Here is the problem.....1 ml easy touch luer locks are not insulin syringes.
Most commonly used insulin syringes come with a fixed needle (low dead space).
Using a fixed needle (low dead space).....let alone drawing/injecting using the same needle results in minimal waste of medication.
“Fixed insulin type syringes have no void space at the point where the needle joins the syringe, and so are known as Low Dead Space Syringes, which is sometimes abbreviated in the literature to LDSS. They are made like this so that the full accurate dose is delivered, and there is no waste”
Insulin syringes are meant to be used to draw/inject insulin (water based).....although we very well know that they can and are used to draw/inject esterified T (oil based).....let alone other water based medications.
Commonly used insulin syringes come in 27-31 gauge with various needle lengths 15/64" (6mm), 5/16" (8 mm), 1/2" (12.7 mm).

Needle and syringe designs that affect dead space. a Standard (high dead space) syringe with standard needle. Average dead space (99 μL). b Low dead space syringe with permanently attached needle. Average dead space (3 μL). c Standard syringe with low dead space needle. No needle and syringe programs sent us low dead space needles (c) or a low dead space syringe (d) with a standard needle. However, use of both of these has become more common. We obtained samples of c and d from the manufacturers: c Covidien and d Henke-Sass
