Is this how it supposed to be?

Just grabbed the syringe with the pink tip and tested using RODI. Air pocket is ~.2ml:

I then weighed the water in a beaker on a calibrated scale. I tested 3 times: .97g, 1.00g, 1.00g:

The question still remains why can some draw up that syringe with virtually no air pocket at all and others draw it up with .25 air pocket somebody’s got to be right and wrong and I assume the ones with the bigger air pocket is wrong. And with that being said I guess I’m wrong in assuming 1 mL of fluid being required should actually get 1 mL of fluid. And it’s not my fault that in this world the manufacturer has to put in the directions information for the people who Have a hard time drawing up a syringe without air and I’m sure the manufacturer did not want to answer all these questions so they give a percentage or a margin of error and say it’s OK

The directions dont state 1ml of fluid. Just states to pull back to the 1ml line.

Does it really matter how much air there is if you aren’t using the entire fluid ?
The bottom of the plunger at 1.0 will still be the accurate reading

With the plunger at the 1ml line it is exactly 1ml of fluid.

If you include the volume of the pink tip .
but that’s calibrated with the fluid level at .85 ( .15 air

Agreed. But Mr. Ford thinks that fluid at the 1ml mark means 1ml of fluid and thats not correct in this instance.

I did state that I don’t use the pink tip and that may be the difference in the air pocket

I stand corrected. I thought it read 1 mL of fluid I apologize to everyone That I might have possibly inconvenienced
