To measure the quantity of water absorbed and given off by a transpiring plant.Consists of a glass vessel 250x50 mm with rubber stopper at top & a side tube graduated 0-15 cmx1cm

Compact unit to compare rates of absorption or evolution of gases by small organisms during respiration. Two stoppered boiling tubes are connected by three way taps at either end of a manometer . One tube holds the organisms and has a syringe for altering level of liquid in the manometer during setting up. The other tube acts as a control thermo - barometer

Plastics, with cords and hooks.One meter long with fulcrum lever is graduated in centimeters and is balanced on the fulcrum by a transverse groove cut midway in the length of the lever over knife edge of the fulcrum without weights.

For showing convection currents in air. Comprises of metal box, 220x100x100mm with a removable glass front, two chimneys and candle holder fixed to the base of the box beneath the left hand chimney.

A comprehensive kit of apparatus to enable students to investigate many aspects of electrostatic forces. The kit comprises of : 1 Electroscope, 1 Rubber (polishing cloth), 4 metalled polystyrene spheres, 1 plated wire hook, 1 reel nylon monofilament, 1 Electrophorus plate on insulating handle, 1 cellulose acetate strip, 1 polythene strip, 1 proof plane on insulating handle, 1 wire stirrup to support the above two items, 2 polythene tiles & 2 aluminium cans.

Distillation equipment to cover most of the needs of the average laboratory can be built from standard components. Distillation assemblies for specific applications however are available as complete units

Comprising a heavy cost iron frame with slotted end pillars to carry a spout iron bar the are is threaded at one end for a large tensioning nut and got a hole at the other end to accommodate the cast iron breaking bars. The instrument is mount for experiment to show the forces, which can be exerted during thermal expansion or contraction with 112 bars

For demonstrating the rate of heat conduction in five different metals. The kit consists of five metal rods, approximately 20mm in diameter and 40mm long equally spaced on a brass disc and mounted on an insulated handle. The rods are aluminium, brass, copper, iron and steel and each having a cavity at the end for holding paraffin.

For demonstrating longitudinal and transverse motions. Consisting of a number of eccentric discs supporting a series of metal rods. On revolving the handle, transverse waves are obtained. Longitudinal waves are obtained with bent rods running in a metal guide.

Objective :To plot a graph, current Vs intensity of Light at different value of voltages.
Features :Instrument comprises of DC Regulated Power Supply 0-3 VDC/150mA, two round meters for voltage & current measurement, LDR mounted on the panel, connections of Supplies & LDR brought out at 4mm Sockets. Lamp Holder with 60 W Bulb are given with this apparatus

For demonstrating the phenomenon of thermal convection in liquids caused by temperature variation. Consists of a rectangular shaped borosilicate glass tube (w x h), 15 x 21cm with a funnel shaped opening at the top for filling liquids. When this tube is partially filled with water and heated at one corner after adding a dye or potassium permanganate crystals or saw dust or aluminum powder, the movement of colors or particles illustrates the formation of convection currents.

Objective :To study the Frequency and Waveshape generated by a Hartley Oscillator.
Features :Instrument comprises of 30V DC Regulated Power Supply, circuit diagram Printed & components mounted on front panel.

Also known as Meldes apparatus. Used to study and determine frequency of A.C. mains. Consists of a steel wire passing through an armature having a horse shoe permanent magnet. Whole apparatus is mounted on a wooden base. Complete with pulley and scale pan.

Showing the Earth revolving around the Sun and the Moon around Earth. With a candle to represent Sun, manually operated

Extraction apparatus , soxhlet complete with Allihn condenser, interchangeable joint. Capacity 60ml (Small) 100ml ( Medium) 200ml ( Large)

Under different light conditions it can measure and analyse the gas evolved by water plants. The gas is circulated into a calibrated capillary tube, it is drawn into a plastic syringe and taken for further analysis. It consists of a white plastic panel (240 x 100 mm length x height) with miniature 3 way plastic tap, 2 syringes and a calibrated capillary tube approx.1mm bore. The specimen can be connected to the open end of the tube which is bent downwards.

A glass tube 15 mm dia with a side arm leading to a thistle funnel in rubber tubing has both its ends tapered and bent at right angles. One end would accept plant stem and the other is connected to a capillarty tube with mm scale, mounted on an L shaped stand.
