Polyox (polyethylene oxide) is a non-toxic, long-chain polymer with a high molar mass. Because of extensive hydrogen bonding, it is soluble in water. A solution of Polyox (approximately 1% w/v) behave
Students can quantitatively see how pressure on an object changes as it moves deeper under a fluid with this interactive density pressure manometer activity. A hollow drum covered with a rubber membra
(Falling Body Apparatus) Showing that horizontal and vertical motions are independent of each other. Consists of a wooden block 190 x 58 x 30 mm approx. with a pivoted L-section spring loaded metal launching bar with a trigger catch. On releasing
On a clamp, light alloy, 70mm dia. held in a metal bracket, with two clamping screws for bench and rod support respectively. Bracket may be clamped to a bench edge or similar 38mm thick support, screwed to flat surface, or held on 13mm, dia suppor
Top plate measures 11 inches in diameter and can be used with bell jars up to 9 inch diameter. Constructed of cast iron, the plate is equipped with a 3/8 inch hose connection, vacuum release valve, and rubber gasket to provide

To demonstrate the Lenz’s law and effects of electromagnetically induced currents. A ring launcher consist of the base unit and built-in vertical solenoid of thick copper wire with a removeable iron c
The ring launcher consists of a vertically mounted solenoid of thick copper wire with an iron core. The coil is energized with by pressing the push button on the panel. Two aluminium rings are supplied with the apparatus. These rings
50mm plastic pulley with ball bearing fitted on an aluminium boss with tapped holes and a clamping screw to accommodate rods up to 13 mm diameter. Tapped holes are provided so that the pulley may be fitted on to the boss with its axis of rotation
The heavy duty rotating platform illustrates the concept of rotational inertia. The platform can easily withstand weight of 80 kg. Solid, heavy metal legs and grooved platform ensures maximum stabilit
ZET-383 School Event Timer S.A.T.Z Designed For Schools Uncomplicated 100th second timer No alarm or beeper No clock colour coded buttons for easy reference Start-Stop-reset Times to 9hr59m59.99s
ZSC-98A School Stopclock The ZSC98A is specifically designed for use in schools. The highly accurate quartz stopclock is housed in a robust ABS casing. The two buttons are large and colour coded for clarity. The LCD display is also large and clear
Z382 School Stopwatch Easy to teach operation because each button is a different colour Theft deterrent 'School Stopwatch' printed on the front Buttons can not be pulled off Battery securely fitted behin
To demonstrate the Second Law of Motion in simple and accurate way, two identical balls one drilled, the other solid are used. When the release lever is triggered, the internal spring accelerates one
Sine and square wave generator (IPC-4744-W). Frequency range 5Hz to 50kHz in four switched ranges plus a fine control. Accuracy typically ±10%. The output amplitude is continuously variable from zero
The loosely coiled, entirely metal, spring can be used in scientific experiments and demonstrations. Traditional design 7cm diam.
Silly putty’ or ‘bouncy putty’ has long been available as an amusement but this type of material – properly known as visco-elastic polymer or dilatant compound – has serious engineering applications.
Smart wire' is a shape memory alloy (SMA) that changes its length with a useful pulling force when a small current is passed through it. (Minimum order = 1 metre. This is enough for 10 useable lengths).
