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 LDF
Extremely low fluorescence is achieved by Type LDF. It is the replacement of choice for the DF which is no longer being manufactured. The LDF possesses the highest resolution of the oils for fluorescence applications.
* Immersion Oil Type 37LDF
Low fluorescence immersion oil for use at 37°C. Distinct odor.
