Tailor-made infrastructure for the controlled injection of prefilled syringes (PFS) into tissue samples

•  Easy sample change

•  Controlled positioning of the syringe needle

•  Controlled injection

•  Force-displacement measurement during the injection process

•  Force switch-off to protect the syringe

•  CE conformity

•  Linear unit for positioning the syringe needle with 150 mm travel

•  Injection motor with 40 mm travel

•  Linear table with micrometer screw for precise positioning of the needle above the sample

•  3D-printed base holder for holding a wide variety of syringe types

•  3D-printed aluminium heat sink for cooling the injection motor

•  Magnetic linear spring to prevent unintentional lowering of the injection motor rotor

•  Development of the control software

•  Setting up and commissioning the hardware and software

•  Testing different injection speeds

•  Calibrating the force-displacement measurement

•  Injection tests in tissue samples

•  Setting up the injection setup on the beamline

•  Carrying out the customer-specific experiments
