Breckland Scientific 2023 Catalogue
1 FRICTION RODS A range of friction rods made from various materials, for rubbing/charging with different cloths to investigate the electrostatic charge properties of materials. All rods are round and approx. 300mm long x 12mm diameter. Cat No. Description Price Per ECT-250-100 Ebonite-Brass Friction Rod 3.95 ea. ECT-250-150 Perspex Friction Rod 4.33 ea. ECT-250-200 Ebonite Friction Rod 2.32 ea. ECT-250-250 Glass-Brass Friction Rod 3.38 ea. ECT-250-300 Glass Friction Rod 1.46 ea. ECT-250-350 Nylon Friction Rod 2.90 ea.
2 ELECTROSTATIC CELL An hermetically sealed acrylic case, containing polystyrene tiny balls. When the upper part is rubbed for a long time with a cloth, the electrostaic
charge generated makes the balls move, demonstrating the action among charges. Cat No. Description
ECT-130-100 Electrostatic Cell
GOLD LEAF ELECTROSCOPE The CLASSIC ’Malvern’ type gold leaf electroscope. Housed in a rectangular sheet metal case mounted on a insulated base and provided with removable front and back sliding glass panels, one clear and other ground, respectively. Removable disc electrode mounted at the top through a moulded plastic bush insulating the disc electrode from the metal body to prevent charge leakage. The plastic bush has a plated metal blade on the underside for fixing the gold leaf. Case fitted with terminal at the side for earthing. Removable clear front slides up to allow insertion of ionising material in chamber and fixing of leaves, when needed. A clear acrylic circular scale inside the chamber, graduated 0-90° facilitates the comparison of charge by means of deflection. Supplied complete with one pair of leaves. Cat No. Description Price Per 3 ECT-100-100 Gold Leaf Electroscope 24.87 ea. 4 ECT-100-150 Gold Leaf for Electroscope 12.98 6pk 5 ZINC PLATE A 50 x 50 mm Zinc Plate which can simply be placed on top of an existing electroscope plate to allow demonstration of the Photoelectric Effect using UV light. The best UV light source to use is one with a quartz glass lamp envelope. Cat No. Description Price Per ECT-650-100 Zinc Plate 5.64 ea. 6 COULOMB METER For charge detection and measurement. Useful for a wide range of experimental applications including charging by induction, Faradays ice pails, Coulomb’s law and capacitance of an isolated sphere. The 3.5 digit liquid crystal display has 13mm high digits with a wide field of view unobscured by trailing leads. The display also provides indication of polarity and low battery. The unit is exceptionally easy to read. Two colour coded 4mm sockets are located on the sides for maximum convenience and anti- slip feet are fitted to the base. Low operating current gives expected battery life in excess of 500 hours. Housed in a robust, ABS plastic case. Supplied with charge plate, battery and instructions. Range: 0 to 1999nC Cat No. Description Price Per ECT-170-100 Coulomb Meter 75.32 ea.
