COLO.Science — ROMI420B INFINITY BINOCULAR BIOLOGICAL MICROSCOPE (UPRIGHT)
ROMI420B Infinity Binocular Biological Microscope
ROMI420B is a research-grade biological microscope for routine work and more advanced applications in education, laboratories and biomedical fields. It is built around Infinity Plan-Achromatic objectives, supports Köhler illumination, and offers a stable light source (LED or halogen) with an energy-saving mode and automatic switch-off after inactivity.
Köhler illumination
Binocular head (tilt 10–45°)
3W LED or 20/30W halogen
Auto-off (up to 2 h)
Reversed nosepiece (5 objectives)
USB port for power bank (mobile use)
Why ROMI420B is a solid choice for daily laboratory work
- Köhler illumination: precise light control for better contrast and uniform field illumination.
- Infinity Plan-Achromat optics: clean, flat image suitable for routine, teaching and standard lab workflows.
- Stable light source: 3W LED or 20/30W halogen with smooth intensity control.
- Energy saving & practicality: programmable auto-off (up to 2 h) plus an integrated carrying handle.
Overview
ROMI420B is an upright biological microscope with a binocular viewing head for transmitted-light observation. It is designed as a stable platform for labs that need reliable performance, easy handling and configuration flexibility (illumination, optics and optional features such as HDMI output).
