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 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.
