Inverted Infinity and Phase Contrast Microscope

With a wide range of features for university and laboratory use, this advanced research microscope features infinity corrected and
phase contrast optics, halogen illumination and trinocular head. Complimenting the illumination system is the ELWD (Extra Long
Working Distance) 0.30 N.A. condenser with its 72mm working distance for larger sample sizes. The condenser is also adjustable,
to provide the optimum amount of illumination for each sample. This series includes built-in internal 110V-220V auto-switching
power supply. Ergonomically designed, professional frame with low-position coaxial focusing allows one-handed operation, making
extended use comfortable.
Supporting these advanced features is the stable “Y” designed stand. The inverted “Y” provides the necessary stability and weight
distribution to handle optional Epi-fluorescence attachments. This microscope is an essential tool when viewing living organisms
within nutrient medium in petri dishes or cell culture flasks.
