Variable Angle Glass Prism, 5° x 5° x 170° Lab Supplies_Clips sized for low-resistance Ohm's-law work

sized for low-resistance Ohm's-law work where high-resistance components don't draw measurable current

the smallest in the bar-magnet series

5-inch needle-pointed stand grips a 3/4-inch-wide bar magnet upright for hands-free study of attraction

Fitted with independent air and gas adjustments plus a brass flame stabilizer tip

Large-wheel pulley mounted on a universal clamp for attachment to retort rods or support stands

Variable Angle Glass Prism, 5° x 5° x 170° Lab Supplies_Clips sized for low-resistance Ohm's-law workGlass prism with a 5 degree apex and 5 x 5 x 170 angles, the shallow apex producing minimal deviation for studying small angle approximation in dispersion experiments.
