nano 4 mm.
The smallest, thinnest needle is the nano 4 mm, 32 gauge needle, which is about as thin as two strands of hair.
Which gauge needle is thinner?
Needle Measurement
Gauge: The diameter, or thickness, of the needle. The higher the number, the finer or thinner the needle. For example, a 30-gauge needle is smaller than a 27-gauge needle.
Is a 21 or 25 gauge needle bigger?
The needle gauge becomes a consideration when the vein of the patient is narrow, fragile, or superficial. In such cases, a gauge size with a LARGER number (eg, 25 G) may be preferred over a routine needle gauge (eg, 21 G) to minimize damage to the blood vessel, as well as minimize the associated pain with collection.
Does a 21 gauge needle hurt?
Results: Twenty-one participants verbally reported the thinnest needle (27 gauge (G)) as least painful, compared to the intermediate (23 gauge; p = 0.013) and the thickest needle (21 gauge, p = 0.004).
Which of these needles is smallest?
Needles in common medical use range from 7 gauge (the largest) to 33 (the smallest).
What is a 23G needle?
23G hypodermic needles and steel adapters are commonly used with tubings to inject or extract liquid samples. They are described by gauge numbers indicating outer diameters (OD). Among those values, the 23-gauge (23G) is a standard in both Medical and Microfluidic fields.
How thick is a 24 gauge needle?

What is a 26 gauge needle used for?
These are regular-walled medical point needles. They are for intramuscular, subcutaneous, and other injections and are available in a wide range of gauges and lengths. They have an oversized chrome plated luer lock hub.
Do smaller needles hurt less?
In conclusion, smaller needles can reduce pain and provide other advantages that can increase patient compliance.
What is smaller 23 or 25 gauge needle?
The gauge size of a needle indicates what the diameter of the lumen (opening) is. The higher the gauge, the smaller the diameter.
Plastic (Straight 0.25?, 0.5?, or 1.0?)
| Gauge Size | Inner Diameter (mm) | Color |
|---|---|---|
| 23 | 0.330 | Orange |
| 24 | 0.300 | Blue-Green |
| 25 | 0.250 | Red |
| 26 | 0.240 | Peach |
What are 22 gauge needles used for?
The needle size is important for precise injection. A 22-gauge 3.8-cm (1.5 in.) needle is used for superficial muscles. When capillary fragility with bleeding is a concern, a thinner 25-gauge needle may be preferred.
What size is a subcutaneous needle?
Subcutaneous (Subcut) injections
Inject at a 45° angle into fatty tissue overlying the triceps muscle a ?” needle, 2325 gauge is recommended.
How thin is a vaccine needle?
Most adolescents and adults will require a 1- to 1.5-inch (2538 mm) needle to ensure intramuscular administration.
What size are diabetic needles?
The standard needle is 1/2-inch long. Needles also come in 5/16-inch and 3/16-inch lengths. The 3/16-inch length is often used for children. The thinner the needle, the higher its gauge.
What is a 30g needle used for?
The 30-gauge needle is not recommended for supraperiosteal or block injections, but can be useful for localized infiltration (injecting the papillae, for example, to obtain hemostasis).
What is smaller 18g or 22G needle?
IV needles are sized by gauges, and the smaller the gauge number, the bigger the needle will be.Nevertheless, 18, 20, and 22 gauge is the size you’ll encounter most frequently in most areas of nursing.
What is a 25G needle used for?
The length of a needle is listed after the gauge number. For example, 25G ? refers to a 25 gauge, ? inch-long needle. Longer needles (? inch or longer) are commonly used for intramuscular injections, while shorter (shorter than ? inch) needles are more often used for intravenous injections.
How big is a 21 gauge needle?
Needle gauge table
| Needle gauge | Outer diameter (inches) | Inner diameter (mm) |
|---|---|---|
| 21 | 0.03225 | 0.514 |
| 22 | 0.02825 | 0.413 |
| 22s | 0.02825 | 0.152 |
| 23 | 0.02525 | 0.337 |
What size is a butterfly needle?
Typically, butterfly needle gauge sizes range from 18 to 27, with higher numbers representing thinner needles with smaller bores. The length of a standard butterfly needle is 3/4 inch.
How big is a 10g needle?
2.588 mm
| gauge | inches decimal | millimeters |
|---|---|---|
| 10g | 0.102″ | 2.588 mm |
| 0.125″ | 3.175 mm | |
| 8g | 0.129″ | 3.264 mm |
| 6g | 0.162″ | 4.115 mm |
Do smaller needles hurt more?
The needle’s width, known technically as the gauge, has a lot do with how uncomfortable it feels when it pierces your skin. Not surprisingly, the narrower the needle (which, ironically, means it has a larger gauge number), the less it hurts.
