- Compatible with 40x objective lenses

The PZO KFL condenser is a universal microscope condenser with interchangeable discs. It can be fitted with both phase contrast and darkfield discs (which can be mixed). Each disc is focused to perfectly match the microscope objective. PZO KFL = "Fluorescence Contrast" is an accessory to the PZO fluorescence kit and was originally sold with the PZO Biolar FL and PZO MB30 FL microscopes, among others. It can be used with any microscope from any manufacturer that accepts a 39.5 mm condenser, although the top lens can be replaced with a 37 mm lens.

# Examples of use

- if you have a PZO KFL condenser equipped with phase contrast discs and want to use darkfield with a 40x objective
- if the disc in your condenser is damaged (e.g., scratched)
- if you want this item as a spare part
