Rheoscopic Fluid Concentrate Plastic Labware_Plastic Wash Bottles sized for two-cell battery-pack circuits

sized for two-cell battery-pack circuits and the standard ray-box and panel-lamp apparatus

supplying the standard short-reach patch wire for student-built 4mm-socket circuits at the bench

sized for routing around components and through apparatus where solid-core wire would be too stiff to follow the bend

sized to detect bidirectional currents stronger than the milliampere-class meters can read
