Brand Name : Crown

Application : Measurement

For the continuous production of electrostatic charges and high D.C. potentials in the laboratory. Two plastic disks of 300mm dia have a series of metal foil segments attached radially to them. These disks are contra-rotated by a simple hand operated belt drive. Induced charge built up on the foil segments as the disc rotates is picked up by the metallised cloth wipers rubbing against them and transferred to the discharge arms. Two Leyden jar capacitors can be linked via a simple moving contact to the discharge arms. These enable higher potentials to be obtained between the discharge arms. It produces sparks upto 50mm under appropriate conditions.

The main use of litmus is to test whether a solution is acidic or basic. Wet litmus paper can also be used to test for water-soluble gases that affect acidity or alkalinity; the gas dissolves in the water and the resulting solution colors the litmus paper. Red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 *C (77 *F). Pkg. of 100 leaves
