Evident CKX53 Phase Contrast Inverted Trinocular Unit

Description

Engineered for high-contrast inspection of unstained living cells, the Evident CKX53 Phase Contrast Inverted Trinocular Unit utilizes an infinity-corrected UIS2 optical path spanning 100x to 400x magnification. Widefield 10x eyepieces provide a 22mm field number. Pre-centered phase contrast rings speed up routine cell checks, though phase halos naturally soften fine intracellular boundaries.

A cast-aluminum inverted stand houses a quadruple nosepiece, pre-centered phase contrast slider condenser (NA 0.3, WD 72mm), and integrated transmitted LED illumination. The plain stage measures 200 by 252 mm with manual vessel positioning. Coaxial focus provides a 0.3mm fine stroke per rotation, paired with a 45-degree fixed trinocular tube offering 48mm to 75mm interpupillary adjustment, an integrated contrast shield, and dual camera light splits.

Key Features of Evident CKX53 Phase Contrast Inverted Trinocular Unit

Designed for IVF laboratories, stem cell research facilities, and tissue culture rooms where rapid screening of transparent specimens is vital. The integrated phase contrast system eliminates the need for manual ring centering when switching between 10x, 20x, and 40x objectives.

• Phase contrast Achromat objectives: 10x, 20x, and 40x optimized for IPC and IVC imaging
• Trinocular viewing head with 45-degree fixed inclination and 48mm to 75mm IPD range
• Widefield 10x eyepieces with an expansive 22mm field number (FN 22)
• Pre-centered phase contrast slider condenser (NA 0.3, WD 72mm) with 72mm clearance
• Integrated transmitted LED illumination providing 20,000 hours of consistent color temperature
• Spacious 200 x 252 mm plain stage with optional mechanical stage compatibility
• Coaxial coarse and fine focus drive with 0.3mm fine stroke per rotation

Phase Contrast Physics & Inverted Contrast Shield

The integrated phase contrast (IPC) optical train converts phase shifts from transparent cell membranes into amplitude differences, resolving mitotic spindles, cell boundaries, and vacuoles without chemical staining. The pre-centered condenser ring matches the phase plates across 10x, 20x, and 40x objectives without manual alignment. The Inverted Contrast Shield (IVC) enhances edge definition across plastic vessels, maintaining three-dimensional cellular relief while transmitted LED illumination prevents thermal damage to living cultures.

Stand Mechanics & Laboratory Ergonomics

The rigid aluminum stand resists lab bench vibrations to maintain optical stability during micro-manipulation. The low-profile stage allows swift manual movement of Petri dishes, flasks, and multi-well culture plates, while the 45-degree viewing angle prevents neck fatigue during all-day cell confluence evaluations.

• Pre-centered slider system allows rapid switching between brightfield and phase contrast modes
• Trinocular port offers 50:50 and 0:100 optical splits for simultaneous documentation
• Coaxial focus knobs operate with smooth mechanical damping and zero backlash
