The whole column of mercury is visible. Scale is graduated in both English & metric systems. Zero point adjustment is carried by a screw clamp attached to glass tube. Complete fitted on a polished wooden board.
Glass tube 90 cm long with bulb on shorter limb.
Glass tube 90 mm long closed at one end.
To demonstrate that when a liquid flows through a tube having a constriction, the speed of flow is increased and pressure decreased in the constricted section.
Circular gauge reads 0 to 50 lb./in� x 1 & o to 3.5 Kg/cm� x 0.1 actual (total) pressure with clear perspex back so that the working parts may be seen.
Two glass tubes 220mm long x 8mm bore one closed at the top and other open. Lower ends of two glass tubes are joined by 1 meter of pressure tubing. Both tubes mounted on sliding brackets lockable in any position on metal support rods. Polished wooden stand with graduated scale 0-100 cms, with mms in centre and figured every cm on either side. Supplied without mercury.
This apparatus is designed to demonstrate to students that volume of air enclosed in the column is clearly visible to students. A wide bore glass tube is mounted vertically in front of a scale graduated 0-60 cm.
To demonstrate floating, suspension, & sinking in accordance with Archemede�s principle. Made of glass.
The apparatus comprises of four different shapes limbs projecting vertically from a common horizontal tube made of glass mounted on wooden/plastic round stand.
To demonstrate the transmissibility of fluid pressure. The apparatus comprises two metal cylinders 15 mm and 30 mm dia respectively fitted with piston and connected by a tube. The pistons are provided with rods terminating in plate forms for loading with masses required. The complete apparatus is fitted on a wooden base.
A standard car pattern with an integral pressure gauge from 0 to 4 kg/cm2 and rubber tube adopter. The pump has a cylinder and provided with integral pressure tube and standard type valve connector.
A working model to demonstrate the principles involved in the action of a force-pump.
A glass tube of 6mm bore is enclosed in an enamelled 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 ciste.
This apparatus is used to compare the densities of liquids. It comprises of three limbed glass tube side limbs 45 cms long and rubber tubing on the centre limb closed by mohr clip.
Un-mounted glass tube, limbs with a third short limb for connecting a suction tube.
The apparatus comprises a pumping cylinder dia 25mm x 350mm overall height, provided with a piston and a non return valve at its lower end. A side tube joined at lower end of cylinder is also provided with a non return valve..
Pipette type, comprising glass float calibrated having coloured zones for charged, partly charged and uncharged conditions. Compressible bulb and rubber tube with fittings to glass body.
For light liquids calibrated at 20�C. Combined scale range 70 - 10 & 700 bv- 1000. For heavy liquids, calibrated at 20�C; combined scale 1.000 to 2.000 & 0.70.
For liquid and solid density experiments, comprises hollow metal floatation body, upper loading pan, and weighted lower cone, all painted.
Having range of 60 degrees, made of glass with parallel graduated stem and shot-loaded bulb.
Jolly Air Thermometer bulb of mounted on a wooden frame that can be fixed at three places - up, middle , & down on the stand.
A working model of a clear glass to show and explain the principle involved. It has a cylinder of 25 mm dia and overall lengths of 350 mm, cylinder is provided with non-return float valves and outlet is by means of a side tube.
Four glass tubes of different shapes & cross sectional areas are connected to a common horizontal tube. Mounted on a base to show level of liquid is constant.
Glass jar with open top attached with 2 balloons attached to a Y tube simulate the lungs; the chest cavity & stout rubber sheet which acts as the diaphragm, demonstrating how the lungs are filled & emptied with air by the relaxation & contraction of the diaphragm muscle.
Cast Iron or Brass fitted with stopcock and handles. Two metal hemispheres having removable handle and stopcock to a vacuum pump. This demonstrates atmospheric pressure.
Made from glass tube, 6 mm bore, 8 mm outer diameter for use at moderate pressures, it is open at both ends & is supplied unfilled.
Differential manometer - pressure gauge & vacuum gauge closed tube fitted with mercury, stop cock and sliding mirror scale graduated 200 - 0 - 200 x 2 mm mounted on wooden stand.
Mercury for experiments packed in plastic bottle 500gms.
Tough made of porcelain having capacity of 150 ml.
To demonstrate that the pressure of a liquid varies with depth & not the shape of the vessel, it is a glass vessels, each of 4 different shapes mounted in leak proof metallic collars mounted on a metal base, with plastic bowl.
Comprises a glass bulb approx. 50 mm dia with holes & glass piston overall size 250 mm.
Sheet Metal cylinder 400 x 60 mm (h x d) having three orifices fitted with rubber corks and small glass tubes of narrow bore of the same size but at different heights, down one side. A wide base ensure stability.
