Designed for ease of use, the CP Series allows a novice to approach the microscope and quickly analyze their specimen. Void of complicated features, the CP Series offers pre-centered lenses and condensers, preventing operator confusion.

High eye point eye pieces, a rear facing turret for easy slide handling and a choice of lenses that provide large, flat fields of view offer brilliant images and outstanding resolution.

Built to take rough handling, the CP Series' frame, focusing and stage mechanisms are all metal construction because plastic wears over time. Spring loaded objectives protect against abuse but a focus stop control prohibits stage ramming accidents. Anti fungal protection and all glass light collectors ensure these microscopes will outlast their industry leading 5 Year Warranty.

  • Affordable - Portable
  • Durable - Easy to use
  • Five Year warranty

Dissection and observation of macro specimens is more enlightening with our Stereo microscope. The large stage allows ample room for sample manipulation but still fits in a storage cabinet. Their illuminated stands let you choose light from three directions - above, below or both, to help observe opaque or transparent samples. Solid, all metal focusing mechanisms will endure student use well beyond the five year warranty.

The ST-800 series two power stereo helps students down the road because they select magnification by turning a knob on the head, replicating a process on more sophisticated zoom models. Teachers like them because the eyepieces are locked and don't walk, the all metal frames are built to last and the low voltage bulbs last for hundreds of hours and are easy to replace. Even models with rechargeable illuminators are available.

The DG6 Series (replaces the ZM Series) allows infinite magnification changes throughout the range, making available a world of discovery for the student.
