●Allows easy recording of analytical data on DNA ladders prior to exposure to X-ray film. Can also be used on cling wrap  covering the DNA markers.
●Water-soluble phosphorescent material (non-toxic, non-radioactive) fluoresces after exposure to light and the exposure/fluorescence process can be repeated multiple times.
● No wastage as the fluorescent substance allows simple alignment of written data with the film as a guide.

Use pen to record letters or symbols directly on the DNA ladder or on cling wrap covering the DNA markers.

Always replace the cap after use.

Letters or symbols written using the Bio-Imager Pen absorb light when in light conditions and release the energy absorbed as light when in dark conditions. Film is exposed to this light and is developed as an image.
