Z-Dimensions Are Not Created Equal

Posted: Wednesday, May 1, 2013

Z-DimensionCuvettes come in a variety of shapes and sizes, but one of the most important specifications of a cuvette is its Z-dimension. The Z-dimension of an instrument (cuvette holder or spectrometer) is the distance from the bottom of the cuvette chamber floor to the center of its light beam (see image). A cuvette’s Z-dimension must match the Z-dimension of the instrument with which it will be used.

 


Surgical Loupes Defining Differences

Buying Multi-Barrel Glass Capillaries

Posted: Tuesday, April 30, 2013

Multi-barrel glass capillaries are available at WPI. Multi-barrel configurations are designed especially for microiontophoresis. Because the capillaries are fused together during manufacturing, you will not need to twist them while pulling to seal the tips together. An inner filament in each barrel makes filling easy and fast.


Setting up OxyMicro and OxyMini

Posted: Tuesday, April 30, 2013

Oxygen measurement is simpler than ever. Just stick a disposable, oxygen-sensitive "spot" to the inside of a flask, beaker, test tube or bottle, and fill the container with the solution to be tested. Then, on the outside of the glass container, hold the fiber optic wand close to the spot to take a reading. As the spot reacts with oxygen, it gives off light, which is measured with the fiber optic wand. This ingenious system is highly accurate and affordable. Two different units (which use the same operating principles are available: OXY-MINI and OXY-MICRO.
