sterile inoculating needles rigid polystyrene peel wrapped 50 bags of 20 needles 1000 cs

Sterile disposable rigid plastic loops and needles allow for more precise streaking patterns on agar plates. Because they are pre-sterilized and designed for single use, there is no risk of cross contamination and no need for flaming. The unique hexagonal shape of the shaft makes it easier to grip, orientate and guide through a smooth streaking process.
