Design of the AFIS. (a) Teflon water bottle (2.7 l volume); (b) syringe (hand syringe GENIUS 450 ml) with maximal volume of 300 ml; (c) bottle lids connected with closing devices on the CTD-bottle rosette; (d) adapter between syringe and bottle, coupled with a dispenser tube; (e) escapement for the syringe plunger, directly connected with the closing devices for the bottle lids. The operating mode is based on the following principles: (1) the syringe plunger is pushed by a spring; (2) the release of the spring is coupled with the closing devices for the bottle lids; (3) the solution passes through the dispenser tube into the bottle; (4) the dispenser tube extends from the top to the bottom of the bottle; (5) the solution is equally distributed through perforations of increasing diameters made in the dispenser tube.
