A device for collecting biological material is disclosed. The device comprises a shaft with a loop-like collection means at one end. The collection means provides a non-cutting, scraping edge to allow collection of the material without cutting. In a preferred embodiment, the collection means retains the material by diverting it into the interior portion of the collection means. The biological material is released from the device by rotation of the shaft or by elution in an appropriate solvent. |
