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

Please see last week’s email for info on DAG and SOL.

SHM
Metals will be in a plastic box with a yellow label- they could be on the bench near Hood A. Cups and lids will be in the red dispenser by the balances. Additional cups and lids are available in the cabinet under the benches closest to Hood A.

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

MSR
Be prepared to direct students to the window cart for replacement pipets, beakers, and pipet pumps. Restock the cart 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 or are leaking- we may be able to salvage them.

FPD
Be prepared to direct students to the ice machine outside of the restrooms. Keep an eye on the ice machines, even out the ice regularly to keep the machine going, 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 a scoop to students; they should just use an empty beaker from their drawer. Freezing point apparatus will be on the bench beside Hood A. Replacement parts will be in the windows. Note that the inner tube in this apparatus is just the 50 mL tube we keep on the window cart. Extra batteries and tiny screw drivers will also be available in the window.

SAL
TAs will pick up sets of salts 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. Colorless empty microcentrifuge tubes will be available in the red bins by the balances. Additional colorless empty microcentrifuge tubes are stored behind the marker boards. Only empty 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 windows- window people, please put them in the “partial unknown sets” bin.

Other Important Information

Cart Moves
When doing cart moves, please be sure you are placing the carts in the correct positions. Carts going into storage are placed by the tallest window near hood B. The cart being used should be placed at the end of the oval bench closest to the shower. Bottles that are uncapped or fell over should be fixed before moving to the next room.

Glove Boxes
Do not stack boxes of gloves on top of the plastic box holders in the lab. This is a safety issue. The boxes can fall off and hit someone.

First Floor Demolition
Starting this week, the ceiling, lighting, and flooring on the first floor will be demolished after hours (10pm-7am). Following this, specific areas of the first floor will be closed while the new ceiling, lighting, and floor are installed. Further info about which areas will be closed off will be shared later.

Best,
Tyler
