XIB400 Inverted Laboratory Biological Microscope for Research
The XIB400 is an inverted biological microscope with a Seidentopf trinocular head, Koehler illumination, and a quintuple nosepiece.

Product Overview
The XIB400 is an inverted biological microscope with a Seidentopf trinocular head, Koehler illumination, and a quintuple nosepiece. It supports infinity plan objectives from 4X to 40X with working distances from 3.4mm to 12.1mm, and includes phase contrast and epi fluorescence options. The 6V/30W lamp powers both transmitted and reflected light, and the 100W mercury lamp enables fluorescence imaging. It is designed for cell culture, tissue sectioning, and live specimen observation in research and teaching labs.

Problems It Solves
- Traditional upright microscopes cannot accommodate large culture dishes or plates
- Low contrast in transparent specimens like live cells is difficult to resolve without phase contrast
- Separate fluorescence and transmitted light setups require multiple instruments
- Manual illumination adjustment leads to uneven lighting and glare
- Lack of digital capture capability forces the operator to describe images instead of recording them
- Fixed light distribution in trinocular heads limits simultaneous viewing and recording
- Inconsistent focus and image quality across magnifications due to non-infinity optics

Use Guide
- Adjust the interpupillary distance to 48-76mm before focusing to ensure a single merged image
- Use Koehler illumination to align the lamp and condenser for even lighting
- For fluorescence, ensure the mercury lamp is warmed up and the correct filter is in place
- Use the 0.5x C-mount adapter if your camera requires focus adjustment
- Place the culture dish on the stage with the bottom facing up for optimal focus
- Use the 96-well plate holder for high-throughput screening and consistent positioning
- Detach the condenser when observing thick samples or large dishes to avoid interference

Frequently Asked Questions
What is the working distance for the 40X objective?
3.4mm. The working distance decreases with higher magnification objectives.
Can I use this microscope for live cell imaging?
Yes. The inverted design and phase contrast objectives are ideal for observing live cells in culture dishes.
Does the epi fluorescence unit require a separate power supply?
Yes. The 100W mercury lamp requires a digital power box that operates on 100V~240V input.
What digital cameras are compatible with the C-mount?
The C-mount 1x and 0.5x adapters support cameras from CANON, NIKON, OLYMPUS, and other standard brands.
Can I use the microscope without the condenser?
Yes. The condenser can be quickly detached for use with large or thick samples, increasing the working distance to 195mm.
What filters are available for fluorescence?
B, G, V, and UV filters are available. Choose based on the fluorophore used in your sample.
