I think you have a common UV lamp without a special narrow optical filter. Do you see a blueish light of this lamp? If yes, it means that this lamp most probably will be good for your dye. The reason is that the lamp emission covers rather broad spectral range, from short UV to shortwave visible light. So it covers 302-312 nm, and perhaps even alloows to work in 365 nm region.

Thanks Igor for your rapid answer.

In fact, the lamp allows the set in 254 and 366 nm, so it makes sense to cover 302 nm,

I'll try it! Thanks again

Hi Pablo,

Be careful however that exposition to UV light will damage your DNA, which is not the case with the 302-312 light. So if you want to cut bands in a gel  to purify the DNA and use it for other purposes, don't let your gel stand too long under the UV lamp and work as fast as you can.
