The Cohen Cone Only, Tip Length 25 mm is a stainless steel Cohen Cone Only with a 25 mm tip length. The "cone only" term suggests this is a modular or detachable component, possibly part of a larger system. Other variants of Cohen-style instruments exist, including those with cones of different sizes. For example, an intrauterine probe by Cohen is available with a 25.0 mm cone, and the Cohen cannula is offered with 19 mm or 25 mm working end sizes.
