Designed with microprocessor-controlled dual thermocouples, this stirring hot plate offers accurate temperature control and protection from overheating. The analogue models feature a coloured LED indicator which surrounds the heat control knob illuminating the actual surface temperature in real time. Powerful magnets and motor provide stirring speeds of up to 2000 rpm and mixing capability of up to 15 L of liquid. The square plate design allows flexibility of vessel sizes and combinations. Up to four 250 mL beakers can easily fit on the surface at the same time. To keep you safe, a “hot” warning light flashes whenever the plate surface temperature is above 50°C and continues to flash until the temperature drops below 50°C, even when unplugged. The unit includes BioCote antimicrobial protection which reduces the presence of odour and stain causing microbes such as bacteria, mould, and fungi on the product surface by up to 99.99%. Formulated from silver ion additives, BioCote provides built-in antimicrobial protection to support a more hygienic laboratory environment. This model includes an integral fitting for a retort rod and allows the retort base to slide underneath. Featuring a chemically resistant glass ceramic top plate that stays cool around the edges to help prevent burns. Please Note: BioCote® technology does not protect users or others against disease causing bacteria, germs, viruses, or other harmful organisms. This technology is not a substitute for good hygiene and/or cleaning practices.

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.

Apparatus for measuring rates of absorption or evolution of gases from organisms. Comprises two stoppered boiling tubes with wire baskets to support organisms. Each boiling tube is connected to simple manometer tube via three-way tap. The manometer tube is mounted on scale to measure the position and movement of the liquid level as gas is evolved or absorbed. The organism of interest is placed in the basket of one of the tubes, which also has some potassium hydroxide solution to absorb carbon dioxide. The other tube acts as thermobarometer, to counteract changes in temperature. Full instructions are included.
