How much device to send

Extraction ratios and per-test volumes from ISO 10993-12. Cut-and-share pooling means the program total is usually far less than the sum of the individual tests.

Material form

Sets the surface-area to extractant-volume ratio.

Size of one device

cm²

Patient-contacting surface area, or mass for membrane and powder forms.

Options

The device can be cut and shared between tests Reusable — test as-manufactured and end-of-life Add a 15% overage buffer Chemistry in triplicate
