[Preplabstudents] Autumn- Week 4

[Weaver, Tyler A.]

Howdy y’all!

Week 4 is up next! This is our first week with Monday labs doing something different from the rest of the week. Be sure to pay attention to the lab schedule, it can get weird.

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

MML
Model kits will be provided on the bottom of the reagent carts or on the bench beside Hood A. We do have replacement parts in 130 CE if needed.

MSR
Be prepared to direct students to the window cart for replacement pipets, beakers, and pipet pumps. Restock the cart as frequently. Burets are in the back of the window. We have a bin for broken burets, in some cases we can salvage them. (List price is ~$200 per buret)Please keep any pipet pumps that have broken off pipets in them- we should be able to salvage them.

FPD
Be prepared to direct students to the ice machine outside of the restrooms. Check the ice machine every 30 minutes- set a timer to remind you. There is no scoop provided, students should just use a beaker from their drawer. Freezing point apparatus will be on the reagent carts or on the bench beside Hood A. Replacement parts will be in the windows. Note that the inner tubes in this apparatus is just the 50 mL tubes we keep on the window cart. Extra batteries and tiny screw drivers will also be available in the window.

SYN Day 1
Be prepared to direct students to the ice machine outside of the restrooms. There is no scoop provided, students should just use a beaker from their drawer. Extra red flea size stir bars and vacuum tubing will be available in the window. Sarah and I will manage the microwave. Note that concentrated phosphoric acid is not needed for Day 1 and will not be provided. Each room will have a microscope. We will snag a tiny amount of sample from the first group to obtain crude product to put under the microscope. If students observe the temperature on the digital readout going down as they heat up their melting point apparatus, they plugged the thermocouple in the wrong way. They just need to remove it, turn it 180˚ and reinsert it. Replacement thermocouples will also be available in the window. Each room is limited to only 6 groups due to the layout in the microwave. If a room asks for more reaction tubes, please check they don’t have more than 6 groups before handing anything out. Any questions you cannot answer should be directed to me.

EMS
These will be set up on the bench beside Hood A. Replacement parts are available in the window.

Other Important Information-

Freight Elevator

Starting Monday September 9th, the freight elevator in Celeste will be shut down until at least the end of November so that it can be modernized. This is the elevator that we use to transport chemicals and waste between the prep lab and the gen chem labs on the 2nd and 3rd floors. With the freight elevator unavailable, we'll be using the passenger elevator as needed. Alternately, the elevator in Evans can be used. You would need to take your cart across the glass walkway into Evans, catch the elevator, then take the glass walkway back into Celeste.

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.

Missing Shifts

If you have an absence you know about in advance, you are expected to find a sub to fill your spot. Regardless of whether you are able to find a sub, you should send an email to preplabstaff at lists.osu.edu<mailto:preplabstaff at lists.osu.edu> to let us know of the absence. If you were able to find a sub, please tell us who it is and cc them on the email.

As always, please let us know if you have any questions or concerns.

Best,
Tyler
