From weaver.646 at osu.edu Sun Feb 1 18:41:26 2026 From: weaver.646 at osu.edu (Weaver, Tyler) Date: Sun, 1 Feb 2026 23:41:26 +0000 Subject: [Prep Lab Students] Spring 2026- Week 4 Message-ID: The Weekly Mix Volume: Spring 2026 | Edition: Week 4 Schedule It?s week 4, which means it?s time to try something truly radical: a full week of lab. Monday sections will, at long last, be having lab. [image.png] Experimental Details Review the window notes and any associated equipment guides for additional details. Please refer to last week?s edition for details on SOL. DAG Materials will be provided on the bench beside Hood A. Be prepared to provide replacement plastic 50 mL graduated cylinders. The students tend to put these in their drawers instead of returning them. There are now enough brass pieces of each type for each student to have one. EMS These will be set up on the bench beside Hood A. Replacement parts are available in the window. The power supplies and discharge tubes are new, but the spectrometers are the same. FPD Be prepared to direct students to the ice machine outside of the restrooms. Keep an eye on the ice machines, let us know if it?s getting low. If the machine is getting low, we can top it off with ice from the prep lab. We do not provide an ice scoop to students; they should just use an empty beaker from their drawer. The FPD apparatus guide has details on replacement parts and repairs that can be done within the lab support window. Everyone is required to read the current version of the FPD guide. We?ll have copies of the FPD guide in the windows and in the prep lab office. Everyone must read it. After reading, you must initial on the roster next to Keyth indicating you have read through it and understood it. Let us know if there are any gray areas. QUL All rooms have a significant stash of 1.7 mL microcentrifuge tubes behind their marker boards. The students will be using the centrifuges for this- if they report one is not working, check the following: it?s plugged in, turned on, and the lid is fully closed. If it still doesn?t work, trade it with one of the extras in the window. Place a broken item sticker on the faulty unit. When doing cart checks for this experiment, swap the entire bin of reagents regardless of fill level. Do not check individual bottles- it takes too long. SAL Additional colorless empty microcentrifuge tubes are stored behind the marker boards. Only emptied and rinsed centrifuge tubes should be placed in the blue bucket. Blue buckets should be swapped out during waste runs if they are more than half full. If you see any leftover tubes of solids on the reagent carts when doing your checks, please give them to the window- window people, please put them in the ?partial unknown sets? bin. Other Information Evening Dismissal Around closing time, Emma and Sarah will dismiss students early if everything that needs to be done is completed prior to the end of the scheduled shifts. This should be reflected properly in your timesheets. Window Stuff If someone gives you something that is broken, by default, please offer a replacement of that item. We?re still struggling a bit with the red lids on the blue buckets. When blue buckets are not in use the red lid should be placed on top of the bucket. When they are going to be used, the red lid should be placed under the blue bucket or at least flipped over so you cannot see the ?this bucket is not in use? sticker. Leaving this sticker in view of an ?in-use? bucket can be confusing. Vacuuming When using the backpack vacuum in the labs, please be sure to move the reagent carts and sweep the area where they were sitting. Dust and hair tend to accumulate there. Please also open the doors to the AV cabinet and sweep the floor in front of it and any obvious dust that is not in a sensitive place. Absorbent Pads We have several types of absorbent pads available in the lab, so it?s understandable if you find it challenging to decide what should be used. A summary is listed below, but if you?re ever unsure please just ask. Yellow pads- are for chemical spills Gray pads- are for spills that can be disposed of in the trash. Think mud, coffee, melted snow, etc. Large blue pads- these have blue backs and are for the sliver carts. Medium blue pads- these are for the blue carts. These pads are currently blue with white backs but will change to white with white backs. Small blue pads- these are blue with white backs and are for the shelving in the prep lab. Cart Changes Reference the gather sheets when completing cart changes and chemical removals. We?ve seen mistakes that could easily be avoided with both tasks had the gather sheets been referenced. Additionally, be sure you are switching any dirty liners on carts when doing cart changes. Friday Waste Runs Dr. Moore, our chemical safety coordinator has specifically instructed us to not leave any waste upstairs over the weekend. To comply with this, please glance at the waste beakers when doing Friday night waste runs on all rooms, we?ve seen waste left behind. On the same topic, please be sure to replace any used 6 M NaOH. I don?t have a waste run scheduled for Monday mornings because everything should have been taken care of Friday night. If the 6 M NaOH is not replenished on Friday night, the Monday morning sections will be at a disadvantage. General Chemistry Prep Lab ? Department of Chemistry and Biochemistry ?

