Inoculating Loops, Needles & Spreaders
These sterile disposable plastic loops and needles are designed for use in quantitative procedures such as sampling, urine counts and serial dilutions, as well as for bacterial inoculation. Because they are pre-sterilized and designed for single use, there is no risk of cross contamination and no need for flaming. They are flexible enough for streaking, yet rigid enough for subsurface inoculation.
The unique hexagonal shape of the shaft makes it easier to grip, orientate and guide through a smooth streaking process. The loop surfaces are extremely smooth with no rough edges and no flashing or burrs on the loop head. This results in the elimination of cutting or gouging of the agar surface.
Sterile, disposable and verifiably accurate, these loops provide an efficient, cost-effective and time-saving alternative to traditional metallic loops.
The MTC Bio line of bacteriological spreaders has been expanded to include four different shapes and sizes. In addition to the original L-shape, a similar T-shape version and two triangle shapes (large and small) are now available. All versions are supplied in sterile packaging, but are also and have smooth, rounded edges to prevent unwanted cutting, scraping or gouging of agar during inoculation.
L-Shape
The original spreaders are ideal for spreading bacteriological cultures evenly. The shape allows the user to rotate and apply easily throughout an entire round plate or dish. They are made of ABS and have a slight upward curve at the edge to prevent dragging or scraping.
T-Shape
This shape ensures that consistently even pressure can be applied across the entire span of the 34mm spreading surface. Designed for spreading and dispersing liquids across the surface of agar culture plates, they are made of ABS and commonly used for CFU plate counts on water, milk, urine, etc.
Triangle Shape
This new design is also used for CFU count applications, but has a grooved handle that improves grip and orientation. Made of polypropylene, they are available with a 30mm span or an extra large 60mm span.
