Free Fall Apparatus ‘g’ Economy with Timer
The determination of the gravitational constant ‘g’ is one of the most fundamental and early physical constants students must derive and observe. This kit has a wooden base, 1.1m rod and a movable electromagnet. The electromagnet can be moved anywhere on the rod and is powered by the timer. When the ball is released, the timer is triggered and stopped once the ball has landed on the base for a precise measurement and then calculation of ‘g’. Supplied with manual.

Pascal's Law Apparatus
Mounted on molded plastic base, the unit consists of a base into the top of which may be screwed one of a set of four vases of differing shapes. An aperture in the bottom has a thin rubber diaphragm across it, bearing upon the short arm of the lever pointer. A moveable index on the vertical rod enables the height of water in vases to be set at same level. The apparatus is mounted on moulded plastic base that measures 25 x 17.5cm. The experiment is performed by screwing in each vase, in turn, and filling with water to the same level. It will be seen that the given height of water will result in the same deflection of pointer whatever shape of the vase.

Autoclavable Test Tube Racks
A space saving alternative to wire racks, these stackable submersible plastic racks are constructed of a special blend of autoclavable polypropylene. This mold-resistant plastic is both safe and sterile for use in the lab. The white racks will sink in a water bath and maintain their stability even in agitated water. Each rack features end plates for labeling as well as numbered and lettered rows for tube identification. Size of each: 9 3/4" x 4 1/10" x 2 1/2".
