Replacing and Aligning the Bulb
Chapter 5, Maintenance and Decontamination contains instructions for replacing and
aligning the bulb. These instructions do not contain enough information to help you
properly align the bulb in all cases.
When it becomes necessary to replace the bulb*, replacement kits are available from
BioTek. PN 7330513 is required for standard models, and PN 7330516 is required for
ELx800UV and ELx800NB models. The kit contains complete instructions for replacing
and aligning the bulb. Please ignore the replacement/alignment instructions currently
supplied in this manual in Chapter 5.
If you have any questions or require further assistance, please contact BioTek’s Technical
Assistance Center (TAC). Contact information is provided on page x.
* The lamp is rated for an average life of 600 hours. The intensity of the lamp will slowly
drop over time until the run-time self check detects a low signal level. The reader will
display an error code at this time, indicating that it is time to replace the bulb.
