What does the ‘s’ Mean on a 22s needle?

Note: The ‘s’ on a 22s needle represents a smaller I.D. (inner diameter) for the needle and a thicker needle wall for better durability. For example, a 26 gauge needle has an O.D. (outer diameter) of 0.46 mm and an I.D. of 0.26 mm while the 26s gauge needle has an O.D. of 0.47 mm and an I.D. of 0.13 mm.

What is the difference between cemented needle terminations and special needle terminations?

For low volume syringes the special needle terminations are the same as the Cemented Needle terminations except they allow for a variety of user-defined gauges, lengths and point styles to be attached. For mid volume syringes the needles are cemented into the glass syringe barrel at a point corresponding to the zero graduation mark.

How do I choose a needle gauge?

Refer to the needle gauge chart to choose a needle gauge with an appropriate µL/inch before selecting a needle. Select the minimum needle length that allows you to carry out your application comfortably. Note: The ‘s’ on a 22s needle represents a smaller I.D. (inner diameter) for the needle and a thicker needle wall for better durability.
