Lead Rods for Thermal Conductivity Experiments, 10-Pack Lab Supplies_Brushes this metal-framed bench demonstration board

this metal-framed bench demonstration board uses variable resistors and switchable inputs to show how a meter measures V

wheel-and-axle

sized for resistivity experiments and rheostat construction where small-cross-section copper-nickel is required

this single burette clamp in powder-coated alloy holds any burette up to 100 mL on support rods up to 16 mm diameter during titration work

sized for measuring direction and field strength on the lab bench
