The MTC Bio M5441 Triangle Shape Spreader, 60 x 235mm, is supplied in sterile packaging, but is also autoclavable and has smooth, rounded edges to prevent unwanted cutting, scraping or gouging of agar during inoculation. The triangle shape design is used for CFU count applications, but has a grooved handle that improves grip and orientation. Made of polypropylene, the spreaders have an extra large 60mm span.
