Product information

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.
