Laboratory

The laboratory consists of a 400-square foot prep room, and an adjacent 950-square foot wet lab. The prep room is equipped with a four-place analytical balance, two top-loading balances, and triple-beam balances of varying capacities. There is a jar-mill and reciprocating grinder in the room, and two intermediate, as well as a standard sized, Wiley Mills are also available. There are several microscopes and stereo zoom dissecting scopes in the prep room.

It is also equipped with an upright, low-temperature incubator, a bench-top autoclave, and both a large standing and bench-top centrifuge. There are two large upright, forced-air ovens available in the shop area for sample drying. This area also contains two large chest-type freezers for sample preservation, and large mechanical balances of various capacities.

Finally, there is a full-sized, PVC, wash-down, perchloric acid fume hood with a 77-tube digestion block in the prep room. Adjacent to the prep room are a 25-square foot walk-in refrigerator, and a 160-square foot autopsy room that is equipped for the routine examination of animals. The wet lab is equipped primarily for the inorganic analysis of plant, soil, and water samples. It is equipped with a 2 GPH, stainless steel water still. It has a separate Kjeldahl room with a fume hood.

The wet lab has available various sample handling equipment, including two reciprocating shakers and a small rotary shaker, both forced-air and gravity-convection ovens, upright freezer and refrigerator, various sized hotplates, hot and boiling water baths, and various filtering, diluting, and dispensing equipment.

Analytical equipment includes various routine pH, mV, and conductivity meters. There are both a small colorimeter/turbidimeter and a UV/VIS spectrophotometer equipped with a flow-through cell available. The wet lab also has available a flame emission/atomic absorption spectrophotometer. The laboratory is supervised by a full time Staff Research Associate.
