    The Sampling Device

    The Roversre® Cervex-Brush® Combi will collect both Ectocervical and Endocervical cells from patients. The Rovers® Cervex-Brush® Combi is a newly patented, high tech product capable of delivering higher cellular yield of endocervical cells than the traditional Rovers® Cervex-Brush® . Laboratory tests have also indicated an increased viral load in the collected cell material. The Rovers® Cervex-Brush® Combi was developed for two main reasons: Easy and effective application of the device. Improved endocervical sampling.

    A Two in one brush

    It’s a combination of Cervibroom and Cytobrush which is used in both Thin Prep and Sure Path. Its Delicate for using.

    The Rovers® Cervex-Brush® Combi was developed for two main reasons

    • Easy and effective application of the device.
    • Improved endocervical sampling


    Besides the advantages of the Rovers® Cervex Brush® and the Rovers® endocervical amplers, the new Rovers® Cervex-Brush® Combi offers the following features
