• Uniform sample absorption
• Ease of punching with minimal force
• Minimal fiber shedding upon punching (limited carry over)

Proven for collection of blood, urine, and other bio samples. The flexibility in design enables use in research, laboratory, and field-based applications. With no need for pre-treatment of the cellulose matrix, DBS products are particularly suited for small-molecule and protein analysis work flows
