Disposable Spreaders

Spread cultures and liquids evenly
Smooth-edges – minimize “gouging”
3 configurations: “L”, “T”, or Triangle
Ideal for bacterial CFU Counts
Pre-sterilized – no flaming required

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.

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 34 mm 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 30 mm span or an extra large 60 mm span.
