An Efficient, Easily Constructed Cell Homogenizing Press

Easily Constructed Microscale Spectroelectrochemical Cell.

The design and performance of an easily constructed cell for microscale spectroelectrochemical analysis is described. A cation exchange polymer film, Nafion, was used as a salt bridge to provide ionic contact between a small sample well containing a coiled wire working electrode and separate, larger wells housing reference and auxiliary electrodes. The cell was evaluated using aqueous ferri/fer...

An Efficient and Easily Constructed Drip-Regulator for Transfusions

Easily constructed soil percolation apparatus.

The construction of a soil percolator from a disposable Nalgene sterilizing filter is described.

Easily constructed spectroelectrochemical cell for batch and flow injection analyses.

The design and performance of an easily constructed spectroelectrochemical cell suitable for batch and flow injection measurements are described. The cell is fabricated from a commercially available 5-mm quartz cuvette and employs 60 ppi reticulated vitreous carbon as the working electrode, resulting in a reasonable compromise between optical sensitivity and thin-layer electrochemical behavior....

An easily constructed carbon fiber recording and microiontophoresis assembly.

Traditional multibarreled pipette electrodes are still widely used in microiontophoresis studies. Although better electrodes have been introduced, they are difficult and time-consuming to make. Construction of a carbon fiber recording and microiontophoresis assembly is described here. The construction of a carbon fiber electrode assembly is easy and carbon fibers have excellent characteristics ...
