Superior Observation of Live Cells and Large Specimens: Inverted Biological Microscope DBI-380

Achieve clear, stable imaging of cell cultures, tissue samples, and large or thick specimens with the Inverted Biological Microscope DBI-380—a high-performance instrument engineered for cell biology, microbiology, IVF labs, and biomedical research. Unlike conventional microscopes, the DBI-380 places the objectives below and the light source above the stage, enabling observation of samples in culture flasks, Petri dishes, and multi-well plates without transfer—minimizing contamination risk and preserving live-cell integrity.

Engineered for Live-Cell Imaging and Laboratory Flexibility

The DBI-380 Inverted Biological Microscope features a trinocular or binocular head (30° inclined), infinity-corrected optical system, and long-working-distance plan-achromatic objectives (typically 4x, 10x, 20x, 40x). Its LED Köhler illumination provides bright, even, and cool transmitted light, while the large, unobstructed stage accommodates standard culture vessels up to 150 mm in diameter. Optional phase contrast, fluorescence, and digital camera modules enhance functionality for advanced applications.

Inverted Design for Culture Vessels – Observe live cells directly in flasks, dishes, and slides without sample transfer.
Infinity-Corrected Optics with Long Working Distance – Sharp, flat images even with thick-bottomed containers.
Bright, Cool LED Illumination (3W–5W) – Adjustable intensity; >50,000-hour lamp life.
Magnification Range: 40x–400x (expandable to 600x) – Ideal for cell morphology, confluency, and motility studies.
Optional Phase Contrast & Fluorescence – Upgrade for enhanced contrast in unstained live cells or specific labeling.
Robust Metal Frame with Ergonomic Controls – Stable, vibration-resistant, and easy to focus during long sessions.

Trusted in Biomedical Research, IVF, and Cell Culture Labs

From monitoring stem cell differentiation and checking bacterial contamination to performing oocyte assessment in fertility clinics, the DBI-380 supports critical workflows where sample viability and sterility are paramount. Its user-friendly design and optical clarity make it ideal for academic labs, biotech startups, and clinical cell therapy facilities.

Whether you’re tracking cell growth over time or validating culture conditions, the Inverted Biological Microscope DBI-380 delivers the reliability, flexibility, and image quality your life science research demands.

Observe life in its natural vessel. Work with confidence. Discover without disruption.
