Figure 5.

Lab-In-Syringe system from a syringe pump (SP) with nine port head valve (HV) with an upside-down orientated syringe (S). 3D printed elements are shown in blue color and disassembled, required screws are not shown. The syringe is situated on a laboratory stand compatible support (1). On the head valve, SLA-printed elements add the functionalities of a flow-through port (2) and connecting a drain tube to waste as well as air aspiration (3), respectively. Elements 4 allow mounting further elements on the head valve, here a support (5) for positioning and leveling of the stirring motor (M). The motor is equipped with a pulley-wheel (6, photography below) connecting the motor via a rubber band to a simple stir-driver (7, photograph above) that is held in place by a supporting ring (8).
