Low Dead Space Syringes Available

Feb 19, 2012

A Low Dead space syringe is a type of syringe designed to limit the amount of dead space that exists between the syringe hub and needle and reduces the amount of “wasted” medication with each injection. Syringe dead space is the volume of residual fluid that remains within the syringe after the plunger is fully depressed during medication injection. The difference between “High Dead Space” or a standard syringe, and a “Low Dead Space” syringe is determined by the amount of fluid that remains within the needle and syringe itself. When a patient is injecting his/her prescribed medications multiple times per week, the amount of “waste” can add up significantly. More medication can be lost when a new needle is attached for injection purposes. Dead space in a standard syringe can be as high as 84 micro liters with each injection. This can also introduce the problem of inaccurate dosing, especially when prescribed smaller, more frequent injections of your prescribed medication.


With a typical wastage of 84uL (microliter = 0.084mL) per injection, a patient injecting 0.35ml of testosterone twice weekly should expect about 28 injections per 10mL of Testosterone Cypionate.

28 injections X 0.084mL wastage per injection = 2.35ml of wastage per 10mL vial.


28 injections X 0.002mL wastage LOW DEAD SPACE = 0.56mL of wastage per 10mL vial.
See picture above

To better assist our patients and provide the most accurate needle and syringe options for administering medications, Defy Medical is now offering a more precise, low dead space 1mL Luer Lock syringe. These syringes can be used for injecting testosterone, HCG and injectable vitamins/amino acids.
