Hypodermic Syringe Measurement


Syringe Volume Sizes

• 0.5 mL

• 1 mL

• 3 mL

• 5 mL

• 10 mL

• 20 mL

• 60 mL


Syringe Calibrations

• Regardless of syringe’s volume, calibrated in milliliters– Except specialized insulin syringes


How to Read a Syringe

• From top/front ring

• First long calibration always zero


3 mL Syringes

• Most common

• Should be calibrated using metric unit mL– Some still include calibrations in cubic centimeter (cc)

• Essentially identical to mL


3 mL Syringes


3 mL Syringes

• Shorter calibration marks indicate tenths of a mL

• Longer calibration marks indicate ½, 1, 1½, 2, 2½, and 3 mL

• Tenths of a mL written as decimal fractions– E.g., 0.1 mL, 0.6 mL, 0.9 mL


3 mL Syringes

• What is the volume of medication in the syringe?


Safety Syringes

• Developed to decrease risk of accidental, contaminated needle sticks

• Variety currently manufactured

• Most health care facilities use some brand

• Become familiar with type used in local clinical facility


Tuberculin (TB) Syringes

• Most common volume 1 mL

• Calibrated in hundredths– Noted by shorter calibration marks

• Each tenth calibration mark has Arabic number printed on syringe barrel– E.g., .1, .2, .3, etc.

– Noted by longer calibration marks


TB Syringes


Larger Volume Syringes

• Most common:– 5 mL

– 10 mL

– 20 mL

– 60 mL


Large Volume Syringes

• Shorter calibration marks located on 5 mL and 10 mL syringes measure 0.2 mL

• Longer calibration marks measure 1 mL


5 mL Syringe


10 mL Syringe
