Thread: Why did my homebrew result in less oil than anticipated?

Research +\- variations and accuracy of syringes and graduated cylinders.

You can take a 1ml slin pin, fill up a 10ml syringe 1ml at a time, and see the discrepancies.
You can take a 10ml syringe and put it in a 60ml syringe and same thing, it will be off.
Graduated cylinders have grades of accuracy.
They will have +/- markings such as +/- 1ml.

My last brew of Tren E, 120ml, lost around 7ml.
Some left in beaker, some left in filter, some left in media bottle, some drippage when filling sealed vials using 60ml syringe.
