Hi Dr. Iverson, I hope you are doing well. I have counted the total pipettes in our lab, i.e 32. The breakdown is as below: 5ml pipette= 4 1000uL= 8 200uL= 7 100uL=2 20uL= 7 10uL= 1 2.5uL= 3

Similarly, we need to calibrate 4 of our weighing machines i.e 1. Located inside the anerobic chamber - 1 2. Located in nanohood- 1 3. Lab desk- 2

Please let me know if you need more information. Thank you so much.

Sincerely, Trisam ________________________________ From: Nicole Iverson iverson@unl.edu Sent: Friday, February 28, 2025 9:54 AM To: iversonlab@lists.unl.edu iversonlab@lists.unl.edu; Christina Carozza ccarozza2@huskers.unl.edu Subject: [Iversonlab] Pipete calibration

I am planning to line up pipette calibration for our lab next week. But I need to know how many pipettes we want to have calibrated. Can someone please count the number of single channel and multichannel pipettes that we have in the lab (and want calibrated) and let me know.

Also, do you want to have our balances recalibrated? If so, how many?

Please let me know as soon as possible so I can get our spot reserved.

Thanks!

Iverson
