| + | 124 | * '''Permanently attached needle.''' The cannula is moulded into the barrel and the plunger tip advances to its proximal end. This achieves the lowest values, of the order of 2–6 µL, and is the standard construction for insulin syringes. | |
| + | 125 | * '''Hub insert.''' A moulded plastic plug fills most of a standard Luer hub, leaving a channel for liquid, so that a conventional detachable-needle syringe achieves roughly 10 µL. The needle remains detachable, which preserves the operational flexibility of a Luer fitting. | |
| + | 126 | * '''Extended plunger tip.''' The plunger tip carries a projection that enters the hub. Values are intermediate and depend on the fit achieved. | |
