Description: WPI's microelectrode holder-half-cells couple fluid-filled glass micropipettes to high input impedance amplifiers. A Ag/AgCl pellet (or a silver wire) molded into the holder body provides stable potential. Electrical connection is made via male 2 mm pins or female 2 mm sockets. The pipette may be mounted axially or at right angles to the holder. Pipettes are held with screw-caps or rubber gaskets (without caps). Filling WPI microelectrode holders with electrolytes containing chloride results in stable electrode potential. Suitable electrolytes include KCl, NaCl and CaCl₂. Holders are supplied for standard WPI single capillary tubing of 1.0, 1.2, 1.5 and 2.0 mm outside diameters. (Call WPI regarding custom designs for other glass diameters.) The holder style you select will depend on your experimental application, space, and instrumentation.

Description: The FO-6000 is a continuous fiber optic light source featuring an extended visible part of the light source (380 to 1700 nm). It has a SMA fiber optic connector. Both, shutter and lamp can be controlled via a switch or external TTL triggering. This light source offers a wide assortment of applications. A special feature of the FO-6000 is its color balancing optics, which shifts the usable range of the light source from traditional 420 nm down to 380 nm wavelength. Due to its thermally controlled optical bench, it is particularly suitable for low noise and low drift applications.
