Figure 4. Flow-cell assembled and also showing some components.
(a) Assembled flow cell: 1) Top fitting for flow cell; 2) Upper horseshoe clamp for holding top fitting with flow-cell body; 3) Flow-cell central body; 4) Adjustable side-arm for the extraction of fluids and beads; 5) Lower horseshoe clamp for holding bottom fitting; 7) Adjustable valve for regulating flow and extraction of contents as well as allowing the upward flow of gasses such as N₂ through the complete assembly.
(b) Expanded view of selected parts of flow-cell: 1) Top fitting for flow-cell; 2) O-ring between top fitting and main flow-cell body; 3) Aluminium filter designed to contain alginate beads, but to allow for liquid and gaseous flow; 4) Adapter fitting for Leur-Loc® syringe; 5) Glass-to-steel intermediate adapter; 6) Fitting with ground-glass flanged surface to attach to the side-arm of the central flow-cell body; 7) Clamp for holding the fitting onto the side-arm; 8) View of horseshoe clamp with three tightening screws.
