Crushing Cylinder or Can   (MC-1243)

To demonstrate atmospheric pressure, made of thin metal, with a tubule at one end, 14mm inside diameter to accepts a rubber bung.

Capillary Apparatus   (MC-1244)

This apparatus is used to measure surface tension by Capillary rise in a small bore. It comprises six glass capillary tubes 125 mm long, ends ground flat, of different bores, supported by a metal frame in a shallow metal trough.

Capillary Apparatus, Plate Type   (MC-1245)

Two glass plates, 125 x 125 mm mounted in a sheet metal frame with a shallow trough.

Capillary Tubes   (MC-1246)

Five inter connecting glass capillaries of different bores fused on a horizontal glass tube, demonstrates how surface tension accounts for phenomena of capillary. Mounted on stand.

Surface Tension Apparatus, Jaegar's   (MC-1247)

This apparatus is useful for finding out variation of surface tension with temperature and also variation of surface tension with concentration of a dissolved substance. It comprises a test tube 25 x 150 mm fitted with rubber stopper carrying a stirrer and a glass tube, manometer reading to 200 mm, 250 ml filter flask with stopper and dropping funnel, complete with connecting tubing, 500 ml beaker for water bath, adjustable pointer and three jets of different sizes, ends ground and polished.

Surface Tension Balance, Searle's   (MC-1248)

It comprises a cast metal bridge mounted on a triangular shaped stand adjustable for height and having a leveling screw with knurled head fitted to one corner. The bridge carries a steel torsion wire stretched across it, one end of which adjustable for torsion wire, by screw. At the centre of the wire a small clamp is fitted which carry light weight metal pointer with an adjustable counter-poise. From the notch near the tip of pointer is suspended a small mass pan with a hook fitted to its underside, to hang either a wire frame or a metal clip carrying a glass microscope slide 75x25x1 mm. The tip of the pointer move over a vertical scale graduated 6 cm subdivided in mm. Supplied complete with wire frame, micro slides clip, six glass microscope slides and spare length of torsion wire.

Buoyancy Apparatus   (MC-1249)

This is to demonstrate the Archimedes's principle of floating Bodies. It consists of a 1000 ml graduated glass jar with pouring lip. A 50 mm wooden ball is provided to study the volume of displaced water and to compare the weight of the ball.

Cohesion Figures   (MC-1250)

A set of wire frames are provided to study the existence of surface tension in liquids. Soap films are used to study the effects.

U-Tube Manometer   (MC-1251)

a. Scale 130-0-130 mm, Div 1mm
b. Scale 260-0-260 mm, Div 2mm

Barometer, Fortin   (MC-1254)

A glass tube of 6mm bore is enclosed in an enameled and lacquered brass case, mounted on a polished wooden board with plates for fixing on wall. Open plate reflectors, ring and screws for vertical adjustments. A dual scale graduated in 25 to 32 inches and 640 to 810mm is read by verniers moving by rack and pinion, reading to 0.002 inch and 0.1mm are enclosed in a glass cylinder. A glass cistern at the lower end of barometer is provided with an ivory point to adjust the level of mercury. A thermometer -10 to 50° C is provided on the wooden board. Supplied without mercury and glass case.

Barometer Fortin's With Glass Case   (MC-1255)

Same as but in wooden frame, glass case.
