Whatman is a market leading manufacturer of sample collection and preparation products which serve a variety of markets. Whatman has a long history of developing cutting-edge products that meet the needs of today’s genetic analysis laboratories.
The collection of DNA samples for genetic analysis has evolved to meet current needs. Blood samples have always provided high yields of DNA for a number of genetic tests. However the invasive nature of blood collection has caused laboratories to look for alternative methods. Buccal epithelial cell collection is a preferable substitute for blood collection due to the noninvasive method of obtaining samples. A simple rubbing of the inside of the cheek with a mildly abrasive surface is adequate to collect cells for genetic analysis. Buccal cell collection using foam tipped applicator swabs and FTA Cards is an accepted method used by forensic laboratories worldwide.

EasiCollect™ features a novel foam applicator for the adsorption of cells to its surface and for maximal cell transfer. Dual clips on the handle and on the front of the device apply constant pressure of the foam applicator to the collection card. Cells are applied across the sample area in a consistent manner ensuring amplifiable DNA in all locations.
The indicating FTA material inside the device contains an inert dye that changes color upon application of a colorless sample to indicate the location of the sample area. Individual sample punches are taken from within the sample area for DNA purification and amplification.
