3. The lamp base has two prongs which push into a socket at the back of the lamp housing.
To remove the lamp, grasp it firmly at the base and pull it straight up.
Caution: Never touch the lamp with bare fingers. Quartz halogen lamps can be destroyed
by the oil from skin. Use a tissue or soft cloth to remove the lamp. If the lamp is con-
taminated with oil or dirt, clean with a dry soft cloth.
4. To install a new lamp, slide the new lamp into the socket on the base of the lamp hous-
ing. Close the lamp cover and push the fastener to lock.
5. Turn the instrument on and inspect the sample compartment to ensure that the lamp is
lit.
7.3 Cleaning Up a Fluid Spill
The fluid handling system, an integral part of the VersaFluor Fluorometer, provides easy
cleanup in case of spills. By using a special purpose optical bench and a drain pan, the
VersaFluor Fluorometer is able to minimize the delay caused by fluid spills (< 2 ml). If a spill
is apparent, no electrical hazard is created because the fluid is contained by the fluid handling
system, a collection of components designed to hold and manage fluid spills.
1. Turn the instrument off and unplug the power cord.
2. To clean up spills, open the sample compartment and remove the cuvette holder by press-
ing the two tabs inward and pulling upward. Remove the two filters.
3. Using a clean cotton swab or cloth, dry all three cavities: the excitation filter slot, the
emission filter slot, and the cuvette holder cavity. Insure the glass lenses and mirror are
dry. Do not apply excessive pressure on the lenses and mirror while cleaning. Dry the
entire cuvette holder and filters.
4. Replace the cuvette holder and filters into the sample compartment.
5. Since fluid can accumulate in the drain pan, two drainage tubes are provided to allow
overflow fluid to exit the instrument. The overflow fluid will drain out the bottom of the
instrument. Clean up any fluid under the instrument. A few drops of fluid may continue
to leak out the bottom of the instrument after a spill. Check the area under the instrument
periodically for any signs of spills.
