M2Bio
M2Bio Fluorescence System

The M2Bio is the original hybrid stereo/compound fluorescence microscope with continuous zoom capabilities in both stereo and compound. The M2Bio is well known throughout the biology community as being the “go to” fluorescence microscope for transgenic sorting and observation needs for genetics, neuroscience and developmental biology.

* Hybrid Stereo/Compound Fluorescence Microscope with continuous zoom
* Features Kramer's patented Quad Fluorescence Illuminator, holding up to 4 fluorescence cubes at once
* True Stereo for picking with a compound light path for resolving more faint fluorescence markers

INV-Bio
INV-Bio Fluorescence System

* The INV-Bio is an inverted version of the M2Bio Fluorescence System
* 5 position fluorescence turret system with 3mm light guide interface
* Ergonomically Efficient stage making manipulation easy
* DIC use for looking through petrie dishes

Quad Fluorescence Systems

Upgrade your Microscope to Stereo Fluorescence!
The Quad Stereo Fluorescence Illuminator was invented by Kramer to upgrade stereo microscopes to full fluorescence functionality. Your stereo microscope can be upgraded to stereo fluorescence with ease.
* Adaptable to most stereo microscopes
* Up to 4 fluorescence cubes with extensive filter set selection
* Patented 2 dichromatic mirror system

FBS 10
FBS10 Fluoresence Microscope

The FBS10 is the next logical step in hybrid fluorescence microscope design. This configuration was inspired by leading C. elegans researchers who needed better light throughput to identify weak fluorescence markers in transgenics without the need to remount live animals from plastic agar dishes.
* High resolution with long working distance
* NO slide mounting necessary! The FBS10 works through a covered petrie dish and agar environment
* Better light throughput than stereo
* DIC model available with condenser base and glide stage for fine positioning Click here for the FBS10 brochure.
