Can I use a filter labeled as EM on the EX wheel

February 06, 2012

BMG LABTECH filters have a number on the side of the filter and some of the filters have an EX or EM in front of the number.

If there is an EX or EM before the number, such EX544 or EM590, then those filters can only be used for excitation or emission, respectively. If there is no EX or EM in front of the number, then that is a general filter that can be used for either excitation or emission.
