Air Pump comprises of Cast Metal with metal valves. It comes with stopcock and is fitted on nicely polished wooden base Metal Plate & have diameter of 150mm.

Air Track Linear compromises of Triangular section Aluminum alloy track, length 255cm with staggered air holes at 25mm spacing approx, supported by two light alloy casting positioned 45cm from each end of the track. Each support has an adjustable knurled screw with fiducially rivet to facilitate track setting, one revolution corresponding to a height difference of 1.25mm Lateral and horizontal adjustable are made separately at the two and one point support respectively. V- slots are incorporated for positioning the four faced scaling rule. Vertical holes accommodate a quick action shutter with an integral cable release for use in stroboscope photography. Large catapult arms with slots for elastic bands are fitted to each end of the track. A pulley fitted to one end of the track enables experiments involving acceleration under a constant force to be investigated. Identical end caps enable air to be introduced from either end of the track, bung being supplied to close the end not being used. The knurled screw, catapult arms and pulley mountings are matt black finish to aid the interpretation of stroboscope photographs. Complete with supply of elastic bands.

Accessories Kit
Aluminum alloy vehicles have bee carefully designed to attain the optimum w eight of buffer attachments. Buffer attachments are located in holes 6.5mm diameter ad clamped by screw at each Ed of the vehicle. A vertical 4mm diameter hole in the center of each vehicle enables the white plastics rod to be used to indicate the positions of vehicles on stroboscope photographs. Vertical slots in the top of the vehicles enable white cards to be positioned for photoelectric timing applications. The vehicles buffer attachment and clamping screw are finished in matt black to the interpretation stroboscopic photographs.

The brass beam is 14cm. long with 100 notches graduation for rider use. Arrestments at fix points of stone agates. Balance base if of white sunmica wooden board. Case is made of seasoned wood nicely polished, capacity 250gm sensitivity 1/5mgm

For use with any liquid to measure to 0.001 densities up to 2.0999; a thermo- meter in the glass plummet indicates temperature. Bearings are of agate and hardened steel. Complete in wood case with plummet and platinum wire suspension, five rider weights. Cylinder of about 60cm3 Capacities

Two pan balance for accurate and rapid weighing up to 2 kg. The balance has two beams with centre reading sliding masses. These weigh up to 0-200gm x10gm, & 0-10 gm X0.1 gm, total 210gm; Supplementary masses extend the range to 2 kg. With spring loaded zero adjuster and magnetic damping, with stainless steel pans of 150 mm diameter.

Capacity 0-250gm, 0-1000g For trial weighting, for animal weighing for post- mortem examinations and in school science, a balance is often required which reads directly in grams and has a capacity of up to 1 kg. The double –range lever balance is in effect two balances in one. The low range scale is graduated 0-250x1gm. And the high range scale 0-1000x5gm. Swinging the counter- weight to one of two positions makes the change from one range to other. The scale marked white on black is read by means of an anti parallax cursor Finished in gray with all bright parts nickel – plated. Dimensions, overall 450x525mm height X width

With screen-printed scale and double hooks. Plastic/ metal body Gms and Newton scale s combined. Capacity 100gm 250gm, 500gm 1000gm and 1newton, 2.5newton, 5 newton and 10newton

Single pan, total Capacity of 2610gm (Using attachments weights) sensitive to 0.1gm The three beams are each provided with a sliding weight and are graduated 0-500x100g, 0-100 x 10gm and 0-10x0.1gm respectively, permitting reading up to 610gm without the use of attachment weight. Magnetic damping of the beam provides quick accurate weighing, with stainless steel pan 150mm diameter.

Accessories
Attachment weights up to Two 1 kg and one-500gm weights with stainless steel knife –edge suspension for attachments to suspension pivot on the beam, to increase the capacity of the valance up to 2610gm.
