Use these general-purpose samplers for mixing, stirring, and collecting specimens. Wood spatulas are made from close-grained, northern white birch for a smooth, splinter-free finish. Spatulas have no taste or odor—perfect for spreading, stirring, and mixing food samples. Cotton swabs feature an oversized cotton tip. Cotton is carded and spun, then bonded securely to a wood shaft. Rayon swabs have tips made of the finest USP grade of rayon fiber. These swabs are available with either a wood or plastic shaft.
