    Coated with PTFE, these stirring bars are corrosion and chemical resistant. Some are available in different colors for easy identification.
    Octagon—Octagonal stirring bars are the most commonly used shape. They have a large surface area to generate more turbulence than round bars, so they stir up particles for better mixing.
    Polygon—Polygonal stirring bars spin smoothly like round bars, but also generate turbulence for mixing particles, such as salts, into solutions. Select the large ODs for jobs in drums or tanks.
    Capsule—Capsule stirring bars are sized just right for small containers, such as vials, tubes, and gradient makers.
    Oval—Oval stirring bars work best with round-bottom flasks.
    Triangle—Triangular stirring bars are designed to fit small vials. Use the 3/16” wide bars for 1 mL vials and the 3/8” wide bars for 3-5 mL vials.
    Cylinder—Cylinder stirring bars spin more smoothly than octagonal bars.

    304 Stainless Steel

    Paddles without Holes

    Mix and stir food and other material in hygienic environments with these paddles—they’re easy to clean and won’t corrode from frequent washdowns with harsh cleaners. You can also use them as scrapers.
    Polypropylene—Polypropylene paddles are much lighter than stainless steel paddles, which reduces fatigue during extended use. They also have a T-handle to give you more comfort and control. They’re often used to mix soups, sauces, and powders. Unlike stainless steel, they won’t scratch surfaces. Constructed from a single piece of plastic, they have no seams where bacteria can grow. These paddles are FDA compliant for direct contact with food.
    304 Stainless Steel—304 stainless steel paddles are more durable than plastic paddles, and won’t bend or chip with prolonged use. They’re often used with dense or heavy materials, such as sticky dough and ice cream. These paddles are highly polished and have smooth, continuously welded seams, so bacteria has nowhere to hide. They meet NSF/ANSI 2 design standards for sanitary food equipment.
    Paddles with Holes—Paddles with holes are good for agitating liquids, and they help break up clumps in your mixture.
