Fluorescent protein flashlight and glasses

Dual Fluorescent Protein Flashlight



The Dual Fluorescent Protein flashlight is a portable, battery-operated flashlight that includes two different, switch-selectable high intensity LEDs for excitation of fluorescent proteins or other fluorophores, and comes with matching barrier filter glasses and a handy carry/storage case.

What wavelengths are available?

We can provide flashlights containing any two of the excitation colors that are available with our popular Model SFA Stereo Microscope Fluorescence Adapter.

 

  • Ultraviolet – excitation 360 – 380 nm, emission 415nm longpass
    • DAPI, Hoechst, …
  • Violet – excitation 400 – 415 nm, emission 460 nm longpass
    • BFP, CFP, …
  • Royal Blue – excitation 440 – 460 nm, emission 500 nm longpass
    • GFP, fluorescein, calcein, lucifer yellow, …
  • Cyan – excitation 490 – 515  nm, emission 550 nm longpass
    • YFP, Venus, …
  • Green – excitation 510 – 540 nm, emission 600 nm longpass
    • DsRed, TdTomato, RFP, …

What comes with the DFP?

With the DFP light you receive two pairs of barrier filter glasses, a set of batteries, and a convenient storage case. The glasses are well matched to the excitation source so that they block the reflected excitation light while transmitting the fluorescence with high efficiency, providing excellent viewing contrast.


What are the part numbers for the different color combinations?

To specify your color combination, use the following part numbers:

  • DFP-1 – The original combination, with Royal Blue and Green excitation
  • DFP-xy – for any other combination, where ‘x’ and ‘y’ are the first letters of the excitation colors you want
    • U – Ultraviolet
    • V – Violet
    • R – Royal Blue
    • C – Cyan
    • G – Green
    • example – DFP-VC will have Violet and Cyan LEDs

What is the price?

  • DFP-1 – $755.00
  • DFP-xy – $815.00
