I use 3/10 cc/ml U-40 syringes, that we started with for ProZinc. Each syringe holds 12 units, marked off in 1 unit increments.
I received from DCIN U-40 syringes that are 1/2 cc/ml and hold 20 units. They are marked 5, 10, 15 and 20 with 5 marks between.
What I want to know is on the 1/2cc/ml syringes is each mark 1 unit? I want to use these but want to be sure that is correct. The barrel looks so much bigger on the 1/2 cc syringe than the 3/10 cc syringe.
Thanks
 
yes the u 40's are always exactly what they say they are. 1 unit on one is 1 unit on a different size syringe. I know they look different, i think it is because of the interior wall or something...but trust the syringe...it is always the same.
