This C-clip Bottoming Tool offers a precise and efficient method for securely seating C-clips at the tip of a clipping tool's barrel, a crucial step prior to grid clipping. Designed to enhance your cryo-electron microscopy workflow, this tool simplifies the process significantly. Instead of manually pressing the barrel against a surface, users simply place the clipping tool's barrel into the Bottoming Tool's cylinder and press the plunger. The tool's cylindrical design ensures the clipping tool barrel remains perfectly straight, which is essential for proper C-clip alignment and secure seating. This innovative approach effectively minimizes the risk of mis-bottoming C-clips or, crucially, preventing them from flying out and being lost. By providing an easy and dependable way to prepare C-clips, this bottoming tool contributes to increased accuracy and reduced material waste in delicate cryo-sample preparation.
