## Summary description

Deltaoptical BioStage II (DO-3310) is a compound laboratory microscope designed for biological and educational use. It features a binocular head for comfortable observation, LED transmitted illumination for bright, stable lighting, and standard objective compatibility for routine brightfield microscopy of slides, cell samples and tissue sections. Suitable for classrooms, teaching labs and clinical sample examination.

## Long description

The Deltaoptical BioStage II DO-3310 is a compound laboratory microscope engineered for routine brightfield observation of biological specimens. Designed for biological and educational use, this model combines a binocular head for comfortable binocular viewing and LED transmitted illumination that delivers stable, energy-efficient light for slides, cell samples and thin tissue sections. The instrument accepts standard objective lenses and accessories commonly used in teaching laboratories and basic clinical sample examination, providing the necessary optical configuration for classroom demonstrations, student practicals and everyday laboratory inspection tasks.
Advantages
The binocular head improves viewer comfort during extended observation sessions and supports interpupillary adjustment for different users. LED transmitted illumination offers consistent, flicker-free lighting with low heat output and long lamp life, reducing maintenance and operating costs. The optical path and mechanical stage are suitable for standard brightfield techniques and routine slide handling, while the overall construction is adapted to frequent use in educational and laboratory environments.
Suitable for
Teaching laboratories and classroom demonstrations
Student practicals and biology courses
Routine brightfield observation of stained slides, blood smears and cell cultures
Basic clinical sample inspection and documentation
General laboratory tasks requiring compound microscopy
When it may not be suitable
This microscope is configured for standard brightfield work and may not be suitable for advanced techniques that require fluorescence, phase contrast, differential interference contrast (DIC), or polarized light. It is not intended for high-end research requiring ultra-high numerical aperture objectives, advanced imaging modules, or motorized stages.
Key specifications
Optical type: Compound biological microscope for brightfield observation
Head: Binocular head with interpupillary adjustment
Illumination: LED transmitted illumination (stable, low-heat light source)
Objectives: Compatible with standard DIN objectives for routine magnifications
Stage: Mechanical or plain stage suitable for microscope slides (standard slide holder compatible)
Focus mechanism: Coarse and fine focusing controls for precise focusing
Intended use: Educational, teaching labs, basic clinical and routine laboratory inspection
How to use
Place the microscope on a stable, level surface and connect the power supply for the LED illumination. Start with a low-power objective and centre the specimen on the stage using the slide holder and stage controls. Use the coarse focus to bring the image into view, then refine the image with the fine focus. Adjust the interpupillary distance of the binocular head and individual diopters if available to match the user’s vision. Increase magnification by rotating in higher-power objectives as required, and adjust illumination intensity to achieve proper contrast without saturating the image.
What to consider before purchase
Intended applications: confirm that brightfield observation meets your experimental or teaching needs
Compatibility with objectives and accessories commonly used in your lab
Requirement for additional modalities (phase contrast, fluorescence) which would need different equipment
Work environment: bench space and stable surface for microscope placement
Usage recommendations
For consistent results, use clean, properly prepared slides and start observations with low magnification before switching to higher powers. Allow the LED illumination to stabilise briefly after powering on, and store the microscope covered in a dry environment when not in use to protect optical components.
