Hypodermic Syringe Measurement

2. Syringe Volume Sizes
0.5 mL
1 mL
3 mL
5 mL
10 mL
20 mL
60 mL

3. Syringe Calibrations
Regardless of syringe’s volume, syringes are calibrated in milliliters.
Except specialized insulin syringes

4. How to Read a Syringe From top/front ring
First long calibration always zero

5. 3 mL Syringes Most common Should be calibrated using metric unit mL
Some still include calibrations in cubic centimeter (cc)
Essentially identical to mL

7. 3 mL Syringes (cont’d)
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:
For example, 0.1 mL, 0.6 mL, 0.9 mL

12. Safety Syringes
Developed to decrease risk of accidental, contaminated needle sticks.
Variety currently manufactured.
Most health-care facilities use one brand.
Become familiar with type used in local clinical facility.

13. Tuberculin (TB) Syringes
Most common volume is 1 mL
Calibrated in hundredths
Noted by shorter calibration marks
Each tenth calibration mark has Arabic number printed on syringe barrel.
For example, .1, .2, .3, etc.
Noted by longer calibration marks
