This timer is most suited for an investigational approach for students to gain sound understanding of the concepts of time and motion. Two pairs of sockets alternately start and stop the timer, one pair operating in make mode, the other in break mode. The start/stop switches can be either mechanical or electronic. The timer is auto-ranging for ease of use and has clear 13mm digital display and has robust metal case with durable powder coat finish. An illuminated on/off switch is mounted on the rear panel adjacent to fused appliance inlet. • Electrical Supply: 220-240 V AC 50-60 Hz • Dimensions (W x L x H): 179 x190 x 85 mm • Mass: 1.6 kg • Ranges: 0 to 9.999s; 10 to 99.99s; 100 to 999.9s; 1000 to 9999s • Accuracy: ±0.01%

For use as a light operated timing gate. Comprises a photodetector and light source each housed in a robust ABS case spaced 40 mm apart on a plastic rod. Light source housing has a battery compartment and on/off switch. Photodetector housing is fitted with pair of 4 mm sockets to allow connection to electronic timers. When the timing gate is switched on it creates a short circuit between the two output sockets, this then becomes an open circuit each time the light beam is interrupted. Consequently the timing gate can be used as a remote switching device in wide range of dynamics experiments.

Replacement Cartridge for Deioniser, Vision 125

A compact all glass still, which can be wall or bench mounted. Produces up to 4 litres per hour of single distilled water. Consisting of horizontal boiler with 3 kW heating element and double coil condenser which cools the distillate to around 30 °C. The boiler can be drained via a stopclock and cleaned without dismantling. Two independent, automatic safety thermostats are fitted to prevent overheating. Supplied with level control device which turns the heater off when the reservoir is full. Requires minimum flow of1 l/minute. Dimensions 540 x 160 x 410 mm (W x D x H)

Spare boiler for the Distinction water still, WA17601.

Spare heater for the Distinction water still, WA17601.

An economically priced, wall mountable, all-glass water still, producing 4 litres per hour single distillate. With two independent safety thermostats, condenser, boiler, 3 kW sheathed heater and screw thread connections. Includes acid addition port and drain cock system for descaling the boiler. Dimensions 500 x 150 x 450 mm(W x D x H).

This water still produces ready-to-use cold, distilled water. The high quality borosilicate glassware coupled with silica sheathed heaters gives pyrogen-free distillate of the highest purity from virtually any raw water supply. The boiler feed is pre-heated to increase efficiency. The unique condenser design ensures that the droplets of distilled water remain in contact with the cooling coil for the longest possible time ensuring maximum energy transfer. All-glass construction allows rapid descaling using strong mineral acids. built- in ""clean"" function and integral acid addition funnel make the cleaning operation simple and safe with no need to dismantle any of the glassware. large bore stopcock with PTFE key is fitted for easy draining of chemicals after cleaning. A flow sensing device prevents overheating, and allows the unit to run on water supplies with pressure as low as psi (20 kPa). Requires a minimum flow of 1 litre per minute. There is an over-temperature thermostat mounted in the boiling chamber as an additional fail-safe. The acrylic safety screen and the cabinet lid are removable giving easy access to the glassware components. Screw threads are incorporated on all water connections so hoses can be fitted and removed easily and safely without risk of breakage. The control is simple and effective system which can be fitted to virtually any type of reservoir vessel. It will turn the still off when the reservoir is full, and restart it when the level in the reservoir drops, making it fully automatic. • 4 litres per hour output • Highly efficient • Fully automatic • Built-in ""clean"" function • Wall mounting bracket included

This battery has a 7 year shelf life and are suitable for high drain rate applications (although lithium cells may work better in some applications). It also has better low temperature performance than Zinc cells.
