Pipette Calibration

[@ArnelgCartoneros]

Thank you so much sir your video got me also learn

[@Snow4LifeNEver]

The range should rather be 0,992g to 1,002g for 1,000mL at 20C. I would highly suggest a straight pipette when unloading as it is a more repeatable and precise technique. I would also add that it is important to make sure there is no air bubble in the tip or extra droplets on the tip.

[@artemgorev2361]

what does it mean "straight pipette"? Keep it vertically?

[@mariaph9700]

@@artemgorev2361 yes, draw liquid up vertically, dispensing at an 45deg angle relative to receiving flask.

[@ArnelgCartoneros]

Yes that exactly correct sir.

Looking everywhere for that piece of plastic to caliber the pipet... Don't find it! Was it in the pipet box when you bought it? Do I have to buy it? I'd like to calibrate my pipet myself

PIP 90 degree then pre wet once then dispense

[@rahmhadeel5570]

correct me ...... 1000 micron = one gram ???? is it right ?

[@paavobergmann4920]

microgram. A micron is a micrometer. a microgram of water at 20°C is 1 microliter.

[@profflowers]

@@paavobergmann4920 one microliter of water weighs approximately one milligram (not one microgram)

[@paavobergmann4920]

@@profflowers thats correct, sorry, I got confused.
