Semicircular Acrylic Block, 90 x 16mm Lab Supplies_Spring Scales Two independent output channels on

Two independent output channels on this compact AC/DC power supply deliver six selectable voltages up to 12V at 500 mA each

Single-degree graduations and a non-magnetic plastic case allow this 100mm tangent compass to mount on any tangent galvanometer for precise direction-and-deflection readings

accepting any weights to plot force-versus-extension data on linear relationships

Open-top cylindrical dropping funnel in borosilicate glass holds 1000mL with PTFE key stopcock for large-volume controlled liquid addition

and harmonic frequency relationships
