XAB400 Lab Biological Microscope for Shcool Biological Observation

XAB400 Lab Biological Microscope for Shcool Biological Observation

XAB400 is a laboratory biological microscope from Nanjing AMADA Instrument Co., Ltd. designed for school biological observation and basic research. It features an infinity plan optical system with a Seidentopf binocular or trinocular head, quintuple nosepiece, and mechanical stage with integrated slide holders. The microscope supports multiple illumination and accessory configurations including Koehler illumination, phase contrast, dark field, polarizing, and fluorescence attachments.

  • Infinity plan objectives for sharp, flat images across the field of view
  • Adjustable interpupillary distance (48–76 mm) and 360° rotatable head for ergonomic viewing
  • Standard 100V–240V wide voltage halogen lamp with Koehler illumination for consistent lighting
  • Optional phase contrast, dark field, polarizing, and fluorescence units for advanced applications
  • Built-in C-mount and digital camera adaptors for image capture and documentation

Technical features

  • Seidentopf binocular head: inclined 30°, rotatable 360°, interpupillary distance 48–76 mm
  • Trinocular head option with light distribution: 100:0 (eyepiece only) or 80:20 (trinocular 80%, eyepiece 20%)
  • Quintuple nosepiece with 4×, 10×, 20×, 40×, 100× infinity plan objectives
  • Additional objectives: 2.5×, 60×, 100× (water immersion) available as optional
  • Mechanical stage: 182 mm × 140 mm size, travel range 77 mm × 52 mm, two-slide holder included
  • Swing-out condenser with N.A. 0.9/0.13, iris diaphragm, and field diaphragm with center adjustment
  • Koehler illumination with 6V/30W halogen lamp, 100V–240V wide voltage input
  • Filter holders: blue, green, amber, grey filters available (green, amber, grey as optional)

Who it is for

  • Secondary and higher education institutions for biology teaching
  • School science departments sourcing standardized lab equipment
  • Procurement managers in educational suppliers specifying microscopes with modular accessories
  • Training centers requiring microscopes that support both visual and digital output

Use guide

  • Select binocular or trinocular head based on whether camera documentation is required
  • Choose objectives based on required magnification and working distance (e.g., 2.5× for large specimens, 100× for high detail)
  • Add fluorescence or phase contrast units when observing transparent or low-contrast samples
  • Use C-mount or camera adaptor when capturing images for reports or presentations

FAQ

What is the working distance for the 4× objective?
12.10 mm for the PLAN 4× objective.
Can I use a digital camera with this microscope?
Yes. The XAB400 includes 1× C-mount and 0.57× C-mount (focus adjustable), plus adaptors for CANON, NIKON, and OLYMPUS cameras.
Is phase contrast available as a standard feature?
No. Phase contrast unit is optional and requires separate purchase with turret or independent slot.
What type of lamp is used?
6V/30W halogen lamp with 100V–240V wide voltage input.
Can I use immersion oil with the 100× objective?
Yes. The PLAN 100× / 1.25(S, Oil) objective requires immersion oil for proper use.