[image.png] Experimental Details Review the window notes and any associated equipment guides for additional details. Please refer to last week?s email for details on DAG and FPD. PPG All rooms have a significant stash of 1.7 mL microcentrifuge tubes behind their marker boards. The students will be using the centrifuges for this- if they report one is not working, check the following: it?s plugged in, turned on, and the lid is fully closed. If it still doesn?t work, trade it with one of the extras in the window. Place a broken item sticker on the faulty unit and place it on the broken items shelf. When doing cart checks for this experiment, swap the entire bin of reagents regardless of fill level. Do not check individual bottles- it takes too long. MSR 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 or are leaking in the designated bin- we may be able to salvage them. Details on where to place these broken items are available in the window notes. As a reminder: TAs, Lab Supervisors, Prep Lab Students, nor Prep Lab Staff are permitted to clean up blood. This needs to be done by FOD or EHS- this will be coordinated through one of the Prep Lab Staff. PbI Solids will be passed out from the lab support window. Do not give out partial sets at the start of lab. We?ll be using the vacuum ports for this experiment; the TAs do not need to do anything with the vacuum pump. Be sure the vacuum control knob in the second-floor window (by the fire extinguisher) is in the ?auto? position We will also be using the ovens; they open by pulling the bottom of the handle up towards the ceiling- no rotating required. We strongly encourage TAs and students to keep the oven doors closed as much as possible. This helps with heat loss. BAR The spectrometers use the same power cord as the hot plates. There is a ?broken UV-Vis? cart in the window. Please place any broken UV-Vis on this cart immediately as they are reported. As always with anything broken, please put a broken item sticker on it describing the issue. When doing the cart check for this experiment, please swap all allura red bottles. We can check and refill them down in the lab. 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. SST If a lab indicates they don?t have enough meters and probes, be sure they are planning to work in pairs. pH meters, probes, and cables to connect the two, are on the bench closest to Hood A. There could be a few rooms with old (black cable) probes, most rooms will have new (white wire) probes. The probes with the black cables will need to be attached to the top of the meters whereas the new white wire probes will need to be attached to the probe and meter via the white wire. Connections are made on the top of the meter by pushing and turning (BNC type). Both pH probe types will have either a black o-ring or blue rubber piece at the top of the probe shaft to cushion it from the glass storage tube and help seal in the storage solution. These should stay at the top of the probes while the students are taking readings. If a student claims their pH meter is ?broken?, they should have their TA try to calibrate it before bringing it to the window for an exchange. Emma has prepared a guide on how to handle pH meter issues, everyone is required to review it. It will be available in the window and the prep lab office. Other Information Clean Your Dirty BuckIDs We?ve left some alcohol wipes on the top of Keyth. If the magnetic stripe on your BuckID has junk on it, please use the wipe to clean it off. Locking & Unlocking When assigned to lock or unlock labs, you should be on the assigned floor by the start time of that task. Our promise is to have the labs open 15 minutes before the session starts. Window Tasks Tyler looks through all of the completed forms. There have been some window tasks recently that have not been initialed. Please be sure you are completing these tasks and initialing the mini daily sheet when they are done. Calling 911 When someone feels dizzy, lightheaded, or like they are going to pass out, calling 911 to have EMS look at the person is not optional. I got an incident report this week that indicated a student was feeling like the could faint. The incident report indicated that 911 was not called. General Chemistry Prep Lab ?

MML Model kits will be provided on the bench beside Hood A. Replacement parts are available in both windows if needed. CPC The distillation apparatus needs to be unplugged when not in use. Ideally, the water pump and heating mantle should be plugged in and turned on about 10-15 minutes before the lab session starts. The apparatus needs to be checked at least every 30 minutes by someone from the lab support window. Set a timer for 30 minutes to remind yourselves. This video shows how to add ice and transfer water from the receiving flask to the heating flask (still pot) properly. You must watch this video prior to the start of CPC. Remember the end of both pieces of tubing (from the condenser and to the condenser) should be inside the bucket. If you need to stop heating the flask for any reason, turn the heating mantle off and lower it away from the flask. This is why we set them up so high- it makes it easier to kill the heat quickly. 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.

