The Endo-pap sampler is an elongated sampling device constructed from polypropylene. It has an easy to grip handle and an elongated, small-diameter sampling probe. The probe consists of six collecting cusps situated adjacent to the end of the probe.

The cusps / grooves have a scraping edge formed by the peripheral surface of the probe and a sidewall intersecting the peripheral surface at an acute angle. This unique collector design minimises contamination by cervical cells on withdrawal. Due to polypropylene being a soft, flexible plastic, one is able to pre-shape the sampling device to conform to the uterine position. The samplers are packaged as singles in a sterile peel pouch.
