- An untreated, non-indicating cellulose filter paper card designed for the simple, routine collection, short-term handling, and transport of blood and bodily fluids
Uses
- Routine Sample Collection:
- Ideal for collecting, drying, and transporting small volumes of whole blood and other bodily fluids
- Protein & Small-Molecule Analysis:
- Suited for workflows that require the recovery of proteins or small molecules without chemical interference
- General Research:
- Used across various routine clinical, forensic, and biological research applications
Features
- Untreated Cellulose Matrix:
- Plain cellulose captures samples through physical absorption rather than chemical bonding
- Multi-Spot Format:
- Each card contains 4 distinct sample collection areas
- High Capacity:
- Each designated sample area or "spot" accommodates approximately 125μL of fluid
- Protective Cover:
- Each card is equipped with an attached paper flap/cover to shield the dried specimen from contamination
- Non-Indicating:
- The paper does not contain dyes that change color upon fluid application
Benefits
- Room-Temperature Transport:
- Eliminates the need for cold chain logistics (freezers or dry ice); samples can be shipped via standard postal services
- Chemically Unmodified:
- Leaves the collected sample completely free of added collection chemicals, which prevents interference during specific downstream extractions
- Easy Processing:
- Punches easily with standard tools to retrieve the cutout piece of the paper matrix for analysis
- Convenient Storage:
- Allows collected samples to easily travel from the field to the laboratory
