When should you choose it?

Sample application


Thin and light, suitable for small volume lateral flow applications.
Medium weight ensures test-to-test reproducibility.
Thick material suitable for high sample volume.

Conjugate release

STD 14
Fusion 5

Light, thin glass fiber: suitable for small volumes.
Single layer matrix membrane that can be used to replace traditional modular components from a lateral flow testing kit.

Blood separation


Bound glass fiber filter, especially suitable for saliva samples.
Bound glass fiber filter suitable for serum samples and even one drop of whole blood.
Bound glass fiber filter suitable for serum and whole blood samples (ca. 100 μl).
Can be used as a vertical separator, as single or multiple layers, for separation of a wide range of blood volumes.
