Fisherbrand Inverted Phase Contrast Microscope with Trinocular Siedentopf Head and Infinity Optics

The Fisherbrand Inverted Phase Contrast Microscope is designed for precise live-cell imaging and transparent specimen observation, widely used in biotechnology, molecular biology, and biomedical research. Featuring an *inverted design* ideal for observing live cells and cultures from below through flasks, Petri dishes, or culture plates, this microscope supports advanced phase contrast optics for enhanced visualization of low-contrast biological samples.

Key technical features include:

• Infinity optical system with a backward-facing 5-position turret nosepiece, accommodating 4x, 10x, and 20x phase contrast objectives (Plan PH or LPlan sets) optimized for detailed cell morphology studies.
• An ergonomic *Siedentopf trinocular head* set at a 30° angle, equipped with 10x eyepieces featuring dual diopter and interpupillary adjustments, and an 82/20 eyepiece-to-camera light split for simultaneous observation and imaging—critical for fluorescence analysis and live-cell examination.
• A fixed stage measuring 240 mm (x) by 210 mm (y) with a 24 mm travel range and rack stop, facilitating safe sample handling during extended bioprocessing observations or tissue engineering assays.
• Coaxial coarse and fine focus controls with adjustable torque and fine focus resolution down to 0.001 mm divisions, allowing precise focal adjustments essential in synthetic biology and molecular diagnostics workflows.
• Power requirements of 100-240V 50/60Hz, 13 VA, ensuring compatibility across global laboratory settings.

This microscope provides a stable, well-balanced frame for extended use, making it suitable for cell culture labs, clinical diagnostics, and educational environments training next-generation biotechnology professionals. Its compact dimensions (9 x 23 x 21 inches) and weight (38 lbs) ensure both portability and bench stability.

Widely adopted in biomedical research and biomanufacturing, the Fisherbrand inverted microscope is essential for applications including live-cell imaging, cytological analysis, microbiology studies, and tissue engineering. Its phase contrast capabilities are critical for enhanced visualization in transparent or unstained biological specimens, supporting gene editing and molecular cloning efficiency by providing high contrast images without staining.

The integration of trinocular imaging makes this microscope well-suited for digital imaging workflows, supporting data documentation in molecular biology and biotechnology laboratories. Its robust design and ease of maintenance facilitate workflow optimization, a key requirement in high-throughput research environments.

Overall, this Fisherbrand inverted phase contrast microscope offers reliable optical performance and ergonomic usability, serving as a versatile tool for researchers and educators committed to advancing cell biology, neuroimaging, and biomedical engineering fields.
