This sturdy electroscope features a metal case with front and rear glass windows for preventing air currents from affecting the deflection of the leaves. Leaves are gold and aluminum.

Spark timer is used for measuring velocity and acceleration of falling or moving objects. When the tape is pulled through the timer a spark is created which burns tiny dots in the tape at a precise and same interval.

These uncalibrated specific gravity bottles are excellent for determining the specific gravity of liquids. The borosilicate bottles have a ground stopper joint for a precision fit. Available in 10 ML or 25 ML sizes.
