Specifications

What Is the 21G Disposable Needle Used For?

The 21G x 1 1/2 inch needle is a middle-of-the-range size: wider than 23G, finer than 19G, and at 40 mm long it is the longer of the two needle sizes listed with a length. Clinicians commonly reach for this size for general injections and for withdrawing blood or other fluids, pairing it with 5 ml, 10 ml or 20 ml syringes. As always, gauge and length are chosen by the treating professional for each patient and procedure.

The coloured base is a practical safety feature on a busy trolley: staff can confirm the size at a glance without reading the small print on the pack. In nursing and phlebotomy training, the 21G needle is widely used to demonstrate attaching a needle, removing the cap safely and disposing of sharps. Institutions that order from a lab consumables supplier in India usually keep it in stock beside the 19G and 23G sizes.
