experiment.

LLT
Be prepared to hand out lots of burets, pipets, pipet pumps, and blue stoppers. Please refill the window cart when things start to get low- this goes for all items on the window cart, not just the items used for LLT. Blue stoppers are in one of the drawers within the lab support window. The 0.44 M NaOH carboy should be kept on the carboy spill tray beside hood A. If the drip tray gets full, let us know so that we can empty it.

We will be swapping the carboys out after each session. We will not do this as part of the cart check, but as part of the lab readiness check- room numbers will be highlighted in yellow on the daily sheet. We’ll have a spot for partially full carboys to be dropped off in the prep lab. The prep lab staff will take care of combining carboys so that we’re ready for the next round of swaps.

If the lemon or lime juice bottles are not less than ½ full, please do not swap them. Partial bottles should be put on the designated shelf so that we can combine them and send them back up.

LCP
Students will be using ice toward the end of lab. If you are in the window, please keep an eye on the ice machine, and break up any clumps that are present. Students will not be provided with salt for their ice baths. Keep a close eye on the 25-mL test tubes, if they need refilled, more are available behind the marker boards.

IHT
Materials will be available on the reagent cart or on the bench beside hood A. Cups and lids will be in a red dispenser by the balances. When completing lab readiness checks, please keep an eye on the cups and lids and refill as necessary.

MGB
Model kits will be provided on the bottom of the reagent cart or on the bench beside hood A. We have replacement parts in the prep lab if needed.

Other Important Information

Covers and Shift Switches
Please remember that a cover or shift switch is not official until an email is sent to preplabstaff at lists.osu.edu.

Training Items
If you have outstanding training items, please get them completed. This includes the title IX training.

Elevator

Reminder: With the freight elevator unavailable, we are using the passenger elevator as needed. Dr. Moore has requested that if chemicals or waste are being moved in the Celeste passenger elevator, only the personnel moving these items travel in the elevator, no other passengers. With that in mind, the general population can still use the passenger elevator, but priority will be given to those that need it for accessibility reasons and for the transportation of chemicals and waste. If a priority individual needs to use it, we'll pause chemical and waste transportation and allow them to complete their journey first. We strongly encourage students to use the stairs when possible. Students also have the option to use the elevators in McPherson, Newman-Wolfrom, or Evans. Although those elevators will not get them to the 4th floor in Celeste, they will at least cut down the number of stairs they will need to take by getting them to the third floor.

Full Bottles when Gathering

Please be sure you are grabbing full reagent bottles when completing a chemical gather. If you are unable to find full bottles, please let one of the prep lab staff know. We can determine if bottles need to be refilled, combined, or additional solution needs to be made.

Fall Break

We will follow our normal schedule Monday, Tuesday, and Wednesday the week of fall break (October 7th, 8th, and 9th). However, the prep lab will close at 6:30 pm on Tuesday and Wednesday (October 8th and 9th). The prep lab will be closed all day on Thursday and Friday (October 10th & 11th).

Best,
Tyler
