Analgesia testing is a growing field. Before new pain killing pharmaceuticals are brought to market, they must undergo a host of efficacy studies involving some form of analgesiometry prior to any clinical trials. The standard nociceptive threshold testing for preclinical trials involve mechanical, thermal and chemical stimuli with mice and rats. WPI offers a variety of such equipment.

EZ Anesthesia is the system of choice for anesthetizing small animals, and it comes with a variety of choices. Animals to be anesthetized are placed in the acrylic induction chamber and the system delivers a precisely blended mixture of oxygen and isoflurane. An activated charcoal air filter canister at the top of the chamber releases safe, filtered air back into the room. A water-heated cage warmer or warming plate (ATC2000) is used to retain the animal body temperature while in the induction chamber. After the initial anesthetizing, the animal can be moved to the heated surgical water bed and positioned properly in the snugly fitted nosecone. A highly sensitive valve regulated by the animal’s breathing works with the nosecone to ensure non-rebreathing efficiency, .

Cuvettes and HoldersFor spectroscopy cuvettes, synthetic quartz can be used in deep UV applications and is recommended for fluorescent applications, as it does not exhibit background fluorescence. Our quartz cuvettes are shipped individually packaged. Our glass cuvettes are shipped in packages of 10 cuvettes. These economical quartz and glass cuvettes are ideal for precision measurements, because of the high quality materials used and the low manufacturing tolerances. Cuvettes 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. Compare manufacturers' Z-dimensions and learn how to measure a Z-dimension.

An emerging area of research (Live Cell Imaging) is growing rapidly. The number of PubMed articles published on live cell imaging has bloomed in the last several years, and is 10 times greater this year than in 2003. WPI, working in tandem with researchers from InVivo Scientific, has develop a cutting-edge line of products specifically for live cell imaging. In the past dead cells were stained and examined under a microscope. Now, small incubators can be placed on a microscope stagetop and live cells in culture can be observed directly. This opens a whole new world for exploration.
