COMPOUND PENDULUM (KATER’S) REVERSIBLE 1166
Consisting of nickel-plated metal rod 120 cm long, 10 mm dia. with one pair each of small and large adjustable brass and wooden masses, two steel knife edges set in adjustable metal holders and metal bracket support for wall mounting.

LEVER SIMPLE FORM 1167
For introducing the concept of equilibrium leading to an appreciation of the principle of beam balance. Consisting of a polished boxwood rule 1meter in length, divided in centimeters and millimeters on one edge, and inches and tenths on the other. Drilled every 2 cm. Without riders. Riders only for above lever, set of three: one acts as a fulcrum and the other two as weight hangers. Complete with hanger hooks.

INERTIA BALANCE 1168
Comprises two metal trays 130 x 55 x 23mm joined together with a pair of spring steel strips 10mm wide the distance between the two trays being 215mm. One tray is drilled to hold three equal cylindrical masses. The other tray acts as anchorage and can be clamped to the bench horizontally or vertically. Complete with three masses and a ‘G’ clamp for mounting. Overall dimensions 325 x 130 x 23mm.

CAPILLARY TUBE APPARATUS 1169
For demonstrating the relationship between capillary pressure and the bore diameter of the capillary tube. The apparatus comprises a metal frame, the base of which takes the form of a trough 115 x 40 x 10 mm. The upper part of the frame supports six capillary tubes, each of a different bore, their lower ends resting in the bottom trough. The trough is fitted with water and the difference in heights of the resulting columns of water in the tubes is readily apparent. Overall height of frame 90 mm, length of capillary tubes 150 mm.

BUCKET AND CYLINDER 1170
Brass nickel plated, 60mm long 20mm dia. Overall extended length 160mm.

SIMPLE PENDULUM BOBS STEEL/LEAD/BRASS 1171
Solid spheres with a hook for suspension available in three sizes. Diameter:
a) 13mm
b) 18mm
c) 25mm
Also available COMPOUND Pendulum and KATER Pendulum.

HYDROMETER NICHOLSON 1172
Hollow brass body nickel plated 250 x 35mm dia with upper loading pan and lower loaded weight cone.

HYDROMETER UNIVERSAL 1173
A direct reading relative density hydrometer streamlined form with parallel graduated stem and shot loaded bulb, all glass. Range : 0.700 to 2.000 x 0.010 at 60ºF. Overall length 370mm approx.

SMOKE CELL 1174
For the observation of ‘Brownian Motion’ in smoke particles. Consists of a box with plastic lid as well as flanges that allow easy attachment to standard microscopes. The box contains a smoke cell, cylindrical condensing lens and a 12V 3W festoon bulb. Apparatus preset to focus the light at correct height. The set is supplied complete with detailed instructions and a squeeze bottle type smoke generator. Dimensions 90 x 46 x 20mm.

DISPLACEMENT VESSEL 1175-A
Metal, large size, with overflow outlet for specific gravity experiments.

DISPLACEMENT VESSEL 1175-B
Glass, medium size, with overflow outlet for specific gravity experiments.

EQUALITY OF PRESSURE IN LIQUIDS (Pascal Law Apparatus) 1177
To demonstrate the equal transmission by liquids of pressure in all directions. Comprising glass flask with holes and glass piston.

BATTERY HYDROMETER 1178
Glass hydrometer range 1100-1300 with coloured zones blue, white and red for charged, partly charged and uncharged conditions provided with compressible rubber bulb and rubber tube fitting to the body.

BERNOULLI’S TUBES 1179
To demonstrate the Bernoulli effect produced by water-flow. Comprises a Bernoulli tube, with central constriction, a constant-bore gradient tube, 6 lengths glass tubing, 2 swan-necked outlet tubes and 8 pre-cut lengths of rubber connecting tubing. The 2 flow-tubes, each 500 x 13 mm. Length 25 mm x 150 mm spacing, extended to form 500mm. Manometers with the lengths of glass tubing.

BOYLE’S LAW APPARATUS 1180
Simple type consists of a 50ml polythene syringe held firmly in a strong and stable base, and another flat piece is attached to the syringe piston. When the weights are placed on it causes compression of air. Air bleed valve provided. Dimensions: l00x100x180 mm height.

BOYLE’S LAW APPARATUS 1181
Designed for precise readings over a wide range of pressure. The flexible tube has a funnel at one end and connects to a glass tube that has a stop cock, a meter stick is mounted between the two tubes. The apparatus has a sturdy aluminum frame with metal base. Mercury not include; order separately.

BOYLE’S LAW APPARATUS (High Precision) 1182
A wide bore glass tube is mounted vertically in front of a scale graduated 0 to 60 cm. Zero corresponds to the inside of the closed (top) end of the tube. Air is confined in the tube by a coloured oil contained in a metal pressure chamber which is fitted with a Bourdon-type gauge calibrated 0 to 50 Lbs/In2 & 3.5 Kg/cm2 actual pressure. A valve is fitted to the air inlet tube from the pump. As the pressure in the oil chamber is increased oil is its actual (total) pressure are directly indicated. The tube is of extra strong glass and plastic safety screen is secured and fitted on front. Overall height of apparatus 690mm approx.
