DESCRIPTION :-
• Comprising six equal rods of copper, iron, lead, brass, zinc, and aluminium,
each 130 x 3mm diameter, mounted in corks with their lower ends in a
tank, 210 x 75 x 75mm.
• The tank is supported on four legs at a height of 170mm above the bench.
• In use the rods are lightly coated with paraffin wax and the rates of melting
compared.
• One year warranty

DESCRIPTION :-
• Thick felt jackets for copper, aluminum calorimeters.
• Includes a felt mat for insulating the bottom.
• For calorimeter diameters of 50mm, 65mm, 75mm.

DESCRIPTION :-
• A lightweight cart with rubber tyred wheels .
• Fitted with a low consumption motor and a high efficiency solar battery.
• In reasonably strong, clear sunlight the cart will travel at brisk walking pace.
• For effective operation clear sunlight is a necessity.
• The solar cell is detachable to allow it to be used for other purposes and
will give in excess of 2V in clear sunlight.
• Dimensions 120 x 100 mm.

DESCRIPTION :-
• A comprehensive kit for investigating the properties of silicon photovoltaic (solar) cells as a source of useful power, in an interesting and
practical manner.
• The kit comprises 8 individual 0.4V 100 mA cells.
• These may be accommodated i n the base 'tray' which provides physical
support and facilitates interconnection of the cells using the connector
strips provided.
• The cells may be linked in a variety of series, parallel or series/parallel
combinations to give desired output
characteristics.
• Also included is a low consumption
electric motor with mounting
components, connecting leads and
small fan to illustrate practical use to
which the system can be put.
• Dimensions of base tray 110 x 95mm.
• One year warranty

DESCRIPTION :-
• For demonstration the high temperatures that may be generated by
focusing sunlight in an appropriate manner, and illustrating an 'alternative'
method of heating.
• The apparatus consists essentially of a rear aluminized parabolic mirror
305mm diameter x 185mm focal length and a matt black copper receiver
vessel
• Carried upon an arm at the focal point of the mirror
• In clear sunlight the apparatus will rapidly boil water or melt many fusible
substances that are placed in the receiver.
• The furnace is supplied in self-assembly form
and includes a stand and full
assembly/operating notes
• One year warranty

DESCRIPTION :-
• A metal cube painted with different colours (black, white and silver) to
demonstrate heat transfer by radiation (Absorption, emission and
reflection)

DESCRIPTION :-
• Kit consists of a baseboard, terminals,
• A set of metal connection pillars and a number of clip-on flexible
connection strips and accessory units, allowing a variety of circuits to be
constructed quickly and easily.
• Phosphor-bronze connection strips are so designed that when flexed a
little they are easily slipped over the pegs where their natural spring holds
them in position and ensures a good electrical contact.
