    To Arnab Goswami: Not sure if you will see my message, but I have a HOT NEWS JUST FROM THE OVEN. 600 Crore CORRUPTION CASE AGAINST Pappu's MOM Sonia Gandhi and 2013 CONGRESS GOVT. This is related to Augusta Westland Helicopter Purchase. The news is just coming out. I'm not sure how many of our LEFT WOKE media will PUBLISH this news as they are all bought by George Soros and Pappu Family. Milan Court has just Declassified the document and you will be shocked to hear the names including Manmohan Singh, Sonia Gandhi the main person, Oscar Fernandez, Ahmed Patel, corngress govt.'s NSA M K Narayanan. Sonia Gandhi's 600 crore is lying in Mauritius now. So far to my knowledge only one channel in India has published this news. Why are you quiet ? Come on , Act Fast!!

    In the late 90s we had a contract with Hoechst Celanese in Dallas. We fumbled through it with "Ho-chest", but oddly, the representatives at the company called themselves "Hoke Celanese".

    2:24 I do that with my thumb and a pipette head sometimes, the only probelm is that in microbiology it means you have to rinse the thumb with ethanol beforehand and afterwards to kill the possible hitchikers c: for the record, yes, I too wear gloves when doing that :D

    THANK YOU oh my god I'm trying to calibrate some Eppendorfs and every video on 'how to calibrate your Eppendorf pipette' just looks at how to see if it's accurate, not how to actually *calibrate* it. I was stuck with a disassembled pipette & an old manual trying to figure out if maybe I just need to send it away. This is finally answered my questions!!

    • @dinornis
      @dinornis Před 2 lety

      Whelp, I've now read about calibration vs. adjustment, and those other videos were accurate in that they *did* provide calibration information - calibration is what happens before adjustment! But video was still super helpful regardless!

    This is wrong on so many levels. The initial size of the dish doesn't matter. Confluence is a subjective take on density. You need a hemocytometer to get the actual density and go from there.
