Immersion Oils For Fluorescence Microscopy
After years of development and field testing, we now have available two new PCB-Free Immersion Oils for Fluorescence Microscopy.
* Immersion Oil Type HF
Type DF has been discontinued by Cargille. As an alternative we are offering either a new Immersion Oil called HF which would provide low fluorescence and the correct optical properties or you can use our FF which has virtually no fluorescence but slightly less than ideal optical properties.
