The products Pirol and Skua from the company Greggersen are designed for a securely controlled aspiration of body fluids in hospitals and office based physicians. The product Pirol is driven by vacuum whereby Skua uses the Venturi principle to create vacuum. Both use several carry-over parts build of high-quality aluminum and plastic, which can be recycled very well. Their clean shapes and precisely flush transitions between parts created a convincing appearance as well as easily cleaning. The consistent application of corporate product design to the products Pirol and Skua help uniquely identifies the brand Greggersen.
