Experimental Details

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

DPR
TAs should not need to pick up anything from the lab support window. Please see the notes below about glassware (pipets, pipet pumps, & burets), goggles, and lab manuals.

WRM

TAs should not need to pick up anything from the lab support window. We’ll keep a box of extra WRM pipets in the window on the bench. Please use this if a room runs out prior to the next cart check. When completing cart check gathers, please be sure you are only grabbing FULL beakers of plastic pipets. Please see the notes below about glassware (pipets, pipet pumps, & burets), goggles, and lab manuals.


Because of the long weekend, we have not yet put the sodium alginate on the 1208, 1210, and 1250 carts. We will put it out on Tuesday morning. The solution being a bit cold should not present any significant issues.

INK

TAs will be picking up INK unknowns from the lab support window. Remember that unknowns will be kept in the plastic boxes on the unknown/handouts shelf. Do not give out unknowns to students. We have put some extras of each pen, pencils, and blank chromatography paper in both windows just in case they are needed. Be prepared to give out 50-mL volumetric flasks. Please see the notes below about glassware (pipets, pipet pumps, & burets), goggles, and lab manuals.

Other Information

Goggles

If students need goggles that fit over their glasses, they can swap their “normal” goggles at the window for a pair of OTG goggles. This semester, we will be using the Fisher clear as our standard OTG goggle. If these OTG goggles still don’t work, we have a number of other options they can try. These are in a small white bucket in each window. These goggles should be cleaned with the provided alcohol wipes before students try them on.

Students in Chem 1110, 1208, 1210, and 1250 will receive a free pair of goggles from their Lab TA. If a student in a different Gen Chem course has never taken a chemistry course on OSU’s Columbus campus, they may stop by the window and get a pair of goggles for free. If they have taken chemistry on the Columbus campus before and do not have the goggles they were previously provided with, they’ll need to purchase a new pair from Chem Stores, 180 Celeste.

Everyone should be keeping an eye out for goggle box and lab coat packaging on the ground and benches. Please help keep our trash under control by picking up anything you see. Replace the bags in the blue recycling barrels as necessary. Extra trash bags are available in both windows. Emptied cardboard boxes should be broken down and placed in the hallway for recycling.

Lab Manuals

Boxes of lab manuals have been dropped off in each lab room. The boxes are stacked on the floor against the wall closest to Hood B. Each box has already been cut open for easy access. Emptied boxes should be broken down and placed in the hallway for recycling. Towards the end of the week, we may need to redistribute boxes between rooms to account for enrollment variances. If any of the lab manual covers were accidentally cut when the boxes were opened, set them aside, we can tape them and use them for TAs.

Pipets, Pipet Pumps, & Burets

Be prepared to direct students to the window cart for pipets, pipet pumps, and burets. Pipet pumps that “leak” and pipet pumps that have glass broken off in them should be collected in the designated bin.

What’s New in the Window

Emma has prepared an informational notice describing the changes that have been made to the window and its operations. You are required to read this during your first window shift.

Security- Locking Doors

When closing a floor, be sure that all labs are locked up. If there are two people assigned to the window, one person should lock the lab doors, the other person should later check that they are all truly locked.

If a lab is not being used, it needs to be locked. If you are completing a task that necessitates unlocking a room, please relock the room when you leave it.

We cannot leave the prep lab unlocked and unattended. If you are the last person in the office/lab and need to go somewhere please have someone come down to babysit the lab or grab key #1 in Keyth and lock up while you are gone. If Sarah and/or Emma dismiss the student employees before returning to the lab at the end of the day, the students should lock the door into the office and the door into the lab before heading out.

Timesheets

Please be sure you have submitted your timesheet for last week no later than noon on Monday.
