For illustrating expansion by heating and contraction by cooling. Comprising a mild steel bar 110 x 10 mm length x diameter, on rod with wood handle, overall length approx. 28 mm with metal cast gauge, sliding fit over ends of bar and with hole 10 mm bore in one arm. They are available in different designs.

To show the forces which can be exerted during thermal expansion or contraction. Comprising a heavy cast iron frame 340 x 120 x 100 mm with slotted end pillars to carry a stout iron bar. The bar is 9 threaded at one end for a large tensioning nut and has holders at the other end to accommodate the cast iron breaking bars. Supplied complete with ten breaking bars.

Comprising of a U-shaped glass 15 mm in dia. With one plain limb 220 mm long, one graduated limb, overall length 120 mm. Limb graduated 25 to 35 x 0.2 ml terminating in bulb 34 mm diameter with third limb 185 x 6 mm length x bore, joined at right angles to the plain of the other two. Short length of the rubber tubing with two pinch clips on short length of glass tubing mounted at end of wide-bore limb with rubber bung. With tall farm beaker 1000 ml capacity and stirrer. All glass parts from borosilicate glass.

We also manufacture hydraulic press bramah to be used for varied industrial purposes. It is manufactured to apply large lifting and compressive force. It is manufactured based on the Pascal's principle. Our hydraulic presses are efficient form of modern press. The press is manufactured using borosilicate glass which adds to its durability and enhances its functioning.

For determination of the thermal conductivity of bad conductor cylindrical metal slan nickel-plated 110 mm diameter 12 mm thick, on this rests a steam chest made of brass nickel-plated 50 mm height same diameter fitted with riffled inlet and outlet tubes. Both are having radial holes for insertion of thermometers apparatus is suspended by strings attached to lower slab on retort stand with rectangular metal base complete with one each disc specimens of glass and ebonite annulus for determining the conductivity of liquids, without mercury.

We offer ring and ball stand, applicable in the field of thermal expansion. They are manufactured with the use of brass, to enhance its functioning. The sensitive character of the brass ball aids in its delivering accurate results. It is applicable in demonstrating thermal expansion of matter.

The ring and ball stand comprises of a captive brass ball of 22mm diameter. It has a ring which is adjustable and is mounted on a tripod base.

We also manufacture steam heaters to cater to varied industrial use. It comprises of a cylindrical copper vessel of 180 x 115 mm height x diameter. The steam heater also consists of a filling tube, steam vent and vertical tube. The tube terminates the chute passing through the side of the vessel. A brass tube is fitted in the central tube to carry the thermometer. The lower end is used to cut an angle and to seal the chute. They are manufactured with attention to deliver enhanced results.

A class kit of eight sets of eight different wires of rods each 250 mm long for comparing the thermal conductivities of different mateials.

Type	Diameter (in mm.)	Conductivity
Glass	3	0.65 (Nominal)
Aluminium	3	240 (Nominal)
Copper	1.5 and 3	395 (Nominal)
Brass	1.5 and 3	128 (Nominal)
Iron	1.5 and 3	72 (Nominal)

We offer our clients ring and ball, applicable in thermal expansion. It is highly efficient in demonstrating thermal expansion in experiments. It comprises of a brass ball of approximately 22 mm diameter which is secured to a mounted brass ring by a chain. The ring is further mounted on a rod with the help of a wooden handle. The ball easily passes through the ring when cold, and its sensitive nature allows it to be heated easily. Then after being heated it does not pass through the ring, hence the concept of thermal expansion can be demonstrated using it.

We also offer ring and ball mounted, for the demonstration of thermal expansion. In this the ring and the ball are mounted on separate handles. This facilitates the demonstration process and aids to its easy experimentation. It comprises of a brass ball and a brass ring. Both mounted on different wooden handles.

Comprising strips of copper, iron, aluminium and brass fixed on wooden ring meeting in the centre, outer ends of the strips formed with small cups.

Polished with aluminium, the calorimeter have 75 x 50 mm diameter with wood / plastic lid fitted with rubber stopper and stirrer.

Calorimeter with copper polish in case of 3" x 2" (7.5x 5cms.) with outer rectangular teak wood polished box has a, thermometer holder and copper stirrer.
