TV1 Test Tube Vortexer. a quality vortex mixer featuring reliable and easy operation. Simply press down on the silicone mixing cup or select 'continuous' mode of operation. Speed selectable from gentle to vigorous to suit most applications.

WHS1 Water Heater Stirrer. provides accurate temperature control of water within a container or resovoir for long periods of time. It features digital display, water pumping, preset 37.0 and resettable saftey cutout.

Qa1 Quad Bridge Amplifier. A bank of four identical general purpose and affordable bridge amplifiers. They are suitable for use in the medical, Engineering and Industrial Sciences for connection with force transducers, pressure transducers and any other form of bridge-based measurement system.

ST2 Constant Current Stimulator. A battery powered unit that can be used to excite nerve and muscle fibres in elecro physiological experiments. It features fully variable constant current output up to 11 milliamps with the ability to provide up to 90 volts. It accepts a positive trigger input and the output current is presented as long as the trigger signal is applied. The output is electrically isolated from the trigger input.

ST3 Constant Current Stimulator. Functionally the same as the ST2 (above) but with the addition of an internal pulse width generator. It accepts a positive trigger input and has three pulse width ranges as well as a 'gated' and 'continuous' output setting. The output is electrically isolated from the trigger input.

SR1 Stimulus Reverser. a device that will alternately reverse the polarity of incoming pulses from virtually any stimulator, either constant current or constant voltage. This is particularly useful in stopping electrolysis build up on stimulating electrodes.

TC1 Temperature Controller. The 'ultimate' temperature controller. It will accurately sense temperature, and provide a calibrated output, from up to four different sensors. and using one of these, provide the driving power necessary to control the temperature of small resistive heating devices. It is ideally suited to the biological temperature range and the temperature outputs are suitable for connection to pen recorders or P.C.'s.

TX2 Temperature Controller. The TX2 Temperature Controller is a general purpose controller for the accurate heating of resistive heating devices. It is Microprocessor controlled and provides 0.1 deg.C accuracy of the heated device while a secondary thermister probe displays temperature of any location you desire.

MH1 Microscope Chamber Heater. The MH1 Microscope Chamber Heater is designed to heat the air within a chamber surrounding a microscope stage for imaging live cells. Designed for quiet and continuous operation, this heater senses the chamber temperature via probe placed inside the chamber.
