[Histonet] Request for Non-fluorescent Sealant

[Latremouille, John]

Hello, I am wondering if anyone would know of a sealant that is non-fluorescent (or doesn't leak). I am using a biorad duo chamber slide which has two slots for each chamber, I need to measure the fluorescence of some sample but Rubber Cement and the nail polish I have tried have both had some interfering fluorescence. Any help is appreciated!
