Table 2.
Loading times of ceramics as a function of the different alginate concentration and pressure difference applied to the flow chamber (N = 10).
| Concentration (%w/v) | Loading Time (min) | ||||
|---|---|---|---|---|---|
| 500 mbar | 250 mbar | 100 mbar | 50 mbar | 5 mbar | |
| 1 | 42.8 ± 19.0 | 28.3 ± 16.5 | 12.1 ± 3,8 | 5.4 ± 0.3 | * |
| 2.5 | 112.6 ± 14.5 | 47.0 ± 12.1 | 25.3 ± 10.5 | 10.0 ± 3.1 | * |
| 5 | >120 | >120 | >120 | >120 | * |
* At this pressure the hydrogel began to freeze within the flow chamber, making loading impossible. After loading process the alginate was crosslinked in 30 mM CaCl2 solution
