[Preplabstudents] Week 9

[Weaver, Tyler]

Howdy Y’all!

We hope you were able to get some rest and relax a bit over fall break. Week 9 is just around the corner. We’ve only got four more weeks of lab left!

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

CAR- TAs will be picking up glucose test strips from the windows. These are light and moisture sensitive.

EMS- Extra lamps will be available in the window.

SST- pH meters…Students and pH meters don’t always get along. pH meters with probes are on the reagent carts. 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. Sophie and Alec will have replacements in the windows. “Broken” meters should be placed in the labeled bin so that one of the prep lab staff can check them and make any necessary repairs. Extra wetting caps are available in each window, these are the little bottles that the probe tips are stored in. We also have extra storage solution, the liquid that goes into the wetting cap, in each window if needed.

XUF Day 1- Pennies are in the window. Alec and Sophie moved a large instrument into Hood A of 330 for XUF Day 2. It includes a tank of acetylene. While the instrument is in this hood, the orange bucket will temporarily be placed under the hood.

SYN Day 1- Ice will be needed. Please fill a cooler from the ice machine on the second floor.

Other Important Information-

Students Checking Items Out From the Window

As a reminder, students do not need to check anything out from the windows. Everything they need should be on the reagent cart. They may need to look on the top and bottom. It’s easy to miss equipment when there is a lot going on- so please help the TAs when necessary.

Unknowns

[A white card with red text and symbols  Description automatically generated]
We have made some adjustments to the placement of unknowns in the windows. They are now on dedicated shelves and the labeling on the bins has been upgraded to be clearer and include basic safety information. Please keep the bins on the designated shelves so that everyone can locate them easily. Let us know when a bin is starting to get low so that we have adequate time to get another from Evans.

Security

Please be sure if you are the last person to leave a space, you close and lock the door behind you. We had an issue on Tuesday with doors in Evans left open with nobody around. Additionally, we will no longer be propping the door from 150 CE into the hallway open, nor will we be unlocking the door to 140 CE. Someone will need to enter 160 CE and open one of the other doors to move in carts.

Segregation of Incompatible Substances- Carboys

If you’ve looked closely in Evans, and the prep lab before we moved, you will have noticed that all our chemicals are stored in groups with similar properties: acids, bases, oxidizers, inorganic acids, organic acids, poisons, flammables, etc. A similar logic is used for storing our stock carboys. We have added colored tape to the lids of the carboys to help distinguish our five groups of carboys: bases, acids, oxidizers, flammables, and “benign”. Until we move back into 130 Celeste, the oxidizers and benign carboys can be stored together. If see you something out of place, please say something.

GroupMe Replies

The GroupMe is a great place to request reagents, spill kits, etc. The person running the supplies up, etc. should reply to the original message so that we all know it has been resolved.

Report=Support Title IX Training

Please remember that you need to complete the Title IX training by October 15th. Time spent completing this training should be included in your timesheet.

As always, please let us know if you have any questions!

Best,
Tyler
