Question: 1. what is the difference between macrodrip and microdrip tubing?
Answer: Macrodrip tubing comes in 3 sizes: 10 gtt/mL, 15 gtt/mL, and 20 gtt/mL. (Note: 10 gtt/mL, for example, means 10 gtt = 1mL.) Microdrip tubing is narrower and so produces smaller drops. ... Microdrip tubing (sometimes called minidrip) comes in only one size: 60 gtt/mL.