[image.png] Experimental Details Review the window notes and any associated equipment guides for additional details. Please refer to the Week 6 Edition for details on MML and CLK. STR This is one of my favorites! Students should try to keep their samples under the snorkels as much as possible. This will help immensely with the odor in the room. PbI Solids will be passed out from the lab support window. Do not give out partial sets at the start of lab.

We strongly encourage TAs and students to keep the oven doors closed as much as possible. This helps with heat loss. 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. Unopened bottles of lemon and lime juice from carts checks should be placed back on the shelf in aisle 28. LCP Students will be using ice toward the end of lab. We do not provide scoops for ice, instead students should use an empty beaker from their drawer. At least one glove should be removed when walking through the hallway. If students are in the hallway with two gloved hands, please gently ask them to remove one glove. Additional commentary is not necessary. VOL This one has A LOT of equipment and solutions. Students will be using the multimeter kits which are on the bench beside Hood A. If they report that one is not working properly, please just swap the broken part for one of the replacements in the window. Emma has made a guide on what to do with these. Please read it. The provided electrode kit is to be used for both Parts A and B. One magnetic stir bar is provided in the kit to help distinguish between iron and zinc electrodes. The students will be sanding the oxidation layer off the electrodes with emery paper/cloth. This should be done on the provided cover stock; the cover stock should be placed on the provided black plastic tray. The whole sanding procedure should be done under a snorkel. Each room has been provided with 7 trays since they only have 7 snorkels. We will not provide more. Students should not be sanding directly on the lab bench. Doing this makes me sad :( There?s a ton of waste for this experiment. Liquids should be discarded in the chemical waste beakers (white can). All rooms have a third white can under the hood. If you do a waste run and take three cans from one room, replace the third can that was taken from under the hood. Contaminated paper, including spent emery paper, should go in the blue bucket. Spent electrodes should be collected in the canister in the window. Spent porous cups and Pasteur pipets should be discarded in the orange bucket. Other Information Ethanol Spray in the Prep Lab If you empty a bottle of ethanol spray in the prep la (usually from cleaning tubs) please replace it with a new bottle from the cabinet. Lab Coats If you haven?t replaced your lab coat in the last few weeks, please do so. General Chemistry Prep Lab ? Department of Chemistry and Biochemistry ?

This module reaffirms Ohio State?s Shared Values and helps us understand our responsibility to maintain a university community free from discrimination and harassment. This training is designed to ensure that the Ohio State community is fully aware of our policy regarding harassment and discrimination, as well as the duty to report any incidents related to protected class harassment and discrimination to our Civil Rights Compliance Office (CRCO). The module also includes guidance on identifying and responding effectively when issues arise, as well as strategies to help empower our community to step in when they witness unacceptable behavior. If you encounter or witness any form of protected class harassment or discrimination, you can report it to CRCO, and if you have any questions regarding the training, please contact crcoeducation at osu.edu. Thank you for your commitment to ensuring a safe and supportive university community.

Casual conversation is fine while completing assigned tasks, but it must not distract from your responsibilities. Speaking negatively about coworkers?staff or fellow students?is not acceptable under any circumstances and undermines the professionalism we expect. Time spent socializing, particularly at the window, in the hallways, or in the teaching labs, must be kept to a minimum. Extended conversations in these areas interfere with productivity and customer service expectations. Your priority during each shift is to complete assigned duties efficiently and support the overall operation of the lab. If you need to step out briefly?for example, to pick up food or take a phone call?that is permitted. However, it must be brief, and you are required to notify us when you leave the building during your shift and when you return. This is a safety requirement, so we always know who is present in the lab spaces. If you have concerns about the fairness of assigned tasks or how work is being distributed, bring them directly to me. I am happy to discuss them, but concerns must be addressed through the appropriate channel rather than through conversations with others.
