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 autoclavable and have smooth, rounded edges to prevent unwanted cutting, scraping or gouging of agar during inoculation.
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.
