Easy zero adjustment and color coded. See Enlarge Click to Enlarge CAPILLARY TUBE SET (COMMUNICATING CAPILLARIES) For demonstrating that capillary rise is dependent upon the inner diameter of a tube. Proves that the molecules of a liquid are more attracted to glass than to other liquid molecules. Consists of four glass capillary tubes of different inner diameters with a large tube serving as reservoir. Mounted on a stand. Height of the tubes is about 15cm.. See Enlarge Click to Enlarge EQUILIBRIUM TUBES (CONSTANT LEVEL TUBES, COMMUNICATING VESSELS) For showing that liquid levels are independent of shapes of the containing vessel and liquid will rise to the same level in the vessel, regardless of its shape. Consists of a reservoir and three tubes of borosilicate glass of same internal diameter but different shapes. Mounted on a stand. See Enlarge Click to Enlarge PASCAL VASES For demonstrating that the pressure of a liquid at the bottom of a vessel is proportional to the depth of the liquid and is independent of the volume and shape of the vessel. Consists of three borosilicate glass vessels of different shapes, open at both ends, having ground edges and bottom openings of equal size. Provided with plastic disks and attached hooks and strings so that when vessels are immersed, bottom down, water pressure holds the disk in place. Used to show that the depth of the vessel when water is poured inside it, is independent of the shape of the vessel. See Enlarge Click to Enlarge VENTURI APPARATUS For demonstrating Bernoullis principle that any restriction in fluid flow results in increased speed and decreased pressure. Comprised of borosilicate glass tube 18cm (7in) long and 18mm ( 3/4in) in diameter with a constriction in the centre and three vertical openings in different sections. Includes three glass manometer tubes and rubber connecting tubes for measuring pressure at three locations. Ends are flared. See Enlarge Click to Enlarge HOOKE'S LAW APPARATUS For proving Hookes Law of Elasticity, i.e. that elongation of an object is directly proportional to the load applied and demonstrating the phenomenon of simple harmonic motion of a vibrating weight, potential energy etc. Consists of an adjustable mirrored scale 15cm long, graduated in millimeters, mounted on a support rod 30cm long fitted on a base. A hook attached to the rod supports a spring and indicator. Provided with a 50g brass hanger. Required slotted weights can be ordered separately. See Enlarge Click to Enlarge SPRINGS, EXTENSION STEEL For demonstration of Hookes Law and use with Hookes Law Apparatus. Closely wound springs of diameter 6mm with loops at both ends. Made of 26SWG wire. Average extension for a 250g load are indicated below. Springs with specific enlongations can also be supplied. See Enlarge Click to Enlarge HOOK COLLARS For suspending spring balances, cords, pendulums and other apparatus from support rods or cross members. These metal collars are fitted with thumbscrews. See Enlarge Click to Enlarge PLUMB BOB Made from hexagonal steel rod by carefully machine turning to a sharpened point. Dimensions are approx. (l x d), 85 x 20mm (3 1/3 x 25/32in) and weight approx. 140g (5oz). Provided with a screwed end cap with a hole to receive a cord. See Enlarge Click to Enlarge FORCE TABLE For performing static force experiments in mechanics such as studying the condition of static equilibrium of a rigid body under the action of forces in a common plane i.e. for the verification of the laws of composition and resolution of forces. Can also be turned into a teaching spectrometer by using appropriate collimator assembly, telescope and a support for prism and grating. Comprised of an accurately machined aluminum table 40cm in diameter graduated in 360? on its rim. Mounted on a heavy vertical support rod and tripod base fitted with levelling screws. Body under study is a ring in the centre of the table fastened by strings passing over four low friction pulleys attached with the table. Provided with four weight hangers of 50g each and four sets of brass slotted weights (each set consists of the masses: 2 x 10g, 2 x 20g, 4 x 50g, 4 x 100g). See Enlarge Click to Enlarge PULLEY SET An economical set of Pulleys, ideal for experiments with light to moderate loads. General construction is of tough moulded plastic, the pulleys themselves being 50mm diameter and carried on free running steel spindles. The set comprises two single pulley blocks, one double pulley block and one triple pulley block. See Enlarge Click to Enlarge PULLEY-SINGLE PLASTIC Polypropylene pulley of dia 50mm mounted in an aluminium frame with hooks. See Enlarge Click to Enlarge PULLEY-SINGLE METAL Made of aluminium, dia 50mm mounted in an brass frame with hooks. See Enlarge Click to Enlarge PULLEY-SINGLE BRASS Made of brass, dia 50mm mounted in an brass chrome plated frame with hooks. See Enlarge Click to Enlarge PULLEY-DOUBLE PARALLEL PLASTIC With two wheels of polypropylene pulley of dia 50mm in an aluminium frame with hooks.
