Narrow-Angle Glass Prism, 10° x 85° x 85° Capacity_50mL this two-gap Wheatstone bridge is

this two-gap Wheatstone bridge is the standard student apparatus for resistance comparison and verification

sized for classroom balance experiments and physics mass demonstrations

3 glass Griffin-form beaker shot glasses hold 3

Used for heavy-gauge coil construction and electromagnet windings

the broader apex producing larger deviation for direct comparison against the narrower wedges in the angle-series set

Narrow-Angle Glass Prism, 10° x 85° x 85° Capacity_50mL this two-gap Wheatstone bridge isPairs a 10 apex with 85 x 85 base angles on a glass wedge prism, the slightly wider apex stepping deviation up from the 5 wedge while keeping the thin prism form factor.
