Description
Sterican® disposable needles, 21G x 40 mm are single-use cannulas for laboratory liquid-handling duties and syringe-accessory applications. They feature a 21-gauge needle, a 40 mm length, and a long bevel facet suited to controlled aspiration and dispensing steps. The hub is green, enabling rapid visual gauge identification whenever multiple needle sizes are present. Packs contain 100 pieces with a pack weight of 0,110 kg, supporting straightforward stock control. These needles from manufacturer B. Braun sit within the Sterican® disposable cannula line used across labware and liquid-handling setups. The long bevel facet geometry specified for this size helps operators keep a uniform penetration profile during vessel access and liquid transfer. Green colour coding further reduces selection errors at busy workstations. Supplied in a 100-unit pack, the 21G x 40 mm format suits laboratories that standardise on disposable needles for routine cannula work. Teams can distribute the pack across several stations while maintaining consistent gauge, length, bevel style, and hub colour for everyday syringes-and-accessories workflows.
This article is part of Needles & cannulas, in Syringes & needles.

Questions about Sterican® disposable needles, 21G x 40mm, Green, long bevel facet, 100 unit(s)
What is this article?
Sterican® disposable needles, 21G x 40mm, Green, long bevel facet, 100 unit(s) is the article on this page. Luminix Health distributes B. Braun for laboratory use. It sits in Needles & cannulas, inside Syringes & needles, in Lab consumables.
A needle or a cannula is specified by gauge, length and point, and by how it connects, Luer or cemented. A blunt needle is for transfer. A sharp needle is for piercing. Gauge is the outer diameter: a higher gauge is a thinner needle. The fitting has to match the syringe.
A syringe is a barrel and a piston. A disposable syringe is for transfer and injection. A microlitre syringe is a precise analytical tool, often with a cemented or removable needle, used to inject into a chromatograph. The needle gauge and the point, and the Luer or cemented connection, have to match the job. A Luer slip and a Luer lock are not the same fitting. In-vitro and diagnostic context is under ISO in vitro diagnostic systems.
