The Hartman Speculum (4.5mm, 35mm Oval, Size 1) is an otologic instrument designed for ear canal examination and access during diagnostic or surgical procedures. The size 1 speculum is particularly suitable for smaller ear canals, such as those in children or for more delicate procedures. The 4.5mm width and 35mm length offer precise control, while the oval shape ensures a secure, comfortable fit in the ear canal.
